This new X35+ version of Mahles e-bike technology delivers 40Nm of torque output. As a result, Elaphes development models encompass an extensive number of studies, simulations and tests, to iterate a motor that will withstand a broad spectrum of loads over its lifetime. 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. Is waiting patiently for someone to make a good and affordable EV that will fit inside his tiny underground garage in northern Italy, where he's lived for the past decade. The Lohner-Porsche petrol-electric hybrid of 1900, for example, was powered by electric motors built into the hubs of its big, balloon-tyred wheels. 7 million for Elaphe Propulsion Technologies as support from the Slovenian government, Prof. Dr Herbert Kohler, Ex-Tesla Board Member & Daimler VP, Joins Advisory Board of Elaphe. Accurate torque and speed data enables an e-bikes control algorithm to deliver a natural feel, when matching your cadence with some additional watts. Cable length/diameter: 18.7 ft/0.6 in. Class 1 - Includes e-bikes without a throttle and a 20mph max assisted speed. L1500 The most powerful compact in-wheel motor ever produced. As Lampic says, We wanted to bring what we feel is required for improving future OEM EV/HEV models. More specifically, we saw a gap in the market for high-performance distributed drives for electric CUVs and SUVs, sedans, pick-up trucks, people-movers and extremely low energy demand vehicles. 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. 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. As mentioned, defining the optimal bearing was one of the earliest and most important tasks in the L1500s development, in terms of defining the tolerances and optimal design qualities of its various components. They choose smaller motors that can easily spin to more than 10,000rpm. 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. 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. So, while in-wheel motors may save some space, their advantage isnt as clear-cut as it might first appear. Slovenian company Elaphe is known in the e-mobility industry for its in-wheel propulsion technology, which is used in a range of automotive applications around the world. WALT machines were originally developed to rapidly test and analyse how wheel components would resist damage over their lifetimes. This 120Nm motor is not available in a road, gravel or commuter bike frameset. 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. In-wheel motors aren't new. With a mid-drive motor, you are stuck with what you have. In terms of ride feel, the PW CE delivers a natural-feeling ride. This motor is the culmination of my careers effort and a notable milestone for our team to now have the (motor) in production, with volume assembly running in parallel, he said. Another area could be motorsports. The Elaphe distributed propulsion architecture is the ultimate propulsion solution for connected and automated vehicles, bringing new opportunities to mobility and transportation. 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. 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. Most electric bikes I ride feature a motor in the range of 250W to 1,000W. 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. With a well-made electric motor from the likes of Bosch or Yamaha, even a 250W motor can deliver. Following static testing, fatigue tests are performed to simulate the effects of multiple loads over the service life of the motor, and to see how many repeated loads the motor could take before its components finite elements begin showing signs of deterioration. This is because most electric bicycles are trying to mimic the feeling of a bicycle, which makes total sense. The stator ring is made from magnetic steel laminations. Dr. Peter Harrop. Elaphe therefore anticipates considerable customisation and differing production cycles for each motor. Sponsored. Each of the four Protean Drive motors are capable of delivering over 100 hp each, a total of 400 hp from all four motors -- far more than produced by the standard V8 engine. The result is a compact mid-drive motor that delivers 50Nm of torque output, which is entirely adequate for any inner-city gradient you might have to ride up. Installation: 14-50 plug. First, the stiffness of the customers preferred bearing is characterised using Elaphes in-house numerical analysis software. With over 700 Nm of peak torque, 75 kW of peak power and . Of course, e-bike motors come as part of the bike itself and aren't yet a component that you can swap out and upgrade, so it's important to know what you're getting into when choosing from the best electric bikes. Other proprietary innovations have been developed to help balance the voltages between parallel branches in each phase, to accelerate automated production of large volumes of copper (while packing them more densely), and to make the winding more robust against high temperature gradients not just extremes of temperature, but rapid changes in short periods of time. 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. These cookies will be stored in your browser only with your consent. With more experience and our model accuracies optimised, we replaced the N40UH with N40SH, the latter being in the 150 C temperature class.. Attendees of the expo can learn more about the technology at booth #324 at the Stuttgart Expo where Elaphe personnel will be on hand to provide an overview and answer other questions. 1000, Ljubljana GoTrax GLX V2. Then the issues of cost, shock-proofing, brake packaging and unsprung weight also have to be taken into account. You get a larger wheel without losing portability. 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. It will match the 3.2 second 0 to 60 mph time of the McLaren F1, one of the fastest cars ever made. You can switch out the stock controller, rated for 65 amps, and easily swap in an ASI BAC800, which has a higher rev range. Basically, they add to the weight that has to be controlled by the suspension systems shock absorbers. Being Elaphes largest and most powerful in-wheel motor yet, the project represented new territory for everyone involved. Until today, the world's most powerful production car was the all-electric Rimac C_Two, which makes a puny 1,914 horsepower. Most electric bikes I ride feature a motor in the range of 250W to 1,000W. This inescapable relationship means in-wheel motors need big rotors to make enough power to deliver customer-satisfying performance. Control Electronics Design and Validation, The L1500 motor is compatible with all drive layouts. 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. For all the benefits of e-bikes, they can also create confusion and ownership anxiety, triggered by the steep technology curve powering these bikes along. In-wheel motors have a tough life. 37" x 18" x 28". 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. All fine in the US but European garages and villages were never designed for these vehicles. 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 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. You will receive a verification email shortly. 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. With the SL 1.1 motor, Specialized has shown how light a high-performance road e-bike can be. Its just that none of them are mass-production cars or SUVs. 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.
