A Reluctance Magnetic Gear for High Speed and Vibration Motor Systems

Abstract

This paper proposes a reluctance magnetic gear for high speed and vibration rotational situations. This novel magnetic gear adopts a structure with two non-magnetic rotors and one magnetic stator based on the reluctance modulation effect. The rotors are made of silicon iron, which makes the magnetic gear stable and reliable at high rotational speed in motor systems. By applying a 2D FEM simulation, the magnetic flux distributions of the air gap and torque transmission are analyzed. The results show that the proposed reluctance magnetic gear can offer a smoother torque transmission in high speed and vibration condition than the existing reluctance magnetic gear.
