High Torque Density Torque Motor With Hybrid Magnetization Pole Arrays for Jet Pipe Servo Valve
IEEE Transactions on Industrial Electronics, 2020Torque 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, 2015Magnetic 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.
