why the motor running in delta connection ? it can be in star?

Answer Posted / silamparasan p.

Because the voltage in star connection is Vph=VL/square
root of three.
But in delta connection Vph=VL.
So in star connection is only for starting a motor.
But to run a motor through a delta winding. Becaus then
only full voltage given to motor and it will run in full
speed.
