【Abstract】 In this paper, we pointed out the problem of low efficiency of high-voltage electric motor in China. The adjusting speed on high-voltage electric motor by the frequency- conversion is introduced. The direct "high voltage -high voltage" conversion of the adjusting speed on high-voltage electric motor system by frequency- conversion is the most advanced and high-efficiency way. In the end, its high-efficiency is calculated and analysed by examples.更多还原
