提出了一种采用绕线式超薄钢带铁心的三相8极高速双轴向间隙感应电机。该Dagim有一个双定子和一个单转子。根据流经线圈的电流方向，双定子有两种拓扑：NN和NS。因此，本文研究了这些拓扑结构、转子轴向宽度和转矩之间的关系。其次，为了在不改变定子结构的情况下对该电机进行改进，采用三维有限元分析方法研究了转子三维结构变化对电机性能的影响。分析了转子转角和转子杆数对扭矩的影响。
A 3-phase, 8-pole high-speed dual axial gap induction motor (DAGIM) using a wound ultra-thin steel strip core has been proposed. This DAGIM has a double stator and a single rotor. The double stator has two topologies, NN and NS, depending on the direction of the current flowing through the coil. In this paper, therefore, the relationship among these topologies, the rotor axial width, and the torque is investigated. Secondly, the characteristics of the DAGIM when the three-dimensional (3D) structure of the rotor is changed are investigated by 3D finite element analysis in order to improve this motor without changing the stator structure. As a result, the effect of skew angle and number of rotor bars on torque is clarified.
