Static Characteristics of Doubly Salient Permanent Magnet Motors for Adjustable Speed Drives

The magnetic field and the flux density in the airgap of a doubly salient permanent magnet motor at no load,one phase on and two phase on conditions are analyzed in detail by using two dimensional finite element method.Hence,the corresponding static characteristics including PM flux linkage,self inductance,mutual inductance and back EMF are deduced.The effect of the cross coupling between permanent magnet field and armature field are taken into account.The validity of the theoretical analysis is confirmed by the experimental results on a prototype machine.
