<p>An electronic control circuit for induction electric motors driving electric vehicles which by varying the feed voltage and frequency of an inverter-fed three-phase short-circuited rotor induction motor on the basis of the vehicle speed and the accelerator position, enables the speed and acceleration of an electric vehicle to be regulated at the request of a user, independently of resistant torque variations, while maintaining the slip value equal to a desired slip value during any stage of operation, including that in which the motor operates as a generator. <IMAGE></p> |
