I understand there are different types of induction motors. We use single phase 2 pole and 4 pole cap run motors which have a pretty good balance between forward and reverse torque. We are able to get motors where they adjust the coils to get the forward and reverse toque to be different, up to 20% different in some cases (say CW is 20% more torque than CCW) all without changing the frame size nor as, I understand, the amount of copper used.
So the question is: Can you wind a motor so that it is unidirectional? Can you cut the copper use in half vs. a standard dual direction motor? Or go down in frame size for the same horsepower motor? What exactly do they do to the motor windings when they have more torque in one direction?
Thanks!
