Abstract

PURPOSE:To control the generation of pulsation torque and prevent a superheated condition by providing a rotor iron core with a part having the secondary conductor and another part having no secondary conductor viewed in the axial direction and by making the part having no secondary conductor also to face against the stator iron core. CONSTITUTION:The rotary driving gear is composed of an AC power source 1, an inverter 2 as the frequency changing means consisting of a forward transducer and a power inverter, and an induction motor 3, which is increased in power with the output of the inverter 2. The stator core of the induction motor 3 has the parts 4a and 4b having the cage coil windings 5a and 5b as the secondary conductors and the part 4c having no cage coil windings. These 4a, 4b and 4c are arranged in the axial direction and the stator iron core 6 is faced against 4a and 4b having the cage coil windings of the rotor iron core 4 but also faced against 4c. When the output of the inverter 2 increases power of the motor 3, leakage magnetic flux is generated between the iron core 4c and the stator iron core 6 to increase reactance of the primary coil winding. Thereby the high frequency current which changes in proportion to the frequency can be controlled.
