Electromagnetic Design of a New Electromagnetic Planetary-Gear Machine

Abstract:

A novel brushless compound-structure permanent-magnet synchronous machine (CS-PMSM) based on the magnetic field modulation principle is proposed for hybrid electric vehicles. As the key part of the brushless CS-PMSM, the operation principle of the electromagnetic planetary-gear machine (EPGM) is investigated by analytical method. The magnetic-field distribution and torque performance of the EPGM are studied by finite-element method (FEM). To obtain the optimal design scheme, the influence of the span ratio and thickness of the magnetic block and the slot-opening on the electromagnetic performance is investigated. Finally, the core loss distribution of the EPGM is investigated and the performance of this machine is fully evaluated.
