Suppression of Cogging Torque for Line-start Permanent Magnet Synchronous Motor
The stator and rotor of line-start permanent magnet synchronous motor ( LSPMSM) are slotted on both sides, which greatly increases the difficulty of analyzing the characteristics of cogging torque of LSPMSM and studying its suppression methods. The existing methods to suppress the cogging torque of...

| description | The stator and rotor of line-start permanent magnet synchronous motor ( LSPMSM) are slotted on both sides, which greatly increases the difficulty of analyzing the characteristics of cogging torque of LSPMSM and studying its suppression methods. The existing methods to suppress the cogging torque of LSPMSM have limited effect. Firstly, based on the analytical model of the air-gap magnetic density distribution when the permanent magnet acts alone and the air-gap magnetic permeability function distribution caused by the stator and rotor slots, the analytical model of the cogging torque of LSPMSM is established. Then, the method of determining the motor structure parameters that can effectively suppress the cogging torque is studied. Finally, taking an 18. 5 kW LSPMSM as a prototype , the stator tooth width and rotor tooth width that can effectively suppress the cogging torque are determined. The results show that, compared with the existing methods, the stator tooth width and rotor tooth width of the motor determined in this paper can further reduce the cogging torque of the motor by 46. 64% and 65. 98% , and it will not have a significant impact on the operating performance of the motor. |
