Abstract

Abstract

A flux focusing magnetic gear with Z-type pole-pieces (ZP-FFMG) was presented and investigated. In this magnetic gear structure, the proposed Z-type pole-pieces can couple the magnetic flux of the end face and cylindrical face of rotors. The 3D simulation shows that there are axial and radial magnetic flux components in the ZP-FFMG, which are helpful to torque transmission. A comparative analysis of traditional flux focusing magnetic gear (FFMG) and ZP-FFMG was given. The results show that compared with the traditional FFMG, the transmission torque of the ZP-FFMG is increased by 42%, the torque density is increased by 15 kN·m/m³, and the magnetic flux density is also improved.
