The Torque Characteristics of the Cycloid Permanent Magnetic Gear Based on Halbach

Abstract:

This paper presents a new cycloid permanent magnet gear(PM gear) based on Halbach array, which has the advantages such as extreme torque density and a very high gearing ratio. And the Halbach array can produce one-sided filed that will increase the magnetic filed intensity. The air-gap magnetic field of cycloid PM gear based on Halbach is got by adopting finite element method. At the same time, to research the torque characteristics, the factors which affect the magnetic torque of cycloid PM gear are studied respectively through the FEM, such as torque angle，offset，thickness of permanent magnets and yoke irons.
