Abstract

In this paper, a new disc-type single-phase permanent-magnet motor with a salient pole stator is considered. Due to a particular configuration of the magnets on the rotor disc, the motor develops a starting torque. It also is capable of producing a constant, nearly smooth torque by modifying the current waveform. To determine the required current waveform, the 3-D finite element field model (FEM) is used. To control the current in order to minimize the torque ripple, the field-circuit model of the motor was developed, including the inverter topology.
