Abstract There is the large normal force ripple between the mover and stator when the single-side flat-plate permanent magnet linear servo motor (PMLM) is operating, and the friction force perturbation and the vibration of the machine tool caused by the normal force ripple will influence the accuracy of machine tool greatly. The cogging effect of PMLM is one of the important factors that cause the normal force ripple. Therefore, the normal force analytic expression of the infinitely long side tooth PMLSM which is derived with the Maxwell tensor method, which reveals the law of the normal force fluctuation caused by cogging effect. The primary harmonic of normal force caused by cogging effect is obtained by Fourier decomposition method, and the three sections of magnets staggered method to weaken the normal force ripple is presented to remove the lateral movement of the motor in traditional skewed pole and phase shift optimization methods. In the end, take 12 slots 8 poles PMLSM with obvious cogging normal force ripple for example, the finite element simulation and experiment methods are employed in this paper, and the results show that the method can reduce the cogging effect effectively without changing the thrust of PMLSM.

Key words： Permanent magnet linear servo motor cogging effect normal force ripple three sections of magnets staggered method
