This paper introduces a Lorentz force type four-pole self-bearing motor, where the new pole arrangement of a stator is intended to function both as a synchronous PM motor and as a magnetic bearing. The Lorentz force type has some good points such as the linearity of control force, freedom from flux saturation, and high efficiency over conventional self-bearing motors. And also, compared with the previously proposed eight-pole type, this four-pole self-bearing motor is profitable for a high-speed rotation. Mathematical expressions of torque and radial force are derived to show that they can be separately controlled regardless of rotational speed and time. It is experimentally confirmed that the proposed scheme provides good feasibility of small high-speed self-bearing motor.
