Maximum-torque-per-ampere control of high torque-density multiphase drives based on induction motors

2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012
It is known that the torque density of multiphase motors can be increased by superimposing high-order spatial harmonics to the fundamental one in the air-gap magnetic field. However, the problem of maximizing the torque capability is still controversial, since the results depend on the constraints that have been considered.

High Torque Density Torque Motor With Hybrid Magnetization Pole Arrays for Jet Pipe Servo Valve

IEEE Transactions on Industrial Electronics, 2020
Torque motor is one key component that directly influences the dynamic performance of jet pipe servo valve in aircraft. In this paper, a novel torque motor with hybrid-magnetization pole arrays is proposed. By changing the magnetization patterns of permanent magnets, the torque motor can significantly improve the output torque by range of 47–52 ...

A Novel Magnetic Gear: Toward a Higher Torque Density

IEEE Transactions on Magnetics, 2015
Magnetic gears (MGs) are potential alternatives to conventional mechanical gear boxes. With high performance permanent magnets (PMs) and new topologies, today MGs are capable to transmit a torque that is competitive with mechanical gear boxes in a totally contact-free way.
