In this paper, the influence of slot/pole number combination on the performance of consequent pole permanent magnet linear synchronous motors (CP-PMLSMs) is analyzed. First, by adopting simplified magnetic circuit method, the working principle and characteristics of CP-PMLSM are introduced. Then, finite element models of 16 selected CP-PMLSMs with different slot/pole number combinations are established, electromagnetic properties of these motors are fully investigated and compared. Finally, the slot/pole number combination selection criteria of CP-PMLSM are obtained according to the preceding analysis results.
