Aspects & Defects of Commutator Skins Technical Guide

Inside every electric motor is an essential component known as a commutator. Without a commutator, the motor is unable to produce torque, and thus will not function properly. Commutators are susceptible to a number of defects that can originate from a variety of causes—making it difficult to pinpoint the problem.

Renown Electric’s free technical guide discusses some of the most frequent commutator defects, their causes and how to recognize them, as well as specific information on defects including:

• Erosion
