The e-bike motor is integral to the frame and cannot be easily swapped like other components, so here's everything you need to know before you buy your next electric bike. The electric motor, code-named the QFM-360-X, measures about 17 inches in diameter and is designed to be scalable. This helps it to optimise ambient cooling, even at low speeds. 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). Theyre subjected to the same shocks and stresses as the wheel itself. 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). 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. Using Saietta's own four-bladed propeller, this should produce 3.75 kW of propulsive power. Motor and drive electronics are mounted in a single housing, with the battery. Bosch engineers have meticulously engineered the Cargo Lines casing, paying special attention to surface area and shape. Thats also helped refi ne our proprietary processes for how to make the windings as short as possible.. The Elaphe distributed propulsion architecture is the ultimate propulsion solution for connected and automated vehicles, bringing new opportunities to mobility and transportation. Hub Motor set: 8356 hubmotor (67KV/1100W)with trucks In comparison, the two electric motors used in Jaguar's I-Pace weigh 88 pounds each and deliver just 200 hp. In-wheel motors also present the problem of where to put the brakes, which are whats normally found inside a wheel. With an integrated standard disc brake, a standard outer caliper and a standard hub bearing, it is designed to fit the original vehicle knuckle due to an innovative packaging concept. In addition to being able to customise the in-wheel electric motor for carmakers preferred brake and bearing suppliers, the L1500s performance and components can also be tailored to meet manufacturers application-specific requirements. Accurate torque and speed data enables an e-bikes control algorithm to deliver a natural feel, when matching your cadence with some additional watts. 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. Patented and innovative electromagnetic and mechanical designs for in-wheel propulsion enable Elaphe products to be tailored for specific ranges of torque and horsepower to fit most vehicle configurations. 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. QSMOTOR 212 10inch 7000W Hub Motor Category: Electric Scooter Hub Motor. An Australian company by the name of HyperPower Technologies has developed an electric motor that generates a mammoth 1,340 horsepower. The most notable features of Elaphes in-wheel motors are their extremely high torque, low weight and unique, compact packaging around standard knuckles and friction braking systems. Thoughtful article John. 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. It is the world's first 36.5 megawatt (49,000 horsepower) HTS ship propulsion motor. The stator ring is made from magnetic steel laminations. So, while in-wheel motors may save some space, their advantage isnt as clear-cut as it might first appear. Another issue is that in-wheel motors add to what engineers call unsprung weight. 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. The Protean Drive. With more experience and our model accuracies optimised, we replaced the N40UH with N40SH, the latter being in the 150 C temperature class.. With a top speed of 186 mph, the Cayenne Turbo GT is the lightest, most powerful gas-only Cayenne ever built. The new Ampere motor weighs less than 10 kg (22 lb) and makes a whopping 220 kW . Which flux type are our motors radial or axial flux? Rider research showed that Boschs engineers had to improve the low-speed cadence matching of their Cargo Line motors. 17inch 12KW Hub Motor 1) Motor Type: DC Brushless Motor. 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. So perhaps the next article should be Why dont EVs have four near-wheel motors? with Yeh, why not! added! For the utmost effortless journey, you need to install a powerful e-bike conversion kit. British company Equipmake has used 3D printing to radically boost power-to-weight figures for its electric motors. For broader and closer accuracy of how the bearing will behave over its lifetime, Elaphe then conducts experiments using the Wheel Accelerated Life Test machine (WALT) at the Fraunhofer LBF Institute for Structural Durability and System Reliability in Darmstadt, Germany, with additional similar tests locally on dedicated deflection measurement benches. As packaging and cooling requirements change with different inverter technologies and topologies, having the inverter on the vehicle chassis means it can be swapped out relatively easily, compared with trying to force an entirely new inverter into the old ones space. Future Publishing Limited Quay House, The Ambury, How good is it? 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. A disadvantage is that instead of sophisticated cadence sensors, the Mahle system requires a torque conversion sensor between the rear hubs rotational speed and cassette motion, to calculate and initiate assistance. There is no tightening or straining of them, as might happen with copper strands, or any post-deformation as with hairpin stator conductors. In recently performed track testing of the L1500 in-wheel powertrain in a modified electric prototype vehicle, Images related to this article can be found at. In most electric cars, the motor is found on one axle and in four-wheel drive cars there will be two motors, one on each axle. The L1500 motors are therefore simply inserted between the electric [or hybrid] vehicles hubs and rims, which makes use of the existing space within the wheel without needing to alter any suspension or steering packaging on the platform, explains Elaphes CTO Gorazd Gotovac. Grew up in country NSW, way back when petrol was laced with lead. Protean Electric PD18 in-wheel motor. Electric motors are much more efficient at driving wheels than internal-combustion engines, and in the case of Top Fuel dragsters, the cars running over 5,000 hp are slipping the clutch for half their runs, according to Fragomeni, meaning they're not using the full power they're making. At 637 horsepower in launch control mode, Audi says that the RS e-tron GT is the most powerful vehicle they've ever produced, gas or electric. 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. 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. Elaphe is a global Tier 1 supplier for light-weight, high-performance in-wheel motors and provides the highest documented torque density for in-wheel electric vehicle technology in the world. But there's a snag: in electric bikes, they sit inside the hub, at the very center of a relatively large, spoked wheel. The German company offers a thoroughly engineered rear hub motor, having acquired Spains Ebikemotion a few years ago. Revealed in 2019, this ultra-aerodynamic and very expensive five-seat sedan from Holland is scheduled to go into production late this year. Sign up to the E-Mobility Engineering newsletter and stay up-to-date with the fascinating and ever-changing hotbed of innovation. Youre an adult, you can figure this out for yourself. 