Commutators: Diagnose Comm Conditions

Helwig has developed drawings showing what a good commutator should look like as well as what comms with problems look like. Helwig has also described specific fault causes for each of the problem comms so you will know where to go to resolve the root cause. Brush Spring Tension tolerances are also provided for different applications. (Be sure to use the Zoom Tool to enlarge the graphics and text)
