Inductive Imbalance – Part 2

In the previous Tip of the Week, we discussed how inductive imbalance can vary between motors. This week we will discuss how to use the data from the Rotor Influence…

Inductive Imbalance – Part 1

The Stator, Rotor, and Air Gap fault zones can be evaluated in the AC Standard Test by evaluating the Phase-to-Phase Inductance measurements and the associated Inductive Imbalance. An increase in…

Let’s Get The Trade Show on the Road!

With the Pandemic in the rear-view mirror, a major reliability milestone will be accomplished starting this weekend at the Annual EASA Convention in Ft. Worth, TX. A live trade show where…

DC Coil Change in Inductance

In the last Tip we discussed changing the test frequency to ensure the MCEmax® test equipment was optimized for testing DC or synchronous motor field poles. Continuing with the theme…

Change The Frequency – Change The Range

When testing de-energized synchronous or DC motor field poles with the PdMA MCE® remember that different sized field coils with different numbers of turns have very different inductance values. Although…

Servo Motor Troubleshooting

Robotics powered by servo motors are in every aspect of manufacturing from the automotive to pharmaceutical industry. Although it is important to acquire a baseline and acceptance test for Fault…
