This paper describes a new form of radial flux type hysteresis motor having large output, high efficiency, and high power factor. The rotor has a copper‐sprayed surface layer on the rotor ring, which is made of Fe‐Cr‐Co magnet steel and has magnetic anisotropy and slits. The new configuration has two features. First, it is designed to give a combined hysteresis and reluctance‐motor action effectively, particularly at a synchronous speed. Second, it is designed to give a combined hysteresis torque and large torque due to eddy current in asynchronous conditions, particularly at starting. To analyze motor performance at synchronous and asynchronous operations, the finite‐element method is used. In this paper, magnetic hysteresis is considered by using complex permeability. The agreement between predicted and measured values of motor performance characteristics is good.
