Abstract

The present invention concerns a control device for an asynchronous motor, notably intended for the drive system of an electric vehicle. This control device comprises electric supply means able to produce an AC supply voltage whose frequency (FAL) and amplitude (UAL) may be adjusted independently of one another. For a given frequency of the supply voltage, the amplitude of this voltage is able to vary between a minimum value and a maximum value, the difference between the frequency of rotation of the turning magnetic field in the vicinity of the motor and the frequency of rotation of the rotor being maintained substantially constant as long as the amplitude of the supply voltage is less than said maximum value. Once this maximum value has been reached, the torque on the shaft of motor is increased by an increase of the slip.
