This paper describes the development of a motor that can be mounted on a compact, energy-efficient, one-degree-of-freedom controlled magnetic bearing. First, the motor is designed. The motor consists of 12 coils attached the stator and a Halbach permanent magnet array attached the rotor. When a three-phase pulse current is applied to the coils, the repulsive or attractive forces with each permanent magnet in the rotor can be generated, and the rotor can be rotated. Next, the dimensions of the coil and, permanent magnet are optimized using magnetic field analysis. Then, the motor is prototyped and, the performance is evaluated.
