N2 - Magnetic gears achieve the system with maintenance-free, low noise and low vibration characteristics by contact-less power transformation. However, conventional magnetic gears are not suitable system for high speed motors because the mechanical strength is weak due to permanent magnets of the high speed rotor. This paper presents a novel flux switching magnetic gear for the super high speed motor. The high speed rotor of the proposed magnetic gear is constructed by only iron core. Therefore, the structure is very simple and robust and it is possible to rotate in the high speed region. Moreover, the flux switching magnetic gear realizes the high torque density by utilizing the magnetomotive force of stationary field magnets. In this paper, the performances of the proposed magnetic gear including torque density, mechanical strength, loss and efficiency are evaluated.
