Magnetic geared motors have many advantages over mechanical gearboxes, such as reduced maintenance and overload protection. However, the limited life of the mechanical bearings that hold the high-speed rotor is a problem in terms of durability. In order to solve this problem, the authors proposed a magnetic geared motor with additional three-phase windings to magnetically levitate the high-speed rotor. In this paper, a novel motor that applies the principle of a bearingless motor to a high-speed rotor is proposed for a consequent-pole type magnetic geared motor. Compared to the previously proposed magnetic geared motor with a magnetically suspended high-speed rotor, this method has the advantage of high torque density and improved controllability. In addition, the magnetic suspension and attraction forces in each topology were analyzed by finite element analysis.
