Abstract

A PWM induction motor drive is compared to a switched reluctance motor drive based on the same motor size and on the same specifications. Both low cost variable speed drives were developed for 400 W output power and a large speed range (up to 15000/min). The main differences of the motors and the power converters are discussed and the drive performance is presented by means of measurements. It is shown that the switched reluctance motor drive is advantageous for low cost applications if audible noise can be accepted and efficiency and dynamic performance are important in the lower speed range: 0 . . . 5000/min. If a larger speed range is required or silent motor operation is desired, the PWM induction motor drive has to be preferred
