A detailed explanation of the common starting methods for electric motors star triangle step-down start
For a squirrel-cage asynchronous motor in which the normal running stator winding is a delta connection, if the stator winding is connected to a star at the start, and then converted to a triangle after the start, the starting current can be reduced and the grid can be reduced. The impact. Such a startup mode is called a star-delta decompression start, or simply a star-delta start.
When starting with the star triangle, the starting current is only one-third of the original starting directly by the delta connection. When starting with the star triangle, the starting torque is also reduced to one-third of the original direct start when the triangle is connected. Star Delta Buck Start is suitable for applications with no load or light load start. And compared with any other decompression starter, its structure is the simplest, the cheapest price, and the equipment circuit maintenance cost is also the lowest. In addition, the star triangle startup method has the advantage that when the load is light, the motor can be operated in a star connection. At this time, the rated torque can be matched with the load, which can improve the efficiency of the motor and save power consumption.
