Answer Posted / saurabh
During Design it self it is take in consideration
As Power = Torque x Angular Velocity(RPM)
So for same RPM(say 1500 rpm), for Same Input Voltage
1) In star connection Torque will be less hence Power
output will b less
2) In Delta Connection Toruqe will be More hence Power
output will b more
as far as HT motors are concern, in order to limit inrush
current star connection could b given.
