When the load has no strict requirements on the starting torque of the asynchronous motor and the motor starting current is limited, the motor meets380V/ΔWiring conditions, when the motor is running normally, the stator winding is connected into a triangle to adopt the star triangle starting method. Today, Senli Motor Xiaobian mainly talks about star triangle step-down starting.

       At the start of the motor, the current is very large, but the current will be much smaller after the start, so some high-power motors use the way of buck start.

       When we are wiring, we need to first remove the three connection pieces on the asynchronous motor stator terminal, if not removed it is easy to short-circuit phenomenon, you should knowThree-phase asynchronous motorThe difference between the star and triangle connections is intuitively expressed on this connection piece.

       Second, the asynchronous motor started by the star triangle buck must be a triangle connection motor, if the star connection is used, it will lead to the failure to use the star triangle buck start, here it needs to be noted, because the rated voltage of the star is220VThe rated voltage of the triangle is380VThis represents the rated voltage of each phase winding.

       The star triangle depressurized start, at the start is used220VThe voltage of... After switching to a triangle, the voltage of each phase winding becomes380VIf it is adopted by itself220VTo bear380VThe voltage will cause the burn.

       Of course star connectionThree-phase asynchronous motorThe power is generally small, and the star triangle step-down starting is generally not used.
