Abstract
An electromechanical drive means comprising an a.c. motor (1) provided with a brake (2), a frequency converter provided with a control unit (9) and supplying the motor, and a gear (3) to change the rotational speed of the motor. To achieve efficient cooling, the drive means is provided with a cooling tunnel (5) housing the motor and the brake, the control unit (9) and the power stage semiconductor switches (8a-8f) of the frequency converter being located on the outer walls of this tunnel, the transmission gear (3) being located in the tunnel or close to it. <IMAGE>
