摘要:

针对串激电机原材料成本不断上涨的情况,文中基于一款电镐电机,提出了一种新型四极单相串激电机设计。该电机电枢绕组端部较短,电刷数较少,且定子辅助磁极无需励磁绕组,可有效减少串激电机的材料成本。通过对传统两极串激电机结构的改进,初步确定了新型四极串激电机的结构参数。利用Maxwell软件建立了电机二维有限元模型,对新型串激电机的数学模型和气隙磁密进行分析,并对电机的运行特性和带负载性能进行对比分析。结果表明,四极串激电机在运行特性、带负载性能等方面优于原两极电机。以上发现也为电机进一步优化提供了研究基础。

Abstract:

In order to reduce the cost of the universal motor, a new four pole double brush universal motor is designed based on a pick motor. The motor has the advantages of short end of armature winding, reduced brush number, and no need of excitation winding for stator auxiliary magnetic pole, which can effectively reduce the material cost of the series motor. By improving the structure of the traditional two-poles series motor, the structural parameters of the new four-poles series motor are preliminarily determined, and the two-dimensional finite element model of the motor is established using Maxwell software. The mathematical model and air gap flux density of the new series motor are analyzed, and the operating characteristics and load performance of the motor are compared and analyzed. The results show that the four-poles series motor is superior to the original two-pole motor in terms of operating characteristics and load performance. The above findings provide a research basis for further optimization of the motor.

Key words: four-poles universal motor, wave winding, mathematical modal, operational characteristic, gap flux density, finite element analysis, load performance, Maxwell
