I have a G-5500 that sometimes will not turn clock wise(CW) but will
turn counter clockwise (CCW) OK. When it is working OK in both
directions each winding (CW and CCW) measures about 4.4 Ohms in the
shack. When it will not turn CW that winding measures about 2.2 ohms
(The CCW winding still measures 4.4 ohms).
The Controller is fine, so the problem is in the motor.
Does this motor have brushes?
Any thoughts on what the problem might be?
