I don't know if theory alone can explain this well, there are so many variables. When any phase is excited, delta energizes all three coils at a time whereas Wye only excites two. If kv is the same between termination styles the amp draw will be the same, and since kt and amp draw will be the same the motor torque will also be the same.


Change the magnet count or stator count- motor power will change. Change the size of the motor, motor power will change. Change the winding of the motor, motor power only changes in respect to voltage.
