For example, an EV designer could choose to have a dual-inverter integration in a single housing, which could use a singleloop cooling system, share a single logic board, faster comms for full axle control, and so on, Gotovac says. Its what we call our multiphysics approach, says Lampic. At the same time in-wheel motors reduce vehicle part count, complexity and cost. However, wire strands can suffer significant damage as a result. Maybe Lordstown, Lightyear and others will change the situation, but it seems unlikely theyll change the minds of manufacturers using chassis-mounted motors with reduction gears and differentials. Examples of these are thermo-echanical stress due to excess heat from electromagnetic losses in the copper windings, steel laminations and permanent magnets, and frictional losses in the bearings and seals. Lance Branquinho is a Namibian born media professional, with 15-years of experience in technology and engineering journalism covering anything with wheels. Subscribe to Electrek on YouTube for exclusive videos and subscribe to the podcast. DC synchronous modular. And, with a powerful rear-wheel drive 350-Watt motor and large 10-inch inflatable tires, the . Approving a bearing for the L1500 requires a measure of special attention. With a differential, the motor can power two wheels. See Elaphe Christmas video and Happy holidays! One, by maximising the cooling surface, we achieve the highest potential torque densities possible. This 120Nm motor is not available in a road, gravel or commuter bike frameset. Then the issues of cost, shock-proofing, brake packaging and unsprung weight also have to be taken into account. Powerful and adaptable, the Young Electric E-Explorer 1000W Long Range Electric Hunting Bike is ideal for outdoor pursuits like hunting. Thermal sensors are added to the bearing hub during these tests to measure any overheating. This motor is compatible with 36, 48, 52, or 72V, just drop it right in, and the motor knows what to do.

While normal bearing deformations arent a major problem, excessive deformations in an in-wheel motor can cause deflections between the rotor and stator. 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 electric motor, code-named the QFM-360-X, measures about 17 inches in diameter and is designed to be scalable. Elaphe has therefore developed a regime for validating the stiffness and durability of bearings before it will integrate them into the L1500 (or its other in-wheel motors). It has designed and built prototypes of such systems internally and as part of transnational research programmes such as the EUs FP7 and Horizon 2020 platforms, to build a clear basis for future custom developments. Also, it is generally similar, but not the same, as the battery electrical "horsepower" output. 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. The German company offers a thoroughly engineered rear hub motor, having acquired Spains Ebikemotion a few years ago. 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. Though regenerative braking can do much of the work of slowing down an EV, for safety reasons they also need to be equipped with friction brakes. For more information, please visit www.in-wheel.com and follow us on Facebook at https://www.facebook.com/ElaphePropulsionTechnologies/. Until today, the world's most powerful production car was the all-electric Rimac C_Two, which makes a puny 1,914 horsepower. Home > Features > Elaphe L1500 in-wheel motor. I think Lotus did some research on the unsprung weight issue and concluded it was a matter for good suspension design and not a no-no, but certainly the environment to which an in-wheel is subjected is not great. These cookies do not store any personal information. The ideal candidate will be a $400 mountain bike with 26 inch wheels and cable pull disc brakes. The low motor mass also makes Specializeds SL1.1. $430.99. Being from Namibia, he knows a good gravel road when he sees one, and he has raced some of Africas best-known mountain bike stage races, such as Wines2Wales and Berg&Bush. Specializeds idea with the smaller SL 1.1 motor is to allow riders to ride a great distance, with ample gradient, in much less time. Some of those loads acting on the L1500 are internally generated. Max power: 9.6 kW. Also, NVH (noise, vibration and harshness) simulations provide insight into a critical part of inertial load testing. As with most things in cycling, the issue is differing standards. Most electric bikes I ride feature a motor in the range of 250W to 1,000W. Peak power is an impressive 85Nm, up from 75Nm, and it operates to a maximum cadence of 120rpm, making the Bosch Cargo Line ideal for hauling goods (or kids) up a steep incline. Opting for the hub-drive motor option, FSAs complete e-bike system weighs 3.98kg. The X35+ features ANT+ integration and Bluetooth to connect to Mahle's app. After examining where the earliest deteriorations appear, the design loop is (where necessary) executed again from the start in order to optimise the chamfers, radii and other small shapes and details of the components before actual fabrication. 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. 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). 6) Wheel Size: 17 x 6.0 inch (Aluminum Wheel) 7) Recommendation Tyre: 180/55-17 to 220/70-17. 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. "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. Something of the new kid on the block in the world of . And Im also adding a throttle into this review. Bosch-made in-wheel motors are popular in small electric motor scooters, like those produced by the Chinese brand Niu. 