Easy Motor Testing Procedures
Professionals in the industries of manufacturing, power generation and water rely on electric motors to complete their objectives. To remain efficient, it is essential that motor-based systems stay in peak operating condition. A sudden motor failure can occur when you least expect it, so understanding procedures for fast motor testing will help you maximize uptime.

Stator Inter-Turn Stress with Electrical Signature Analysis in Variable Frequency Drive Applications
Incorrect settings in a Variable Frequency Drive (VFD) application have an impact on the windings of an electric motor. When a drive is not set correctly, or not tuned when not using straight volts/hertz settings, stresses occur between the turns in a winding. In some cases, this will appear as small Partial Discharges (PD), and in others it can be increased leakage between turns. When these conditions occur, they introduce small current discharges that effect the air gap magnetic field of the motor.

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.
