Detent Force Analysis of Permanent Magnet Linear Synchronous Motor for Bearing Grinding Machine Application

摘要：

　　The detent force of permanent magnet linear synchronous motor (PMLSM) leads to the thrust ripple,vibration and noise in bearing grinding machines.In order to overcome the negative effect,detent force needs to be decreased.Through the analytical and finite element methods,two main components of detent force are investigated in this paper.Firstly,finite element analysis (FEA) and fast Fourier transform (FFT) are employed to analyze the end force.Then a three dimensional (3-D) FEA model of a short secondary PMLSM with skewed poles is erected and the cogging force is studied.Compared with the two dimensional (2-D) model of PMLSM without skewed poles,the detent force is remarkably reduced.
