Dynamic Analysis of a Magnetic Gear Using its Torque Map

Abstract

　This paper proposes a dynamic simulation method of a magnetic gear using its torque map. The phase angle difference between the input and output rotors depends on a load of the output rotor. The load contains an external load and brake torque due to internal mechanical and iron losses. In this situation, the dynamic performance of a magnetic gear is computed by a transient analysis using a motion equation, and the computation cost is large. In order to reduce the com-putation cost of a magnetic gear, a dynamic simulation method using its torque map is proposed and discussed.
