| Abstract: | The article introduces the reduced voltage starting principle of the high power motor with 19000kW, working principle and starting characteristic of the thermal resistor, analyzes the main factors which affect the motor starting performance. According to the starting practice and recorded starting curve, it finds out the influ- ence factors of the motor stating including real temperature of thermal resistor and voltage of the power network, which is expected to adjust the parameters reasonably and optimize the starting curve. |
