摘要
针对12槽/11极双边型永磁直线电机,提出了采用电枢或磁极错位一定距离来削弱推力波动的有效方法,并进行了结构优化设计。针对该优化方案,研究了空载工况和额定工况时的电磁性能和推力性能,并进行实验测量与验证。通过与另外两种极数比槽数多的槽极配合(12槽/13极、12槽/14极)结构相比,不仅验证了错位方法的通用性,而且表明了极数比槽数多的槽极配合结构力性能更好,即12槽/14极结构力性能更优。
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.
