A new measurement process and tool is to be developed to improve the existing method for measuring runout on the commutators of brushed DC product.

After an armature is manufactured, the commutator is inspected by placing the completed rotor assembly in one of several non-standard measurement fixtures. An indicator is then positioned on the commutator. A trained operator proceeds to rotate the armature while taking runout and bar-to-bar measurement at various positions along the length of the commutator.

This existing process is slow, costly, and unreliable. For these reasons, there is substantial economic pressure to develop a superior method for measurement. The new method will need to be consistent, operate quickly, and produce readings that are more reliable.

Upon completion and implementation, the new process and associated tooling will significantly reduce the production delays and costs associated with the existing method.
