Abstract

Synchronization capability of line start permanent magnet synchronous (LSPMS) motors is a key factor in design and optimization of these motors. This paper presents a simple analytical method for finding critical slip in synchronization assessment of LSPMS motors. Appropriate approximations are employed in the method resulting in significant simplification of the method with reasonable accuracy. The proposed method is time efficient and can be easily included in iterative design procedures. Accuracy of the proposed method is evaluated by dynamic analysis of two different motors. Also, the experimental results are presented to support the analytical and simulation results.
