Effect of relative phase-shift of magnetic field axes on armature reaction and performance of Hybrid Permanent Magnet Induction Machine

摘要

In this paper, the effect of variation of angle between the magnetic field axes of armature field and PM rotor field on armature reaction and performance of a Hybrid Permanent Magnet Induction Machine (PMIM) is presented. The variation of resultant air gap flux density and torque-slip characteristics of the machine for different angle between the magnetic field axes were obtained using Finite Element Method. The comparative analysis of the results portray a method to achieve variation in the air gap flux and torque of the machine.
