Abstract :
To improve the performance of permanent magnet (PM) machines, quasi-Halbach PM arrays are used to increase the magnetic loading in these machines. In tubular PM actuators, these arrays are often approximated using segmented magnets resulting in a 3D magnetic field effect. This paper describes the results of this segmentation obtained from an analytical model.
