转动惯量对同步电机起动及运行的影响分析

Influence Analysis of Inertia Moment on Start and Operationof Synchronous Motors

研究了转动惯量对同步电机起动及运行的影响。从转动惯量对电机起动时间、定子电流波动、阻尼绕组温升三个方面进行分析。分析结果表明:负载转动惯量越大,电机起动时间越长,电机定子电流波动越小,电机定子电流波动越小。

This paper researches the influence of inertia moment on the starting ability and operation of synchoronous motor,which is carried out based on three aspects of analyses such as the starting time,stator current fluctuation and damping wingings temperature rise.The analytical results show that the larger the inertia moment of load,the longer the starting time of motor,the smaller the stator current fluctuation of motor.
