Active cogging torque construction by the weld slot design in a positioning servo system
IET Electric Power ApplicationsThe cogging torque is usually considered as an adverse effect of the PM machine servo system. This paper presents a new perspective that the cogging torque can be exploited in many practical situations as long as the speed ripple can be suppressed.

Suppression of Cogging Torque for Line-start Permanent Magnet Synchronous Motor
Journal of Harbin University of Science and TechnologyThe 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.
