Abstract
- Cogging forces result in thrust ripples and noise, which result in poor positioning accuracy. For that reason, cogging force reduction is one of the most important factors to be considered in the design of permanent magnet linear synchronous motors (PMLSMs) with core type topologies. Many methods have been reported regarding the reduction of the cogging force in PMLSMs. However, since they usually could cause a large decrease of thrust, it is important to select an appropriate method for cogging force reduction by considering a tradeoff relationship between large thrust and small cogging force. This paper presents the design for cogging force reduction of a double-sided transverse flux permanent magnet linear synchronous motor. Several methods including chamfering, skewing, and magnet pole shifting are applied for cogging force reduction. Finally, the design results are analyzed and experimentally validated by the prototype model. [ABSTRACT FROM AUTHOR]
