“…Shen et al [5] and Li et al [6] found that different shapes of incomplete grooves were in the rotor, with the most significant reduction in the cogging torsion and less distortion of the air gap magnetism tight when incomplete curved grooves were in the rotor. In addition, the position of the incomplete groove is also important.…”

To address the problem of vibration and noise caused by high slot torque of stacked-in permanent magnet synchronous motor, a motor model with a rectangular slot in the stator and curved slot in the rotor is proposed to analyze the variation of slot torque with the auxiliary slot parameter based on the analysis of slot torque, taking an 8-pole 36-slot built-in permanent magnet synchronous motor as an example. The modeling results display that the slot torque reduces and then increases with the change of incomplete groove parameters. The slot torque is weakened by 92.01% when the stator with a rectangular slot rotor with a curved slot.

“…The literature 4 set up alternating magnetic barriers between adjacent permanent magnets in a V-rotor permanent magnet motor and analyzed the effect of its parameter changes on magnetic leakage. In terms of optimizing the air gap magnetic density, rotor pole optimization 5 , setting magnetic barriers 6 , and opening auxiliary slots [7][8] are commonly used. The literature 9 designed a stepped permanent magnet structure motor and investigated the influence of permanent magnet parameter settings on the air gap magnetic density waveform.…”

To further improve the torque performance of permanent magnet torque motors and enhance the magnetic stability of surface-mounted permanent magnets, a new dovetail magnetic isolation device (DMID) is discussed. First, the initial model of the motor is constructed and the structure of the DMID is parametrically designed. Second, a mathematical model of the average torque and torque ripple considering the DMID is developed based on the equivalent magnetic circuit model of the motor and the principle of electromagnetic torque generation. Then, with the help of the ANSYS Maxwell finite element simulation tool, the average torque is used as the optimization target, and the variation pattern of the slot width, inner circle radius, and position of the DMID are simulated and discussed. Finally, the average torque and torque ripple of the optimized motor are compared with those of the initial motor, and the results show that the average torque is increased by 37.2 Nꞏm and the torque ripple is weakened by 0.04% when the optimal parameters of the DMID are selected.