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. Media and interview requests can be directed to:Elaphe media contact, Luka Ambrozicpress@elaphe-ev.comWebsite:www.in-wheel.comMedia gallery:https://in-wheel.com/media-gallery/all/, Teslova 30 The L1500 D-version in-wheel motor has been optimized for small-series manufacturing. Theyre subjected to the same shocks and stresses as the wheel itself. How good is it? Wilier. The potting material is a custom epoxy resin formula developed to meet requirements such as heat transfer, crack resistance, electrical resistivity, production cycle times and other process-related aspects.. The Evation drive system features a bottom-bracket-mounted gearbox, which benefits from data sensors on both sides. This helps it to optimise ambient cooling, even at low speeds. You can switch out the stock controller, rated for 65 amps, and easily swap in an ASI BAC800, which has a higher rev range. The motors aluminium rotor case contains the yoke and permanent magnets, the case wraps around the stator, and is connected to the vehicle knuckle by a conventional automotive wheel hub bearing. Its poles use a patented winding method developed in-house, and it attaches directly to the vehicle knuckle. Brushless DC Motors: 6374 /6354/ 5065 /5055 motor kit 2. This one does about 100 amps. GoTrax GLX V2. Gallery: Nissan Leaf e+ with dual electric motors and all-wheel drive. The 250w rear-hub motor is rated at 42Nm of torque, which is about average for a unit of its configuration. 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. It might weigh less and be more compact, enabling better frame integration, but the Shimano EP8 is 10Nm more potent than its EP8000 predecessor, delivering 85Nm of output. In relative terms, far fewer wire connections need to be made, which improves consistency of quality, reliability and production costs. It also has a torque-to-weight ratio of 100 Nm/kg; its competitors go up to 65 Nm/kg, Elaphe says. FTC: We use income earning auto affiliate links. Images related to this article can be found at https://in-wheel.com/media-gallery/all/. Its 6.2-liter supercharged V-8 is the most powerful. After ascertaining the stiffness of the bearing, deformation analysis of the air gap follows. 1000, Ljubljana The stator ring is made from magnetic steel laminations. An electric generator is mechanically identical to an electric motor, but operates with a reversed . The number of magnets we install varies but is quite high, usually exceeding 40 on the L1500. Weighing in . Another area could be motorsports. Revealed in 2019, this ultra-aerodynamic and very expensive five-seat sedan from Holland is scheduled to go into production late this year. 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. Class 1 - Includes e-bikes without a throttle and a 20mph max assisted speed. Combining those two aspects makes our measuring stations uniquely universal in their ability to test motors of widely different types and characteristics, while complying with automotive standards.. According to a 2021 report from research firm Markets and Markets, the demand for in-wheel motors is expected to rise in line with the growth of electric vehicle sales, reaching a . The latest race content, interviews, features, reviews and expert buying guides, direct to your inbox! Targeted at e-bikes for the road, gravel and commuter applications, packaging was a crucial parameter within FSAs engineering goals. These must instead be transmitted through the rim and bearing and into the knuckle (before continuing on to the vehicle chassis). This is because most electric bicycles are trying to mimic the feeling of a bicycle, which makes total sense.. Those standards have also informed our requirements for e-motor and inverter-specifi c performance parameters, EMC, electrical safety, durability and cable routing. The described assembly of rotor, stator, brakes and bearing transfers loads from the road (which will vary depending on vehicle weight, braking dynamics, cornering and ground roughness) directly to the vehicle knuckle via the bearing, protecting the electric motor components from such impact loads. The Quark electric motor, from Koenigsegg, is the latest. The bearing is selected as a function of the wheel loads stemming from the vehicles weight, its CoG, wheelbase, track width and maximal lateral acceleration achieved during cornering. Volvo Construction Equipment. There was a problem. Starter motors are still typically the most powerful electric motors other than traction motors. For example, in lap winding, each continuous strand of conductor wire can be damaged as it is inserted into and twisted around the stator teeth. Yamaha markets a variety of e-bike motors for all applications, as part of its PW product line. . Even with these added components, a chassis-mounted electric motor assembly is a remarkably compact thing. More. Elaphe previously showcased prototype mules based on the Smart ForTwo, BMW X6 SUV and Audi R8 platforms, among others, demonstrating proven applications for direct drive, in-wheel propulsion motors. 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. Rising trend. Before iterating the key aspects of a new L1500s design through CAD simulations, Elaphe first selects the key peripheral components (including the rim, brakes and bearings) in order to define how much space is left for the stator and rotor. The Endurance has The Worlds First All-Electric In-Wheel Drive System Built For Work, according to the capital-letter enthusiasts in the Lordstown marketing department. As one of the best electric cars for kids on the market, the GMC Sierra Denali pickup can hold up to 62 lbs in its cabin, and its dimensions are slightly larger than other, more compact children's cars at 53 (L) x 33.5 (W) x 29 (H). The Lohner-Porsche electric car of 1901 used in-wheel electric motors The Lordstown factory is building pre-production versions of its first model, the Endurance ute.
