Abstract

This paper proposes a new 8/6-pole split-winding doubly salient permanent magnet (DSPM) motor drive. The analysis, control, implementation and experiments of the motor drive are presented. The magnetic field analysis is carried out using finite element method. The split-winding topology is proposed to extend the constant power operation range. The control strategy for the DSPM motor drive is developed. Two operation modes, namely 4-phase and 2-phase operation modes, are proposed for the 8/6-pole DSPM motor drive. In 4-phase operation mode, a half-bridge power converter but without split capacitors is used to reduce the number of power devices and to eliminate the problem of voltage unbalance in the capacitors. The drive system is implemented and tested. The experimental results show that the developed control scheme can operate the DSPM motor properly, and the DSPM motor drive offers high efficiency over wide power range and good dynamic performance. Furthermore, the 2-phase operation mode of the 8/6-pole DSPM motor offers the potentiality of eliminating the torque ripple of the motor drive.
