感应电动机的运行状况分析

Analysis on Operating Conditions of Induction Motor

在电动机实际运行中常常遇到电压与频率与额定值发生偏差的情况,当电压与频率与额定值发生偏差时,电动机自供电网络吸收的定子电流、有功功率、无功功率、转子电流、损耗、转速以及电动机发热等均将产生变化,本文将就上述变化做出较为详细的分析。

The deviation between vohage or frequency of motor and its rated value usuallyexists in the actual operation. At this condition, the stator current, active power, reactive power, rotor current, loss, rotating speed and heating of motor absorbed by its self-powered network will change. This paper analyzes the above changes in detail.
