Cogging force compensation of a discontinuous permanent magnet track linear motor drive

2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017
Permanent magnet track linear motor drives are used in numerous industrial manufacturing processes covering a wide range of material handling and conveyor applications. A traditional solution is a permanent magnet linear motor (PMLM) in which the stationary part consists of permanent magnets and the moving part of the armature.

Cogging force rejection method of linear motor based on internal model principle

SPIE Proceedings, 2015
The cogging force disturbance of linear motor is one of the main factors affecting the positioning accuracy of ultraprecision moving platform. And this drawback could not be completely overcome by improving the design of motor body, such as location modification of permanent magnet array, or optimization design of the shape of teeth-slot. So the active

Cogging Force Optimization of Double-Sided Tubular Linear Machine With Tooth-Cutting

IEEE transactions on industrial electronics (1982. Print), 2021
The double-sided tubular linear machine (DSTLM) has a more compact structure than general single-sided motors, resulting in a higher power density, typically at the cost of a higher cogging force.

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.

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.
