most powerful in wheel electric motor

I capped it out at 72V, but I also used a 52V battery to get to my racing destination at an empty track nearby. Add to this the fact that the entire operation is on 2-inch-wide tires, and available roads for this kind of testing arent freeway smooth. To demonstrate the performance, HyperPower teamed up with electric drag racers Top EV Racing and built a Top Fuel-style dragster powered by four of the motors for a combined output of 5,360 hp. Peak power is an average 55Nm, which isn't a lot, but it is marketed at riders with adequate fitness who want to ride further, in less time, instead of those cyclists who require a lot of pedal-assistance all of the time. High cadence and torque outputs can increase the risk of overheating a mid-drive motor. READ MORE: Full electric car advice and FAQREAD MORE: EV tech explained. The specified top speed is 28mph. Elaphe therefore anticipates considerable customisation and differing production cycles for each motor. Starter motors are still typically the most powerful electric motors other than traction motors. The Lectric XP 3.0 is a striking e-folder with 3-inch-wide tires on 20-inch wheels and an industrial-styled forged-aluminum frame. Its what we call our multiphysics approach, says Lampic. The Elaphe L1500 in-wheel motor achieves the highest torque densities of electric motors on the market, generating 1500 Nm of torque without using any gears. Yamaha markets a variety of e-bike motors for all applications, as part of its PW product line. 17inch 12KW Hub Motor 1) Motor Type: DC Brushless Motor. That maximises the surface area under which our cooling channels can run, as close as possible to as much of the copper as possible, Gotovac says. With over 700 Nm of peak torque, 75 kW of peak power and . 5,000W may sound intimidating, but riding with a rocket ship between your legs is actually pretty cool. As a result, the active part of the motor the electric machine with windings and magnets takes up just 30% of the overall weight, giving it a torque density of 460 Nm/litre, compared with what the company cites as its nearest competitor at 390 Nm/ litre. As the CEO notes, Elaphes proprietary holistic motor optimisation algorithm takes into account (among other information) a wide range of magnet parameters as it evaluates an overall motor design. More. It might be a touch too powerful for some road and gravel riding applications, but its size and shape could become a reference standard. Some of the potential areas where we might see the motors turn up include aerospace applications, mining, high-speed rail including hyperloops should the technology eventuate, and yes, even hypercars. By running these load simulations in a generative design process (with a constant stiffness target and through a set of proprietary criteria functions), the numerical software can identify all the geometric qualities necessary for minimising structural stress across the metals of the stator and rotor (while also keeping it lightweight and taking manufacturing constraints into account where possible). All rights reserved. There's no need for a gearbox or driveshaft. As with the previous fatigue simulations, both tests are performed in accordance with ISO 16750-3:2007. These simulations must show that the degree of deformation never exceeds a certain (undisclosed) value, thus ensuring no impact between the windings or permanent magnets can occur. Having been filtered through the industrial designers guidelines, the stator and rotor designs are then evaluated (together with connected structural interfaces for a holistic motor simulation) using multiphysics finite element analysis (FEA) testing. Honestly, at these speeds, I think a motorcycle is much safer. So, while in-wheel motors may save some space, their advantage isnt as clear-cut as it might first appear. Since rotors are made mainly from magnetic steel, theyre heavy. That would probably have reduced the rate of adoption, owing to the higher initial price point. Copyright 2021 High Power Media Ltd All rights reserved. Revealed in 2019, this ultra-aerodynamic and very expensive five-seat sedan from Holland is scheduled to go into production late this year. Perhaps an innovative boutique frame brand will be daring and integrate it into a road-going e-bike application soon. Lampic adds, We invest resources in defi ning the brake, bearing, suspension, control and other requirements, building simulation models and characterisation procedures to determine whether a COTS or custom bearing can be used. In addition to its in-house testing facilities, Elaphe also sometimes uses third-party testing facilities for more conventional or specialised tests, such as for vibration, shock, environmental IP rating and EMC. There should be heaps of bonnet space after chucking out the ICE and all its 20th century stuff, but OK perhaps the boot/trunk space might suffer a bit. Full-scale production should begin in September 2021, and the