Abstract

A time stepping finite element modelling technique, which can accurately represent the single-phase synchronous motor with a permanent magnet rotor, is presented. The modelling allows the rotor to move with respect to the stator at each time step, and the spatial angular step is determined by the solution of the equations of motion and the computed electromagnetic torque. The model is voltage driven and no restriction on the time variation of the applied voltage is imposed. The magnetic nonlinearity of the stator iron is taken into account in the field equations describing the electromagnetic field of the motor
