Abstract :
Static and dynamic core loss tests for a synchronous reluctance machine are reported. The effect of inductance ripple has been found to increase the actual losses apparent under specific flux and frequency conditions. Using curve fitting, a simple core loss model has been derived from experimental data. This model has been used to compare the steady state performance of constant current angle and constant flux control strategies using a DSP controlled drive system. The constant current angle strategy displays an efficiency advantage over a significant portion of the base speed operating range,
