Abstract
Field modulation magnetic gear is a transmission device with broad development prospects. It has the advantages of no friction, no pollution, low maintenance, and easy installation. Magnetic gear models with different gear ratios are established. The input and output torque waveforms of different models are compared. The influences of the number of pole pairs of the inner rotor (P1) and the number of pole pairs of the outer rotor (P2) on torque ripple are analyzed. According to the principle of magnetic field modulation, the torque ripple of magnetic gear is greatly affected by P1 and P2. Research results show that the torque ripple can be effectively reduced by selecting the magnetic gear with P1 = 4, P1/P2 = 1/(n+0.25) or 1/(n+0.75) (n is a natural number).