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. This changes the shape of the air gap, which causes vibrations as well as loss of efficiency owing to the increasing resistance to magnetic flux between windings and magnets where the gap widens, and decreasing flux resistance where it shrinks. Targeted at e-bikes for the road, gravel and commuter applications, packaging was a crucial parameter within FSAs engineering goals. It also has a torque-to-weight ratio of 100 Nm/kg; its competitors go up to 65 Nm/kg, Elaphe says. Protean CEO Andrew Whitehead and Chief Commercial Officer Ben Boycott sit down with Auto Futures to speak about the development of the world leader of in-whe. 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. Class 2 - Electric bikes with a throttle and a max speed of 20mph. Riding this fast is indeed scary and thrilling, but oddly enough, I somehow feel safer using the X1-Pro motor, because I know its made for high speeds. And Im also adding a throttle into this review. LEITNER and Elaphe on Connx: intensive testing and development phase as a major step towards market readiness, Elaphe on DREEM e-motor design and prototype tests, Aptera and Elaphe ink deal for scale production, Elaphe and Lightyear develop the most efficient production powertrain in the world, The fat ballerina on winter testing grounds, ASTRABAT applies certifications to all-solid-state battery prototype. With a well-made electric motor from the likes of Bosch or Yamaha, even a 250W motor can deliver. The Lordstown factory is building pre-production versions of its first model, the Endurance ute. Engineers have managed to do what all riders desire from their mid-drive motors, be lighter and more powerful. England and Wales company registration number 2008885. Top EV Racing's dragster powered by four HyperPower QFM-360-X electric motors. However, most of its systems are designed to operate with the inverter on the vehicle chassis rather than inside the wheel housing. 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). It also comes with an integration of EPB. These motors power the wheel directly. Surprisingly simple to install and use, the Bafang 48V 500W Front Hub Conversion Kit is easy on the wallet and your mechanic skills. Having electric motors instead of gasoline-powered engines makes Teslas able to accelerate far quicker than most standard cars. This has two critical benefits. For . But shoot, aint no one using a 36V battery with this! A Bafang Ultra mid-drive motor on a QuietKat JEEP all-terrain electric fat bike. This is because most electric bicycles are trying to mimic the feeling of a bicycle, which makes total sense.. 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. 4) Voltage Range: 72V, 84V, 96V, 108V, 120V. The advantage, compared with hairpin stators, is that our overhangs are much shorter, meaning less losses, Gotovac says. 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. Cars on the road expect motorcycles to be fast and loud, and they have bigger lights and safety features. 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. 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. HyperPower said ten of them could be mounted on a common shaft to deliver 13,400 hp. The electric motor, code-named the QFM-360-X,. To ensure each motor provides precise and reliable performance over its lifetime, regardless of differences between vehicle chassis and complementary parts, Elaphe has a rigorous set of design requirements, simulations and testing processes. The Swedish hypercar outfit has unveiled the mighty mite as locomotion that will help drive its plug-in hybrid Gemera sedan. Ive got it equipped on a Specialized hardtail. It is a very responsive system and also includes a power cut off brake system which is a good feature . The FSA System HM 1.0 is an integrated approach. 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. 85 percent of the available kinetic energy in the Protean Drive can be recovered during braking.The motor does not require external gearing, drive shafts, or differentials. The cooling medium is typically a waterglycol 50:50 mix, as commonly used in other traction motors. The torque output of an electric motor is proportional to the volume of its rotor. About Elaphe Propulsion Technologies The low motor mass also makes Specializeds SL1.1. TAX ID: 68995792. also, it can cover a range of up to 804+ KM ( 500+ miles) on a single full charge. When you purchase through links on our site, we may earn an affiliate commission. 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. That keeps them small in size and has some very positive effects in terms of reducing eddy-current losses and their overall mass relative to the magnetic flux., Neodymium is used for the L1500s permanent magnets, a material selection which has also been motivated by the need for high torque density. Did I mention you can customize and tune the X1-Pro? In general, our testing strategy is based on three factors testing based on OEM and international standards, then legislation, and lastly, internally identified tests based on design failure mode and effect analysis exercises, vehicle tests and simulations, Lampic says. This isn't the most powerful electric unicycle out there, but if you wish the V8 offered just a little more, the V8F is the better choice. The number of magnets we install varies but is quite high, usually exceeding 40 on the L1500. Wherever possible, Elaphe has sought to minimise the L1500s weight. The company is developing their system as the ultimate platform for the future of electric vehicles. This allows for a very balanced delivery of power assistance and seamless disengagement when pedalling beyond the motor's speed limit. At the beginning of the 20th century, Ferdinand Porsche's first hybrid vehicle used hub-mounted electric motors in each wheel. You also have the option to opt-out of these cookies.

This makes upgrading your mid-drive motor, even within the same brand, rather difficult. (adsbygoogle = window.adsbygoogle || []).push({}); Surprisingly, the motor is easy enough to install, has a clean form factor, and encourages customization by design. As a heavily laden touring bike motor, it also makes a great deal of sense. With a differential, the motor can power two wheels. 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. The equipment enables rapid iterations and confirmations of product designs, although the company also cooperates with various institutions around the world for impartial third-party validations and to complement its own efforts. Our method means maybe only 24 welds or so are needed for each L1500 stator..