company says its holding 100,000 (non-binding) pre-orders for the big double-cab pick-up truck. With more riders commuting, the demand has grown for quieter mid-drive motors. The companies that make the most powerful motors for electric scooters today are Minimotors USA and Rion. The number of magnets we install varies but is quite high, usually exceeding 40 on the L1500. Once these tests confirm that the motor components undergo no damage, and experience no stator-rotor contact in the air gap (and that the bearing never overheats or reaches temperatures indicative of damage), the customer-preferred bearing can be integrated into the L1500. With more experience and our model accuracies optimised, we replaced the N40UH with N40SH, the latter being in the 150 C temperature class.. While we can use MOSFETs, IGBTs, SiCs and GaNs, weve found that the L1500 is most popularly paired with a COTS silicon IGBT inverter with a 200 kVA maximum output, installed on board the vehicle, Gotovac says. powered e-bikes feel a lot more like a traditional road bike to ride, with regards to handling agility. These begin with a vague CAD approximation of each component with a target level of structural stiffness, then repeatedly exposes them to different load simulations, (including differing combinations and quantities of them), over several dozen iterations. The Quark electric motor, from Koenigsegg, is the latest. Each has its benefits and pitfalls. Rated Power: 5000W Voltage : 48V-120V KV : 9KV Max torque : > 250N.M Efficiency : > 90% Hall sensor : yes, have two sets, one is for spare Temperature : Yes Drop out : 150mm Axle size : 10mm x 16mm Brake : disc brake PCD6*44mm Freewheel : single freewheel Net weight : 12 . The German company offers a thoroughly engineered rear hub motor, having acquired Spains Ebikemotion a few years ago. This rests on putting the bearing and the motor through cornering, endurance and durability tests (in accordance with SAE standards J328/2016-03 and J328/2005-2) to see how it sustains loads (reducing their transmission to the rest of the motor), and whether contact in the air gap occurs at any point. The combination of the maximum Hertzian contact stress and the strain corresponding to the maximum allowed air gap deviation yields a specific bearing requirement, called the tilting stiffness, which is typically between 7 and 10 kN/ and which also encompasses extreme cases, Gotovac says. In our standard, publicly known solutions, we construct the rotor with surface-mounted permanent magnets, although we are familiar with other ways of designing and installing the magnets if the application or customer requires their use, Gotovac says. On one such occasion I hit 49 mph, which was too rich for my blood. Our multiphase wave winding helps increase the packing density of copper, which reduces current density across the length of the conductor. Of course, further passive cooling is key, so our windings are potted to help manage the thermal flows that still arise. This makes upgrading your mid-drive motor, even within the same brand, rather difficult. The Japanese cycling component giant was never going to be uninvolved with e-bikes. FSAs rear-hub motor is capable of doing exactly that. At each stage of this approach, we have worked on the basis of analytical equations that have afforded us an insight into holistically optimising our motors designs and dimensions, to meet a broad envelope of performance and environmental requirements as well as other evaluation criteria.. . I note from eg RIversimple that use of super capacitors might greatly enhance regenerative braking as they are nearly instant at accepting incoming charge compared to chemical batteries. Additional simulations of external loads on the L1500, such as those coming from hitting potholes, curbs or other issues related with rough roads, were performed according to SAE standards including SAE J175 and J1981 on impact tests for wheels and tyres in road vehicles. Heres how it works. The Cargo Line is one of the newer Bosch mid-drive motors and has some tidy upgrades. bafang-e.com. Having electric motors instead of gasoline-powered engines makes Teslas able to accelerate far quicker than most standard cars. Privacy Policy. Avidly interested in core EV technologies like motors and batteries, and believes the switch to electromobility definitely should be encouraged. Engineers have managed to do what all riders desire from their mid-drive motors, be lighter and more powerful. The most powerful compact in-wheel motor ever produced. Bosch released a new software update for 2021 to address this, giving more support at low cadences making it easier to set off or ride slowly when carrying heavy loads. Add it all up, and its not hard to understand why EVs dont have in-wheel motors. 1000, Ljubljana The KingSong 18XL is a limited edition version of the KingSong 18L. Protean's PD18 has a crucial advantage over other in-wheel motors - it can be retrofitted to existing vehicles.

