摘要
基于转子与定子之间受力分析研究不同参量对电机转动性能的影响.分析定子加上高压电后其尖端附近的电荷和电场的变化;根据极间电场的分布,分析电荷在定子和转子之间的运动规律;当电荷漂移运动进行到一定时间后,定子和转子之间产生扭矩驱动转子的转动;再基于库仑定律对转子和定子之间的受力进行计算,并就电离子风对转子转动产生的影响进行理论分析.通过改变转子和定子之间的几何参数以及转子表面的导体材料,分别研究了其对转子转速的快慢和转动的稳定性的影响.
Based on the analysis of the force between the rotor and the stator,the effect of different parameters on the rotating performance of the motor was studied.First,the change of the charge and electric field near the tip of the stator under high voltage was analyzed.Then,according to the distribution of the electric field between the poles,the motion of the charge between the stator and the rotor was analyzed.After a certain time of charge drifting,a torque would be generated between the stator and the rotor to drive the rotation of the rotor.Then,the force between the rotor and the stator would be calculated based on the Coulomb law,and the effect of ionized wind on the rotation of the rotor would be analyzed theoretically.By changing the geometric parameters between the rotor and the stator and the conductive material on the surface of the rotor,the effects on the speed of the rotor and the stability of the rotation were studied,respectively.
