| Abstract: | This paper analysed the main reason for the breakdown of smallscale moter A Research has been carried out and opened up a small-scale moter safeguard. It has adopted the voltage made when any phase of the three electric lacking,and current deviate figure as control signal. It can directly protect and control small-scale moter(below 1. 5KW) Mean while it has apdopted overload and stator winding overtemprature circuit, which will cut off power supply to protect moter, when the moter over temperates. |
