Abstract: The torque density of a multiphase motor can be increased without exceeding the admissible current of the drive if the high-order spatial harmonics of the magnetic field in the air gap are ...

Brushless motors offer greater efficiency, durability, and speed control compared to brushed motors used in pump systems.

Texas Instruments is developing GaN power devices to enable more compact and efficient motor joints for humanoid robots.

Abstract: The rotor eccentricity and manufacturing tolerances caused by unavoidable uncertainties in the process of manufacturing deteriorate the cogging torque of permanent magnet (PM) motors. To ...