These advantages offer OEMs an immediate opportunity to build more unique and functional electric and hybrid vehicles that consumers want and are cost-effective to manufacture. 37" x 18" x 28". Another area could be motorsports. The liquid-cooling circuit constitutes the active cooling of the L1500. Nissan X-Trail e-Power review: Is it better than a Toyota RAV4 Hybrid? The electric motor, code-named the QFM-360-X,. In comparison, the two electric motors used in Jaguar's I-Pace weigh 88 pounds each and deliver just 200 hp. Opting for the hub-drive motor option, FSAs complete e-bike system weighs 3.98kg. The Lightyear One isnt anything like the Lordstown Endurance, but it also features four in-wheel motors. I agree to receive emails from Motor Authority. And in-wheel motors tend to be heavy things. MSRP: $750. Bafang is one of the largest and most well-known electric bike motor companies in the world. Dr. Peter Harrop. And, with a powerful rear-wheel drive 350-Watt motor and large 10-inch inflatable tires, the . For more information, please visit www.in-wheel.com and follow us on Facebook at https://www.facebook.com/ElaphePropulsionTechnologies/. As Lampic notes, every component in each L1500 must be designed for multiphysics efficacy, capable of handling many different kinds of thermal, structural and electrical loads. Please refresh the page and try again. Full-scale production should begin in September 2021, and the company says it's holding 100,000 (non-binding) pre-orders for the big double-cab pick-up truck. In-wheel motors also present the problem of where to put the brakes, which are whats normally found inside a wheel. Hub Motor set: 8356 hubmotor (67KV/1100W)with trucks It is a very responsive system and also includes a power cut off brake system which is a good feature . Which motor to choosea mid-drive or hub motoris one of the most . Furthermore, wrapping wire in this way creates significant overhangs of copper, with strands sticking out from stator teeth (owing to the high number of turns around them) or protruding as they cross from one tooth to the next. Scalability of the companys design processes has been critical for conceiving the structural architecture of each new L1500. DC synchronous modular. Rad Power Bikes' RadRunner Plus is a 20-inch fat tire mini folding electric bike packed full of features and power, enough to take on any job you need. To minimise the effects on the air gap, the bearing must be able to sustain sufficient external loads to prevent them passing through to the rotor and stator. The motor can be mounted in a few orientations, so if you want even higher ground clearance than what you see here, you can do that, too. The AW 26inch Rear Hub Motor Conversion Kit only comes as a rear wheel hub motor with a 7 speed freewheel on a 26 inch wheel. The Bosch Cargo Line also plays nice with both internally geared hubs and traditional derailleur drivetrains. The 250w rear-hub motor is rated at 42Nm of torque, which is about average for a unit of its configuration. As long as you can do those two things, this motor will continue to deliver power to the drivetrain. While theres still some way to go in terms of common, smart standards for inwheel motor development, over the past 20 years weve created a set of internal standards based on our tools, methodologies and various industry best practices.. That is why our measuring stations have been developed internally from scratch, using a combination of industry-standard hardware and software along with our own improvements, to fulfil in-wheel propulsion system requirements while staying compatible with most other systems. Where once the market was dominated by electric bikes for commuting, it is now rich with the best electric road bikes and the best electric gravel bikes as well. Surprisingly simple to install and use, the Bafang 48V 500W Front Hub Conversion Kit is easy on the wallet and your mechanic skills. Elaphes in-house winding machines are optimised to apply each subsequent phase of copper with the appropriate force to insert and compact the bands into the stator slots as deep as necessary for the desired packing density and uniformity, without scratching or breaking them. The only limitation is me, the rider. An OEM in collaboration with Elaphe can select their preferred bearing that fits within these parameters and most existing OEMs and suppliers produce bearings that are suitable.. Theyre simple, energy-efficient and save space, they say. The 5-series motors are very large, and they are also very heavy. The torque output of an electric motor is proportional to the volume of its rotor. Some of those loads acting on the L1500 are internally generated. Home > Features > Elaphe L1500 in-wheel motor. Visit our corporate site (opens in new tab). A single-speed gearbox thats little more than two cogs in a case is used to multiply its lower torque output. Given this need to stay flexible for typical in-wheel motor customers, designing the motors around integrated inverters would have meant driving up design and component costs for each customer. Protean modified