Amp side Delta, Motor side Wye or vice versa <-- Would it be fine for a sinusoidal setup?

And silly question but would this create phase shift of 30 degrees? (I guess not because unlike transformers, there is no magnetic field envolved..)

BTW are sinusoidal servos typically WYE connected or Delta connected? How about Sanyo servos?

My understanding is that Wye configuration gives high torque at low rpm, but not as high top rpm <-- So I would think Wye is perfect for servo...

Well, thank you in advance for your expert advice and have a great day!
