Explain how to check for proper contact pressure using a simple resistance test.

What will be an ideal response?


To check for proper contact pressure, use a simple resistance test. With the power off, measure the resistance from the rotor segment to the associated brush pigtail with normal pressure applied. The reading should be very low ohms. If increasing pressure of the brush to the commutator significantly reduces ohm value, then brush pressure may be a problem.
