On the dynamic model of a doubly-salient permanent-magnet motor

Abstract

An analytical model has been developed allowing the dynamic performance prediction of a new doubly-salient permanent-magnet (DSPM) motor. The configuration and the operation mode are briefly explained, and the need for a dynamic model is justified. Nonlinear magnetic circuit analysis and finite element calculations are employed for determining the winding inductance and flux linkage. The developed nonlinear description of the DSPM motor dynamics is a basis for a future work on the energy-optimized control of adjustable-speed drives using DSPM motors.
