Objective
2
Aiming at the problems of unbalanced magnetic pull (UMP) and low structural strength of high-speed rotor in the operation of permanent magnet assisted magnetic gear
relevant research was conducted.
Methods
2
Firstly
the phase tuning method was used to study the influence of different transmission ratios on the UMP. Then
according to the structural characteristics for the high-speed permanent magnet rotor of the magnetic gear
the analytical solution of the rotor strength was obtained by using the equivalent mass ring method. Finally
taking reducing the maximum stress and ensuring a certain output torque as the optimization objectives
the multi-objective optimization was performed on the relevant parameters of the magnetic isolation bridge and magnetic barrier.
Results
2
The analysis results indicate that a transmission ratio where the maximum common divisor of the number of magnetic blocks and the number of poles of the low-speed rotor

validating the accuracy of the analytical method. Through the optimized design
the maximum stress on the rotor is significantly reduced.
