Reduction of Cogging Force in Linear Permanent-Magnet Generators

IEEE Transactions on Magnetics, 2010
Although linear permanent-magnet generators (LPMGs) are widely used for converting wave energy into electrical energy, they suffer from large cogging force. The cogging force causes oscillatory output power, which shortens lifetime and increases the maintenance costs of the generators.

Determination of tooth cogging force in a hard-disk brushless DC motor

IEEE Transactions on Magnetics, 2005
The paper proposes a new method to determine the tooth cogging force in a brushless DC (BLDC) motor which is used in a hard-disk application. This force might be a source of tooth vibrations and motor noise. In the new method, the permanent-magnet (PM) poles are substituted with their equivalent currents.

Reduction of cogging forces in linear synchronous motors

1999 IEEE Africon. 5th Africon Conference in Africa (Cat. No.99CH36342), 2003
Cogging forces in linear synchronous motors are due to the interaction between the edges of the permanent magnet and the teeth of the primary core. Various techniques can be employed to reduce the cogging force, namely, the optimisation of the magnet length, the use of semi-closed slots, the variation of the air-gap length and skewing.

Magnetic gear: Radial force, cogging torque, skewing and optimization

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
Magnetic gears are able to transmit torque between an input and an output shaft without mechanical contact. As for electrical drives, torque density, acoustic noise, and torque ripple are of primary concern. This paper describes the influence of the pole numbers on the radial forces and the cogging torques.
