Nidec adds 100 kW and 70 kW models to E-Axle lineup

Japanese electric motor company Nidec has developed two smaller versions of its fully-integrated traction motor system, E-Axle. It has also announced a new short-range radar that doubles as a proximity sensor for automatic parking systems. Nidec first introduced the E-Axle system in April 2018 as a 150 kW system, composed of an integrated electric motor,… Read more »

DOE to offer $59 million for advanced vehicle technology research

The DOE has announced $59 million in new funding for research on advanced vehicle technologies, including advanced batteries, electric drive systems and materials for more efficient powertrains. Funding opportunities fall within six topic areas. Those directly related to EVs include: Solid State Batteries – Up to $12.5 million available for projects aimed at developing new solid electrolytes. Projects should address… Read more »

Linear Labs raises $4.5 million to market its electric motor

Electric motor manufacturer Linear Labs has closed a $4.5-million funding round to market its flagship motor, the Hunstable Electric Turbine. The Hunstable Electric Turbine uses multiple rotors. Compared to available permanent magnet motors, Linear Labs’s motor produces twice the torque, three times the power density, two times the output and 10 percent further range, according… Read more »

93% of EVs sold in 2018 used permanent magnet traction motors

Research firm Adamas Intelligence has reported that 93 percent of all passenger EVs sold in 2018 used permanent magnet (PM) traction motors, an increase of 1 percent from 2017. PM traction motors use neodymium iron boron (NdFeB) permanent magnets in the rotor, which spin the rotor in response to a rotating magnet field produced in… Read more »

Nidec announces in-wheel motor prototype

Motor manufacturer Nidec has announced a prototype for an in-wheel EV traction motor. The company aims to begin mass production of the motor around 2023. The prototype motor fits within the wheel hubs of an EV, a design which Nidec claims allows for higher efficiency and lighter, more compact designs than motors occupying the engine… Read more »

ELANTAS increases electric motor longevity with nanoparticle-infused insulation

Protecting against dielectric fatigue Like the engines in conventional vehicles, the electric motors in EVs are designed for longevity, but every device will wear out eventually. While motors have many fewer moving parts than ICEs, they are under considerable electrical and mechanical stress. A properly designed electric motor should have a useful life that far… Read more »

A closer look at the losses in EV motors

  In the bad old days when the only batteries suitable for traction applications were flooded lead-acid and Ni-Cd types, the battery was the least efficient component of an EV powertrain, routinely delivering back only 50-70% of the amp-hours that went into charging it (aka the Coulometric efficiency). When you knew you were going to… Read more »

Freudenberg introduces new testing tools for high-rpm seals in electric motors

Freudenberg Sealing Technologies has introduced several specially-designed test stands to measure frictional torque in shaft seals used in electric motors. The stands, which are located in its Weinheim test facility, can measure at rotational speeds up to 36,000 rpm. Freudenberg says that seals used between electric motors and downstream transmissions must withstand higher speeds and… Read more »
