UL Field Inspections. Yesterday we were greeted at the front door by our UL Inspector for an unannounced field inspectionâ¦surprise! At another facility there might be a cry for alarm, but at Coast Label Company there was no mad scramble, no rush to hide this, or go find that. We just sat him down and asked what he was checking today.

In simple terms, a stator can be defined as the stationary part of an alternator. In order to understand what the stator does, it is helpful to know how a basic electrical system works.The electrical system on most vehicles includes a way to generate, store, and use electricity.An alternator generates power by producing AC (alternating current).n order to understand what the stator does, it is helpful to know how a basic electrical system works.