the Ford F-150 EV by removing the V8 engine and adding four in-wheel electric motors to the truck. Thank you for signing up to The Pick. The technology allows for complete design freedom and the potential for increased regenerative braking. We have patented this approach, and since then some major OEMs have adopted helical multiphase wave winding, but weve kept developing our automated winding machinery and stator testing procedures. The motor also comes with Walk Assist, which is particularly useful if you need to walk the bike anywhere; it offers a small amount of assistance so it doesn't feel like you're pushing a tank. This category only includes cookies that ensures basic functionalities and security features of the website. All this being said, the company has for more than 10 years now been developing its competencies in integral inverter topologies for in-wheel motors. Lamborghini Urus - 641 Horsepower. An Australian company by the name of HyperPower Technologies has developed an electric motor that generates a mammoth 1,340 horsepower. Where FSA deserves credit, is equipping the motor with a diversity of output sensors: including one for torque and two for speed. This has two critical benefits. The company will begin low-volume series production in the fourth quarter of 2019. Being Elaphes largest and most powerful in-wheel motor yet, the project represented new territory for everyone involved. Torque: 400 Nm. It's been around since 2003, and in 2014 Bafang established a US arm to better support the US. A traditional friction brake, with a disc rotor and caliper, fits inside the stator ring and attaches to the hub, as in all cars these days. He and his team have been working on the dragster and its technologies for the past eight years, and developed many of the parts they used in-house since there was simply nothing on the market. Did I mention you can customize and tune the X1-Pro?

Not having a locked-in inverter also opens up the possibility for reducing costs on a powertrain-wide level. This one does about 100 amps. There are three e-bike classes (Class 4 is for mopeds, scooters, or an electric bike motor with 1000w+). Most of the worlds high-power electric motors are high-speed and medium- or low-torque systems, so most measurement equipment worldwide is designed for those characteristics, Gotovac notes. In 2018 High Power Media launched E-Mobility Engineering as a quarterly magazine focusing on the electric and hybrid vehicle industry, providing concise coverage of the array of engineering challenges presented in this fast-growing market. Then the issues of cost, shock-proofing, brake packaging and unsprung weight also have to be taken into account. Aptera, a startup that's building an ultra-efficient EV, says Elaphe's in-wheel motors offer advantages including enhanced aerodynamics, lower vehicle weight and low energy usage. Now, British carmaker Lotus has introduced a proper, lunch-money . Lawrence Butcher investigates the technology and engineering behind this compact but powerful motor design. Weve analysed most of the leading electric power units available in most contemporary road, gravel and commuter e-bikes. The conductor bands can have a round or square cross-section, as well as a tangential shape to u-bend around each stator tooth to the next, with at least one continuous band per phase of the motor (unlike the many separate bands used in hairpin stators). The companys motor control software has therefore been developed with a modular and common architecture to enable compatibility with varying inverter hardware, as it expects future advances in inverters to rapidly enable higher switching speeds and therefore further improvements in motor control and efficiencies. The latest race content, interviews, features, reviews and expert buying guides, direct to your inbox! These motors power the wheel directly. It is the strongest hub motor available, and can convert any bike into an electric bike. This, combined with a fair price, is sure to make the X1-Pro a staple in the hot-rod e-bike world for years to come. A key challenge with in-wheel motors is how to deal with temperature gradients, Gotovac explains. When taking a broad view of the e-bike technology market, it's interesting to note that mountain bikers still have the option on the most potent motor, TQPs HPR 120S. In-wheel powertrain can also help reduce the overall required battery capacity and cost. Check latest price on E-Wheels 2. Sign up to the E-Mobility Engineering newsletter and stay up-to-date with the fascinating and ever-changing hotbed of innovation. Gallery: Nissan Leaf e+ with dual electric motors and all-wheel drive. For instance, even in a 200 kW test system it is unlikely that a 60 kW in-wheel motor could be tested at its rated or peak torque, because of how a suppliers test benches are built and their corresponding torque-sensing limitations. MORE CAYENNE TURBO GT SPECS Porsche 4. Tesla's next car, the P85D, will have two motors and all-wheel drive. The Japanese motorcycle brand has been experimenting with bicycle pedal-assist systems since 1993.

