description This paper compares the application of two different sinusoidal magnetization methods of a bonded magnetic ring in a permanent magnet motor. Sinusoidal magnetization of a bonded magnetic ring can be realized by eccentric pole cutting or magnetization with eccentric fixture. Firstly, the parametric optimization of the two methods is carried out by finite−element simulation software, with the goal of minimizing the total harmonic distortion (THD) of Air−gap flux density. Then, when the THD of Air−gap flux density is roughly the same, the cogging torque, output torque, back−EMF, magnet dosage, and other parameters of the two magnets in the application of permanent magnet motor are compared. The results show that the performance of the two methods is similar, and the two methods have their own advantages. Finally, an eccentric bonded magnetic ring and eccentric magnetizing fixture are made, respectively, for experimental comparison. The experimental results are consistent with the simulation results. This paper can provide some reference value for the selection of sinusoidal magnetization mode of a bonded magnetic ring.
