Abstract

Control device for an electric motor with stator winding, in particular an asynchronous motor. A DC voltage (12) is chopped by means of variable frequency and variable mark/space ratio switches (151, 181) in such a way that in each chopping period the intensity of the stator current is dependent on the mark/space ratio. A generator (20) is provided so that this mark/space ratio varies sinusoidally. The chopping frequency is variable in order to permit frequency variation of the sinusoid and hence speed variation of the motor. <IMAGE>
