Our Phenix variable voltage power supply is capable of running AC, DC, wound rotor, and synchronous motors up to 700hp. This equipment ensures that we can run motors at rated manufacturing specs.

Core Tester

Core loss testing is a quick and efficient method for determining core losses found in the core steel of stators, rotors, and armatures. Core loss is a significant cause of wasted electrical energy is caused by overheating during operation, as well as physical damage. Core loss testing after rebuilding a motor ensures that it is capable of operating at rated efficiency.

Bar to Bar Armature Tester

The bar to bar test is used to test armatures of DC motors without overstressing the group insulation. Two segments with an equal number of bars are compared, and if the two segments are balanced and contain no faults, a single pattern will appear on the display. Faults are located when there is a change to this pattern. The advantage to doing this test is the ability to also locate high resistance carbon shorts.

Surge Testers

The purpose of surge testing is the ensure the top quality of coil turn and insulation, and to ensure that stator coils are similar. This test is also used to diagnose failing or damaged insulation in motors. As insulation deterioration is a leading cause of motor failure, this test helps to detect the early stages of degradation.


Load Tester

Load testing is the process of putting demand on a system or device and measuring its response. This is done to determine a system's behavior under both normal and anticipated peak load conditions. Using this method helps identify maximum operating capacity while pin-pointing which element is causing degradation.
