Abstract For 12-slot/11-pole double-sided permanent magnet linear motor, this paper proposes an effective method by shifting the armature or magnetic pole a certain distance to weaken the thrust ripple, and carries out the structure optimization. Based on this optimal design, the electromagnetic and thrust force performances are studied at the no-load and rated load, and validated by prototype measurement. Comparing with other two structures which have more poles number than slots number (12-slot/13-pole, 12-slot/14-pole), the results not only verify the applicability of this shifting method, but also indicate that the thrust force performance will be improved if the poles number is larger than the slots number. Therefore, 12-slot/14-pole structure has better thrust force performance.

Key words： Double-sided permanent magnet linear synchronous motor shifted type slot/pole combination optimal design
