Analysis of Mechanical Characteristics of Three-phase Motor with Rotor Serial Capacitance

在对三相电动机的转子进行串电容处理后,从转子串电阻、减少电源电压以及降低电源频率等角度,全面分析电容转子三相电动机机械特性,得到相对理想的电动机起动机械特性,为工业生产时的电动机参数选择提供借鉴,进而发挥电动机在实际生产作业中的积极作用。

After treating the rotwor of three-phase motor with series capacitance, the mechanical characteristics of three-phase motor with capacitance rotor are analyzed comprehensively from the angles of rotor series resistance,reduction of power supply voltage and reduction of power supply frequency. The relatively ideal characteristics of motor starting mechanism are obtained, which can provide reference for the selection of motor parameters in industrial production, and then give play to the positive role of motor in practical production.
