Direct current electric motor controlling method for motor vehicle, involves comparing induction voltage induced in cable by rotor with preset voltage value, and starting supplying of current to cable so that voltage reaches preset value

摘要

The method involves supplying current to a winding cable (20) of an internal stator of an electric motor for a constant time period, when the motor is operated with a constant rotational speed. An induction voltage induced in the cable by an external rotor is determined after terminating the supply of current to the cable, and the induction voltage is compared with a preset induction voltage value. The supplying of the current to the cable is started so that the induction voltage reaches the preset voltage value, and the time period is adjusted depending on the supply voltage.
