In this paper, a magnetic-geared motor with an integrated bearingless high-speed rotor is proposed. Active two-axis suspension forces are provided to the suspended high-speed rotor by three-phase suspension windings. The principles of magnetic suspension and torque generation are presented. In addition, the suspension characteristics are evaluated in 3-D finite element analysis. A test machine was built, and both magnetic suspension and rotation were verified. As a result, the principle of a magnetic-geared motor with a magnetically suspended bearingless high-speed rotor has been confirmed for the first time.
