双交替极横向磁通直线电机的基础研究
|
摘要
提出一种新型双交替极横向磁通直线电机。该结构集成了两种交替极横向磁通电机拓扑,位于初级和次级的永磁体产生的磁通以相同的方向与绕组相交链,通过共用部分铁心和绕组,充分利用了电机内部空间,提高了材料利用率,增大了电机推力密度。通过分析电机内磁场分布,建立电机磁网络拓扑,并计算绕组磁链,推导电机电磁力表达式。通过有限元对理论分析进行验证,得到电机磁链、反电势及电磁推力分布波形。研制一台实验样机,测量样机的反电势,验证新结构电机的原理与性能。
A novel dual consequent-pole transverse-flux linear motor has been proposed in this paper. This motor incorporated two individual consequent-pole transverse-flux motor topologies, which have common flux path interlinking the winding. The proposed structure can achieve high utilization of material and improve the thrust density by fully taking advantage of the inner space of the motor. The reluctance network was established after analyzing the magnetic field distribution, and the flux-linkage was calculated along with the thrust expression. 3-D finite element analysis(FEA) method was employed to find the waveform of flux-linkage, back electromotive force(EMF) and thrust force to validate the theory. Furthermore, a prototype motor was manufactured and measured.
