EV motor shaft bearings: One of the few moving parts

CoorsTek argues that ceramic bearings are the best fit for EVs The less moving parts in a machine, the better. That’s one often-heard argument for the superiority of electric powertrains over internal combustion engines (ICEs), in which the number of moving components is dramatic. Sure, EVs have a lot of electrons moving this way and… Read more »

ON Semiconductor introduces new power modules for high-voltage EV inverters

ON Semiconductor has released the first two devices within its new VE-Trac family of power modules for high-voltage automotive traction inverters. Future devices in the VE-Trac family will include discrete power devices, isolated gate drivers, and wide bandgap (WBG) devices. The company says its first two devices are ideally suited for use in the main… Read more »

Magna wins DOE grant to develop cheaper EV motor with 8x more power density

The US DOE has awarded a grant to Canadian parts supplier Magna to develop e-motor technologies for next-generation propulsion systems that are both cheaper and more powerful than today’s technology. The supplier has partnered with the Illinois Institute of Technology and University of Wisconsin-Madison for the initiative. The organizations aim to develop an e-motor that… Read more »

Continuous Solutions upgrades its electric motor lab to military grade

Continuous Solutions, a Portland, Oregon-based engineering firm that specializes in the research and development of ultra high-efficiency electric motors, now functions with military grade environmental testing standard.

Audi orders bdtronic impregnation machines for e-motor production

Audi will install e-motor manufacturing equipment from bdtronic, a German mechanical engineering company, for its Premium Platform Electric (PPE) architecture in the coming years. bdtronic manufacturers impregnation equipment, which closes and seals the cavities in windings and coils within hybrid and electric motors to provide better insulation and vibration resistance. Bdtronic CEO Patrick Vandenrhijn said,… Read more »

EuroGroup’s new gluing technology promises to improve motor efficiency and reshape electric machine design

Groundbreaking glue: New results show as much as 44% core loss reductions for the same steel and lamination thickness. Many design decisions in the EV industry are still driven by range. Engineers remain focused on delivering system efficiency improvements, because it directly translates into delivering more range without increasing the size and cost of the… Read more »
