Abstract
For permanent magnet linear synchronous motor (PMLSM), the end effect not only changes the distribution of the end magnetic field, but also causes the pulsating magnetic field in the air gap between the primary and the secondary components. In this paper, the existence of the pulsating magnetic field is proved and the characteristics of the pulsating magnetic field are analyzed through the finite element analysis. On the base of that, the influence of the pulsating magnetic field on the detent force is studied, of which the result shows that the pulsating magnetic field generates the pulsating magnetic force, which is a part of the detent force. The amplitude of the pulsating magnetic force is closely related to the length of the primary component. By adjusting the length of the primary component, the pulsating magnetic field can be effectively suppressed. Moreover, the results of simulation and theoretical analysis prove that with the increase of primary component length, the influence of pulsating magnetic field is becoming weaker and weaker. Finally, a prototype is made to test the detent force characteristics, which verifies the research theory in this article.
