Linear Motors

Objective: Ironless, permanent magnet, synchronous linear (IPMSL) motors are applied widely in precision servo control for the nonexistence of cogging forces and comparatively small fluctuations in thrust and speed. Method: The air and water cooling structures are designed by assuming the heat loss in the motor operations is the source for the distribution of the temperature field in the analysis under natural cooling. Conclusion: The temperature fields of the linear motor under the two cooling modes are compared and analyzed, which helps monitor the temperature of linear motors during development and operations.

Permanent Magnet Materials

With the progress of linear motors and permanent magnet materials, three kinds of magnetization methods have developed for permanent magnet linear motor. Based on the analysis of magnetic field distribution of radial, Halbach and tangential magnetization, the impacts are investigated of these methods on performances of permanent magnet linear synchronous generator (PMLSG) through simulation. Advantages and disadvantages of these methods are unveiled by studying and comparing their flux linkage, magnetic detent force and EMF harmonics. A conclusion can be drawn that radial magnetization suits PLMLSG better.
