Abstract

PURPOSE:To raise the efficiency of motor and reduce the cost of operation as well as avoid the occurrence of the disorder of rotation by using a hysteresis motor in a rotor-rotating drive portion. CONSTITUTION:The motor rotor 5 is made of a hysteresis material, and a rotation drive mechanism made up of a hysteresis motor to flow AC current is provided in the motor stator. When the motor rotor 5 turns at a synchronous speed, an excitation force generated in the motor stator 9 is at rest against the rotor because of rotation at a synchronous speed and a magnetic flux is generated by the excitation force inside the motor rotor 5. Thus, the hysteresis motor is turned by a rotating force generated between the excitation force and the magnetic flux.
