Although Shimano is notorious for its conservative product development, the new EP8 mid-drive motor has been worth waiting for. Elaphe L1500D motor features unique compact packaging around standard knuckles and friction braking systems. Perhaps the better compromise between one or two chassis mounted motors driving differentials is to use four chassis mounted higher RPM motors with (as you say) 2-cog gears driving each wheel (via CV joints to allow for both steering (at front obviously) and wheel suspension bounce (all four). 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. Likes the BMW i3, but it's just too damned wide An excellent analysis of in-wheel motor pros and cons, John. The L1500 D-version in-wheel motor has been optimized for low-volume series production and its earlier versions have been tested on several vehicles including passenger cars and off-road-vehicles. Press Release: Elaphe and McLaren Applied pave the way for highly efficient and hyper-responsive EVs with strategic partnership. Of course, further passive cooling is key, so our windings are potted to help manage the thermal flows that still arise. See Elaphe Christmas video and Happy holidays! FSAs rear-hub motor is capable of doing exactly that. The L1500 has been designed to enable it to be used in a wide range of OEM EVs and HEVs. Get ready to explore the world of mid-drive and hub motor e-bikes as you learn the advantages and disadvantages of each type of motor. 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. Cyclingnews is part of Future plc, an international media group and leading digital publisher. Powerful and adaptable, the Young Electric E-Explorer 1000W Long Range Electric Hunting Bike is ideal for outdoor pursuits like hunting. And two boatbuilders have already . As we see it, the expected trajectory of transistor advances is too fast to commit to one specific technology that we can confidently wrap our motors around, Lampic says. 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. Future Publishing Limited Quay House, The Ambury, It is the world's first 36.5 megawatt (49,000 horsepower) HTS ship propulsion motor. 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 performance of an overclocked motor doesnt feel that much better than this stock version of the X1-Pro. 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. Not having a locked-in inverter also opens up the possibility for reducing costs on a powertrain-wide level. It is mandatory to procure user consent prior to running these cookies on your website. Copyright 2021 High Power Media Ltd All rights reserved. Our multiphase wave winding helps increase the packing density of copper, which reduces current density across the length of the conductor. For example, thermo-mechanical simulations are carried out to examine how the air gap between the rotor and stator might deform as a result of severe heat and shock. Torque: 400 Nm. Installation: 14-50 plug. There are three e-bike classes (Class 4 is for mopeds, scooters, or an electric bike motor with 1000w+). 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. 37" x 18" x 28". Strange business - traction motors for electric vehicles. 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. To accurately predict and assess the motor components structural integrity requirements in the face of especially harsh road-induced loads, Elaphe used an SUV to simulate severe braking and cornering scenarios. the car achieved 3.5 sec 0-100 km/h acceleration time. As with most things in cycling, the issue is differing standards. Which motor to choosea mid-drive or hub motoris one of the most . Rising trend. 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. 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. QSMOTOR 212 10inch 7000W Hub Motor Category: Electric Scooter Hub Motor. HyperPower is the brainchild of Top EV Racing founder Michael Fragomeni. 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. The electric motor, code-named the QFM-360-X, measures about 17 inches in diameter and is designed to be scalable. Available and refined since 2017, the latest upgrade of this rear hub motor launched in late 2020. The controller is integrated inside, as well as a torque sensor that is enclosed in the bottom bracket. Another advanced German mid-drive motor company with a very unique approach. Visit our corporate site (opens in new tab). The company, based in Europe, provides customized and OEM-ready in-wheel powertrain solutions for a wide range of vehicles. The M700 was the first motor Elaphe fully validated according to existing automotive standards, and both motors have some architectural similarities. Images related to this article can be found at https://in-wheel.com/media-gallery/all/. Within 5 minutes the L1500 can be integrated into or removed from a car wheel for routine maintenance, such as brake inspections and replacements. Home > Features > Elaphe L1500 in-wheel motor. Established in 2006 by theoretical physicists Andrej Detela and Gorazd Lampic (now the CEO), its systems incorporate a host of patented and proprietary technologies across mechanics, electromagnetics and other disciplines. This 120Nm motor is not available in a road, gravel or commuter bike frameset. This choice is driven by a range of reasons. 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. In-wheel motor technology offers a fresh solution by providing power that can meet and exceed internal combustion engine alternatives in a package that does not invade chassis, passenger or cargo space. direct-drive wheel hub motor M700. Each has its benefits and pitfalls. Scalability of the companys design processes has been critical for conceiving the structural architecture of each new L1500. These consist of 18 shocks, each measuring 100 g (in force) as well as 60 more shocks of 50 g each. A powerful mid-drive motor designed to haul loads. A key challenge with in-wheel motors is how to deal with temperature gradients, Gotovac explains. We also use third-party cookies that help us analyze and understand how you use this website. 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. 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. An electric motor is an electrical machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. I capped it out at 72V, but I also used a 52V battery to get to my racing destination at an empty track nearby. A unique packaging philosophy without displacing existing packaging and brake architecture. This makes upgrading your mid-drive motor, even within the same brand, rather difficult. In-wheel of wheel-hub electric motors are not a new idea. #2 Addmotor Motan Electric Trike #3 DWMEIGI Adult Electric Trike #4 Liberty Electric Trike #5 Emojo Caddy Pro Electric Trike #6 MotoTec Electric Trike #7 Toxozers Electric Trike #8 Fat. If you need the mindfulness of a big ride, but find yourself constrained by social commitments, the SL 1.1 motor is a great enabler. Using Saietta's own four-bladed propeller, this should produce 3.75 kW of propulsive power. The best e-bike motors will balance the scales between power and weight, to offer maximum pedal assistance without weighing the bike down and holding it back. You get a larger wheel without losing portability. Thank you for signing up to The Pick. The larger vehicle is less prone to small variations that affect balance. The Lordstown factory is building pre-production versions of its first model, the Endurance ute. On September 30, 2021, Hitachi, Ltd. and Hitachi Astemo, Ltd. jointly announced the development of an in-wheel motor for EVs. Has written about cars and the car business for more than 35 years, working full-time and freelance for leading mags, major newspapers and websites in Australia and (sometimes) overseas. As long as you can do those two things, this motor will continue to deliver power to the drivetrain. WALT machines were originally developed to rapidly test and analyse how wheel components would resist damage over their lifetimes. 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. 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). Excess preloading from manufacturing, introduced mostly during machining and casting, can also cause residual internal stresses to build up in motor designs before they are tested. 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. 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. It also has to adhere to tilting stiffness conditions, Gotovac says. Still, some companies are developing four-wheeled EVs with in-wheel motors. 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. Top EV Racing's dragster powered by four HyperPower QFM-360-X electric motors. Both Lightyear and Lordstown stress the benefits of in-wheel motors. 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. Shimano managed to trim 300g of weight from the EP8000 system, whilst making it 10 per cent smaller, too. 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. Its just that none of them are mass-production cars or SUVs. 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. 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. If you turn the center of a wheel, its diameter works as a lever, multiplying the speed at the rim but reducing the torque by the same amount (see our article on how wheels work for an explanation).
