Abstract
A dynamic profiling system for measuring a profile of an outer surface of a moving motor component such as a commutator includes a movable probe assembly having a profile detecting probe and a probe cooling system for circulating a cooling liquid about the probe. The probe cooling system maintains the cooling liquid at a fixed temperature during circulation of the liquid. The detecting probe obtains profile measurement data from the outer surface of the rotating motor component when the motor component is at ambient and hot temperatures. Additionally data is collected while the commutator is rotating up to 4000 revolutions per minute. The system further includes a controller, an analog to digital converter for receiving and converting the data, and a monitor for displaying information processed by the controller. The controller directs a probe positioning device to reciprocally position the probe assembly relative to the moving motor component under test and a protective enclosure encloses the moving motor component while the test is in progress. An aperture in the protective enclosure allows the probe assembly to approach the moving motor component by passing through the aperture …
