Transient analysis of permanent magnet linear synchronous motors
2005 European Conference on Power Electronics and Applications, 2005A modified one-dimensional mathematical model based on the space-vectors theory is used to analyse the performance of permanent magnet linear synchronous motors with starting and dumping sheet. The end-effects are taken into account by assuming that the length of the iron core is infinite and the length of the armature winding is finite.

Enhanced Modeling of Linear Permanent-Magnet Synchronous Motors
IEEE Transactions on Magnetics, 2007Modeling of air-gap flux density distribution produced by magnet poles is essential for analysis and design of linear permanent-magnet synchronous motors. This is usually done by time-consuming numerical methods which are difficult to be incorporated in iterative motor design procedures or by approximate models which lack desirable accuracy. This paper

Interior permanent magnet linear synchronous motor for high-performance drives
IEEE Transactions on Industry Applications, 1997Permanent magnet linear synchronous motors have been developed for factory automation, transportation applications, and so on. In the rotary-type permanent magnet synchronous machines, the wide speed and constant power operation are realized by using the reluctance torque due to the saliency and the flux-weakening control. In this paper, we examine the

Model predictive and compensated ADRC for permanent magnet synchronous linear motors
ISA Transactions, 2023Traditional linear active disturbance rejection control (LADRC) may have difficulty to achieve a rapid precise disturbance rejection for a permanent magnet synchronous linear motor (PMSLM). By making use of model information, a model predictive and compensated LADRC (MPLADRC) method is proposed in this paper.

A homopolar linear synchronous test motor using permanent magnets
IEEE Transactions on Magnetics, 1982The design, analysis, construction, and test of a small iron-cored linear synchronous motor (LSM) is described. The LSM uses a transverse flux homopolar configuration. Permanent magnets connect the base of the motor teeth and reduce the field coil requirements.
