Permanent magnet synchronous motor discrete linear quadratic speed controller
2011 IEEE International Symposium on Industrial Electronics, 2011This paper describes a discrete linear quadratic speed regulator (LQR) for permanent magnet synchronous motor design. Linearization and decoupling processes of a motor model were discussed. An internal input model was introduced to control algorithm in order to eliminate the steady state speed error caused by step reference speed as well as load torque

Improvement of Cogging Thrust in Permanent‐Magnet‐Type Linear Synchronous Motors
Electrical Engineering in Japan, 2013SUMMARYThis paper presents a method for reducing cogging thrust in permanent‐magnet‐type linear synchronous motors. A phase shift method and supplement tooth method are proposed. The methods do not affect the original thrust performance of the linear motor, nor do they greatly modify its basic shape.

Magnetic circuit analysis of a linear synchronous motor with permanent magnets
1992. Digests of Intermag. International Magnetics Conference, 1992The authors describe a magnetic circuit analysis of a permanent-magnet-type synchronous motor using the finite element method. The effect of the size of the permanent magnets on the static thrust characteristics is investigated, and a prototype machine is fabricated on the basis of the results.
