Study of Cogging Torque in Permanent Magnet Machines

Electric Machines & Power Systems, 1999
Cogging torque is produced in a permanent magnet machine by the magnetic attraction between the rotor-mounted permanent magnets and the stator. It is an undesired effect that contributes to the machines' output ripple, vibration, and noise. This paper analyzes various cogging torque minimization techniques as applied to a permanent magnet machine used ...

Influence of Closed Stator Slots on Cogging Torque

2013
Cogging torque results due interaction of magnetic field of magnets and stator slots, and have negative effects on permanent magnet machines such as vibrations, noise, torque ripples and problems during turbine start-up and cut-in. In order to reduce cogging torque this paper presents a study of influence of closed stator slots on cogging torque using ...

Calculation of Cogging Torque in Hybrid Stepping Motors

2013
When the windings of a hybrid stepping motor are unexcited the permanent magnet’s flux produces cogging torque.  This torque has both desirable and undesirable features depending on the application that the motor is put into. This paper formulates an analytical method for predicting cogging torque using measured flux-linkage data.
