摘要
电动机过载时,需电动机的发热情况是否能满足绝缘等级的要求。参考标准IEC 60034-1《2004-04旋转电机定额及性能》进行了在变频器供电下电动机的温升试验。试验结果表明,对于变频器供电的电动机在调速传动运行时,其温升需考虑冷却方式、负载工作制以及变频电源。
When motor overload, in order to analyze the motor heating situations whether could meet the requirements of the insulation class, conducted the motor temperature rise test which was under inverter power supply. The test results showed that when the inverter power supply motor is running in speed regulation of drive, the temperature rise should taken cooling mode, work load and Frequency power supply into consideration.
