Boundary element method in reduction of cogging torque

IEEE Transactions on Magnetics, 1998
A method to optimize the cogging torque of a brushless motor with parallel magnetized magnets is presented. The technique is based on the boundary element method. The optimal width of the magnet and the optimal shifts of the consecutive magnets are computed.

EFFECT OF SKEWING ON THE COGGING TORQUE IN INDUCTION MACHINES

Electric Machines & Power Systems, 1994
ABSTRACT This paper presents a simplified method to predict the cogging torque in induction machines including the skewing effect An equivalent circuit including die effect of both slot harmonics and rotor skewing is developed. A special attention is paid to study the skewing effect on the machine behaviour especially at starting instant. Moreover, the

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.
