Thank You, to everybody who replied.
I was just trying to reinforce my
understanding with motors. My experience
from small to large motor, I have not
seen a motor with 2 power supply or
voltage. I was wondering if there a
new method now that it is supply by
2 power supply voltage, and nine wires
coming from this supply.
Now I know that this thing doesn't exist.
You are all right on your explanation.
Thank You.
