摘要：
In order to improve power efficiency, Halbach magnetized topology is applied to a short secondary slotted permanent-magnet linear synchronous motor (PMLSM). Detent force of slotted PMLSMs is due to the interaction between the edges of the permanent magnet and the teeth of the primary core. This paper deals with detent force reduction methods such as adjustment of magnet length and skewing. Reduction effect of detent force and thrust performance for two topologies are also compared.
