OEMs, tier ones evaluate compact electric motor from Israeli startup

Over 15 global vehicle manufacturers and Tier-1 automotive companies in eight countries will conduct evaluations of high-performance electric motors developed and manufactured by EVR Motors in Israel. The novel motors are less than half the size and weight of existing state of the art RFPM (Radial Flux Permanent Magnet) motors with similar power. After extensive testing of the prototype of its motor, EVR is building dozens of pre-production motors to deliver to customers for evaluation. The company is also developing additional motors and setting up an assembly line in Israel, in order to enable its customers to enter series production from the second half of 2022.

EVR is in process of partnering with unnamed Tier-1s and OEMs interested of manufacturing  and marketing motors developed by the Israeli company. EVR will tailor the motors according to performance, size, cost, and other requirements of each specific customer. Customers not interested in manufacturing motors can be supplied with motors manufactured by EVR or its partners, including motors deigned to meet their specific requirements.

“Electric vehicle sales will outstrip all other engines five years sooner than previously expected, according to recent research by Ernst & Young,” noted Opher Doron, CEO of EVR Motors. “Vehicle manufacturers want electric motors with less size, weight and cost, which provide more power, efficiency and flexibility – and this is exactly what we are providing. We decided to respond to market needs by reimagining electric motors and developing our patented TS-RFPM topology. The breakthrough electric motor we unveiled in May 2021 witnessed tremendous interest from OEMs, Tier-1s and potential partners. Now, we are increasing the momentum by helping multiple automotive companies evaluate the motor and see for themselves how it can transform the industry.”

EVR’s first two/three-wheeler air-cooled 48/96V motor provides a peak power of 17kW and peak torque of 41Nm, yet weighs only 9 kgs, with a volume of 2.7 liters. EVR can provide multiple variants of the 2/3-wheeler motor, whose testing has already been successfully concluded.

The company is developing additional motors, including a water-cooled version of its first motor, that will supply 35kW power, alongside a very small 6.5 kg, 7-9 kW electric motor for two-wheelers, plus a water-cooled 400V electric motor for passenger cars and light commercial vehicles.

The new electric motors are based on EVR’s patented TS-RFPM (Trapezoidal Stator Radial Flux Permanent Magnet) topology, which provides improved performance, while at the same time maintaining the advantages of traditional RFPM motors. The motors generate higher power for their size thanks to increased flux, high fill factor, superior copper utilization, heat dissipation and thermal capacity. The novel topology provides significant reduction in cost as a result of lower Bill of Materials (BOM) and production costs, along with a simple assembly process.

EVR Motors will target most mobility and industrial applications, including two and three wheelers, passenger and light electric vehicles, trucks, busses, Battery Electric Vehicles (BEVs), Hybrid Electric Vehicles (HEVs), Plugin Hybrid Electric Vehicles (PHEVs), Mild Hybrid Electric Vehicles (MHEVs), golf carts, forklifts, trains, boats etc. TSRF technology can support a wide range of power and torque outputs, with voltage ranging from 48V to 800V, that are suitable for different power levels and for a wide range of speeds.

The company is led by CEO Opher Doron, who in the past held senior positions at Israel Aerospace Industries (IAI), Israel’s largest aerospace firm. In his former role as General Manager of IAI’s Space Division, Doron was responsible for the development, construction, launch, and operation of observation and communication satellites for Israeli and foreign users and led the IAI team in designing and constructing SpaceIL’s Beresheet lunar lander.

 EVR Motors is backed by a team of investors, led by Marius Nacht, one of Israel’s leading serial entrepreneurs, tech founders and investors. Teramips Technologies, which funds innovative technical ideas, is another key investor. Additional funding has come from Varana Capital and SIBF (South Israel Bridge Fund VC) and through grants from the Israel Innovation Authority.
