The fully-automated unit performs the required set of tests that motor manufacturing and rebuild shops need for quality assurance and control. AC hipot, DC hipot, surge and resistance tests are standard.

In operation, an armature to be tested is loaded onto the armature indexing stand. This ruggedized, custom built, armature test fixture enables quick and safe connection of an armature to the system. Since many armatures are heavy and cumbersome, the purpose of this fixture is to provide a quick connection of armatures to the tester and provide a higher degree of safety to the operator. The armature is rotated by a rubber drive wheel, which is in contact with the armature and is propelled by a computer-controlled stepper motor. Usually, one or two optical sensors are used to sense the commutator slots as the armature rotates. This fixture is designed for years of heavy-duty operation in a manufacturing environment.
