摘要
为了拓宽感应电机的调速范围,提出一种大小极环形绕组实心转子感应电机(LSPTWSRIM)。介绍了LSP-TWSRIM的结构,研究了其工作机理,并给出了其设计参数。建立了二维有限元模型,并分析了不同工况下LSP-TWSRIM的电磁特性(包括定子电流、气隙磁通密度、转速和转矩)。设计并制造了一台LSP-TWSRIM样机,并进行了实验,通过对比仿真和实验结果证明了LSP-TWSRIM的工作机理和电磁特性的正确性。
In order to widen the speed range of the induction motor, a large-small pole solid-rotor induction motor with toroidal winding(LSP-TWSRIM) is proposed herein. The structure of LSPTWSRIM is introduced, its operating principle is studied, and its design parameters are given. A twodimensional finite element model was established and the electromagnetic characteristics of LSPTWSRIM(including stator current, air gap flux density, speed and torque) under different working conditions were analyzed. An LSP-TWSRIM prototype was designed and manufactured, and experiments were carried out. The comparison between simulation and experimental results proved the correct operating principle and electromagnetic characteristics of LSP-TWSRIM.
