ABSTRACT:
The disclosure is of a variable speed three-phase motor with a intermediate rotor and inner rotor, where the pack of laminations of the main rotor is prolonged as an annular pack of laminations in the direction of the longitudinal axis with short-circuit rods extending over the whole length of the stator, thereby forming an annular intermediate rotor inside which the inner rotor with its short-circuit rods rotates.
