Thrust force of linear motor is one of the important factor to specify motor performance. In this study, we optimized maximizing the thrust force and minimizing the detent force of TFLM(Transverse Flux Linear Motor) using Response Surface Methodology by the table of orthogonal array. The Response Surface Methodology was well adapted to make the analytical model of the maximum thrust force and enable the objective function to be easily created and a great deal of the time in computation to be saved. Therefore, it is expected that the proposed optimization procedure using the Response Surface Methodology can be easily utilized to solve the optimization problem of electric machine.

The purpose of this study is to design 200 ㎾, 15,000 rpm 3 phase induction motor. This research deals with natural frequency and mode shape of rotating shaft of 3 phase induction motor with bearing stiffness by finite element analysis. We present natural frequency characteristic variation of rotating shaft according to change bearing stiffness. Also we are verified stability of rotating shaft from backward and forward critical speed by campbell diagram.
