我測量了6臺設(shè)備的電動機(jī)空載電流
電動機(jī)功率           空載電流              
1.6KW                1.7A        
3.7KW                                3.3A
3.7KW                                3.0A
3.7KW                                3.1A
7.5KW                                4.9A
                                            8.1A
想請問如何根據(jù)空載電流知道該電動機(jī)的功率  謝謝

寫的不錯哦，學(xué)習(xí)啦。