The L1500 has been designed to enable it to be used in a wide range of OEM EVs and HEVs. As with our magnets, the stator pole count is kept higher than 40 [more than 20 pole pairs]. Any cookies that may not be particularly necessary for the website to function and is used specifically to collect user personal data via analytics, ads, other embedded contents are termed as non-necessary cookies. For magnetic strength, there is always a compromise between the magnet grade and the physical air gap in the motor.. HyperPower said ten of them could be mounted on a common shaft to deliver 13,400 hp. Motor and drive electronics are mounted in a single housing, with the battery. Developed for the Gemera four-seater, this electric motor, dubbed the Quark, is a tiny powerhouse. Saietta claims a 10-kW continuous power output from a 48-V battery. Tesla's most powerful electric Cybertruck comes with triple motor all-wheel drive. "You can optimize your propeller because you don't need an exhaust in the middle of that prop, so that helps a lot," Kist said. The advantage, compared with hairpin stators, is that our overhangs are much shorter, meaning less losses, Gotovac says. Hairpin stators and similar configurations using discrete, short segments of copper conductor bars (rather than strands of wire, or block coils cut from copper foil sheets) can be deformed as needed, to minimise overhangs and maximise the packing density in the stator slots without being damaged. You get a larger wheel without losing portability. The stator ring is made from magnetic steel laminations. 2023 MH Sub I, LLC. First, the stiffness of the customers preferred bearing is characterised using Elaphes in-house numerical analysis software. The companys Turbo Creo SL is powered by a 240w motor and targeted at those road riders who have the fitness, but not the flexibility of schedule for those five-hour training rides. As well as being useful for testing tyres and rims, they are also designed for studying bearings in a fast, repeatable and controlled manner, which is ideal for the L1500. Its 35Nm power output might not be enough for unfit riders who wish to power up the steepest road climbs and retain range, but for fit riders, it is ideal. Like hairpin stator windings, these can be bent into shapes that forcibly pack the copper back into the ferromagnetic core and minimise the degree of overhang outside of it. As Lampic says, We wanted to bring what we feel is required for improving future OEM EV/HEV models. Subscribe to our weekly newsletter! This website uses cookies to improve your experience while you navigate through the website. The latest of those is the CE derivative, specifically engineered for commuter cycling. At the same time in-wheel motors reduce vehicle part count, complexity and cost. After ascertaining the stiffness of the bearing, deformation analysis of the air gap follows. Also, the bands overhangs are pre-formed in a pseudo-helical way, bending perpendicularly and radially relative to the stator slots, to minimise the volume of space they take up and how far they protrude beyond the stator teeth. The X35+ features ANT+ integration and Bluetooth to connect to Mahle's app. And Im also adding a throttle into this review. A single in-wheel motor can achieve a power output of more than 110 kW (147 HP) and fits inside a 19-inch or larger wheel rim. CYC, a small Hong Kong-based company, makes the X1-Pro, a small conversion motor that has an output of about 10 to 20 times that of a typical electric bicycle motor. In parallel with the high-torque requirement, weve constructed them in a way that avoids resonant frequencies when testing motors at very high speeds. Unveiled in 2019, the L1500s design was based in the early stages of its development on the M700. Manufacturers seem to have decided that the solution to packaging occupants and their luggage while providing a range of 450km+ is to adopt increasingly wide skateboards. This is vital, as the development of robust in-wheel electric motors encompasses a far broader set of targets than simply achieving the optimum magnetic fluxes, inductances and other typical electric motor parameters. OEM and international standards in particular have been adapted to cover location-specific environmental and structural load requirements, which differ greatly for in-wheel motors compared with centrally mounted e-axles, as they are usually derived from structural and electrical components that reside in the wheel in ICE-powered cars. 3D CAD: SolidworksMultiphysics tools: Abaqus SimuliaMultiphysics tools: Altair HyperworksCNC machining: Hartford, CNC machining: HeidenhainCNC machining: PinnachoCoordinate measurement: Brown & SharpeAutomated winding machine: in-house, Castings and stampings: MWS and other, undisclosed suppliers, MCU: Inineon TriCoreBraking components: APG and other, undisclosed suppliers, Testing systems: DewesoftTesting systems: Kistler.
