碩士 === 國立雲林科技大學 === 電機工程系碩士班 === 99 === A new permanent magnet excited transverse flux synchronous linear motor is studied in this thesis. The translator of this new linear motor consists of cross-shaped core set. The value of the translator’s thrust under an ideal condition is first derived using electromagnetic theory, and the magnetic flux leakage coefficient is calculated. Then, a graphical software package is used to create 2D model of the permanent magnet synchronous linear motor. By varying the parameters of air gap length, magnet dimensions, pole pitch and tooth width of the translator, the thrust of the linear motor will be analyzed and optimized. COMSOL Multiphysics is used to simulate the 2D model of the permanent magnet synchronous linear motor. The parameters which allow the most powerful thrust to be produced are chosen for designing the motor.
