Abstract

PURPOSE: To eliminate mis-commutation in a winding-type induction motor of a scherbius type speed control system due to excess voltage resulted such as by instantaneous interruption of a power source, by the provision of a reactor between the secondary side of the motor and a thyristor switch.
