PURPOSE : A permanent magnet type motor is provided to improve performance of a motor without increasing a cost by constructing the motor with mixing an expensive rare earth magnet and an inexpensive ferrite magnet.
CONSTITUTION : A permanent magnet type motor includes a stator(50) and a rotor(60). A coil(55) is wound on the stator(50). The rotor(60) includes a magnet(65). And, the magnet(65) is placed at a position corresponding to the stator(50) and is made of material having different remaining magnetic flux density or different energy.
