Permanent magnet rotor type electric motor

Image Number 10 for United States Patent #5990593.

A permanent magnet rotor type electric motor is formed of a stator core generating a rotation magnetic field, and a rotor core rotationally situated inside the stator core. The rotor core includes a first core member for generating a magnet torque, permanent magnets embedded in the first core member for forming magnetic poles, and a second core member for generating a reluctance torque without having a permanent magnet therein. The second core member is coaxially united with the first core member so that the rotor core is divided into the first core member for generating the magnet torque and the second core member for generating the reluctance torque.
