In an electric motor, such as a DC brushless motor or the like, having a permanent magnet in a rotor, each magnetic pole is formed of three permanent magnets, and the permanent magnets are made of at least two kinds of magnetic materials represented by ferrite magnet and rare-earth magnet, thereby providing a permanent magnet rotor type electric motor in which a reluctance torque and a magnetic flux density can be selectively established, and cost is reasonable, corresponding to the quality.
