摘要
我国对外开放,发展经济,引进国外的先进技术和设备,这样就产生了一些60 Hz和不同电压的设备电动机。通过对电动机的空载电流、转矩、效率、功率因数、温度等的分析,阐明了在我国50 Hz、380 V标准电源上应用时,应注意的问题。
With reform and opening-up and the development of economy, we have brought in a series of advanced technologies and equipment, thus introducing some motors which are of 60 Hz and different voltages. This article is based on the no-load motor current, torque, efficiency, power factor, temperature and other analysis, elucidating the problem on the application of our standard 50 Hz 380 Volt power.
