How To Check Motor Winding Resistance On Single & Three-Phase Motors
Motor Circuit Analysis™ (MCA™) is a test method that determines the true state of health of 3 phase & single-phase electrical motors. MCA™ checks the motors coils, rotor, connections, and more. MCA™ can verify ac motor winding resistance as well as dc motor resistance and determine state of health.

How High Resistance Imbalances Can Damage Your Electric Motors
A small, but critical, motor in a pulp and paper mill exhibits a changing and rising resistive imbalance indicating a power circuit anomaly. If the motor fails, the loss of production costs could be up to $20,000 per hour. Follow along as they test and investigate the problem.

Electrical Insulation Failure
Electrical Insulation is used to direct current through a desired path and prevent it from flowing where it is not desired. Proper electrical insulation is critical to an electric motor’s performance and longevity. Insulation breakdown is one of the most frequent causes of electric motor failure. In electric generators, for instance, 56% of failures originate from electrical insulation damage.

Gear Box Failure on Cooling Tower Induction Motor Fan
The large motors in this power plant are attached to a gear box, which is attached to a cooling fan inside the cooling tower. All components are enclosed inside a shroud, making a visual inspection difficult and costly. A knocking noise, possibly coming from inside the shroud, was detected. But was it the motor or the gear box? Watch the video to learn how the problem was analyzed without disassembling the shroud.

Trending DC Field Inductance in an Aluminum Mill Coil Motor
A critical 600 hp motor was redesigned to 750 hp and was running at 900 hp, which created excessive heat. To avoid catastrophic failure, motor was tested every three weeks. The Megohmmeter reading was normal, so how did they know there was a problem? Watch this video and learn.
