WOUND ROTOR AND WOUND ROTOR ASSEMBLY THAT CAN GENERATE SUPERIMPOSED MAGNETIC FIELD IN THE SAME DIRECTION

原文（中国語）

A wound rotor assembly is capable of generating a superimposed magnetic field in the same direction, and includes a shaft and a wound rotor that generates the superimposed magnetic field. The wound rotor includes a rotor core, multiple magnets, and several coil windings. The rotor core includes a yoke portion, several tooth portions, and several shoe portions. The yoke portion is fitted onto the shaft. The tooth portions are extended outwardly and radially from the yoke. The shoe portions are formed at the opposite ends of the tooth portions relative to the yoke portion. The magnets are fixed to the shoe portions to generate a basic magnetic field when the rotor core rotates. The coil windings are fitted onto the tooth portions to receive control power and generate the superimposed magnetic field in the same direction as the basic magnetic field when an intensity of the basic magnetic field does not reach to the required magnetic field intensity.
