Abstract
Abstract Speed varying system for an asynchronous motor having a double rotor R. The variation in the speed of this motor is obtained by powering one of the stators (2) by groups of semiconductor contactors (5, 6), firstly in phase by a first group then in phase opposition by another group, the conduction period for each group of contactors being determined by a control circuit (8, 9, 10).
