How far will an eMTB take you on a single charge? In our deep dive, we analyse the maximum range, efficiency and energy consumption of modern eMTB motors.

For most researchers, submitting the first conference paper after earning a doctorate is a memorable moment. For Oak Ridge National Laboratory’s Sangwhee Lee, it was also a winning one. His debut ...

AC induction motors are everywhere, from ceiling fans to vehicles. They’re reliable, simple, and rugged — but there are some disadvantages. It’s difficult to control the speed without complex ...

UK-based Yasa has revealed a potentially game-changing in-wheel electric motor. Based on its record-breaking tiny axial flux motor, the new drive unit prototype can provide over 1,000 hp per wheel.

To achieve EV potential by squeezing more functionality into a given volume, and delivering value at a compelling price point, means there are strong incentives for integrating motor and inverter.

Abstract: The permanent magnets in the rotor of conventional surface-mounted high-speed permanent-magnet synchronous motor (HSPMSM) are vulnerable to centrifugal forces during high-speed rotation, ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...

In the first part of this electrical troubleshooting series, we discussed how a consistent approach to electrical troubleshooting can help HVAC technicians get a comprehensive assessment of what is ...
