Active cogging torque construction by the weld slot design in a positioning servo system

IET Electric Power Applications
The 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 Technology
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.

Analysis and Design of a Permanent-Magnet Outer-Rotor Synchronous Generator for a Direct-Drive Vertical-Axis Wind Turbine

Iranian Journal of Electrical and Electronic Engineering, 2014
In Permanent-Magnet Synchronous Generators (PMSGs) the reduction of cogging torque is one of the most important problems in their performance and evaluation. In this paper, at first, a direct-drive vertical-axis wind turbine is chosen.
