摘要: An electric asynchronous motor for driving a shaft, a roll shell or a similar machine element includes an annular rotor and an annular stator, each having an end face at each of their respective ends. The rotor is connected to a motor shaft by way of spokes. A motor cooling system includes an internal cooling air circuit wherein an air stream flows between the rotor and the motor shaft as well as through an annular heat exchanger for transferring heat from the rotor and/or the stator to a cooling liquid. The annular heat exchanger is positioned within the motor's housing in the area of an end face of the rotor. The cooling air stream also passes over blower vanes and at least one annular series of air circulation channels in the annular body of the stator and/or of the rotor with air streams flowing from the one end face to the other end face of the stator and/or of the rotor, so that the cooling air circuit forms an internal toroidal air stream.

摘要: In an electric motor drive, a asynchronous motor, such as drum motor, has a stator (2) mounted on a non-rotatory shaft (1) and has rotatory, like by means of bearings (3), connected rotor (4), is arranged to drive the machine construction (actuator). The rotor (4) of the asynchronous motor conveyor's is arranged to be directly a functional part of the machine construction (actuator), like conveyor's (5) driving roll (5a). Also the rotor can be formed as a shell of pulley (4) which is part of a vacuum belt conveyor comprising a stationary vacuum box (11), the rotor drive further including a non-rotatory shaft (1) supported by at least one supporting bracket (8) which is connected to the vacuum box.
