Given two 3-phase brushless DC motors with the only difference being that one is wound delta, the other Y with center grounded, would I expect to see high frequency voltage-current harmonics to be significantly different between the two?
So in each case the measured terminal to terminal phase resistance and inductance would be the same, the number of poles and PM magnet geometry would be the same,the effective torque constants would be the same, the frame size would be the same, and the drive would be the same.
Realizing of course that making all these other factors the 'same' is a hypothetical situation, and may not be physically realizable.
