ABSTRACT
PM AND RELUCTANCE SYNCHRONOUS MOTOR DRIVES
11.1. INTRODUCTION
PM and reluctance synchronous motors are associated with PWM voltage-source inverters in variable speed drives.
While PM-SM drives now enjoy worldwide markets, reluctance synchronous motor (RSM) drives still have a small share of the market in the low power region, though recently high saliency (and performance) RSMs with q axis PMs have been successfully introduced for wide constant power speed range applications (such as spindle drives).
