A novel single phase doubly salient permanent magnet motor

In this paper, a single-phase doubly salient permanent magnet (DSPM) motor is discussed. The motor has four stator poles and six rotor poles. Different air-gaps are arranged under stator poles for the purpose of starting. The parking position is in the effective torque zone of the winding. The motor has a simple and robust structure. The principle of operation, modeling and finite element analysis of the motor are investigated in the paper. Experimental results for a prototype machine are also presented.
