摘要：

The combination principles of pole-pair numbers of inner rotor, outer rotor and modulation teeth for the coaxial magnetic gear are studied. The topology of coaxial magnetic gear is introduced and the air-gap flux densities are investigated theoretically. The possible combinations of the pole-pair numbers of inner rotor, outer rotor and modulation tooth are studied based on the analysis of air-gap flux density harmonics. Four magnetic gears with different combinations of pole-pair number are designed and comprehensively compared based on finite element algorithm.A magnetic gear with 5 inner-rotor pole pairs, 19 outer-rotor pole pairs and 24 modulated teeth was manufactured and tested.Both the theoretical analysis and test results demonstrate that the magnet gear could enjoy strong torque transmission capability and high gear ratio when the number of modulated teeth is the sum of pole pair numbers of inner and outer rotors. © 2021, Editorial Board of Acta Armamentarii.
