Abstract

An improved dynamic model of the switched reluctance machine for use in design has been developed. The specific requirement was for the incorporation of iron losses, but a secondary benefit has been the inclusion of the magnetic interaction between phases. The work is described in two stages: (i) modelling of iron loss and its effect on current waveform in a rudimentary one-phase static SR machine, and (ii) the development of a dynamic model, including instantaneous torque, of a three-phase machine with eddy-current, hysteresis and additional iron losses. Both stages include experimental verification. Coupling between the phases through shared portions of the magnetic circuits and also through ´leakage flux´ is included. Model results are compared with measured values for a three-phase, 12/8-pole motor.
