Abstract

Sensorless vector control for induction motor drives is widely used. However, in the case of mass-produced closed-slot motors, it is difficult operate them at zero frequency with regenerative load. In this paper, a sensorless vector control method based on three-phase PWM carrier waves is applied to a mass-produced closed-slot induction motor. Further, methods to improve stability are proposed.
