Motor Overload
Motor overloads occur when motors are drawing too much current. The main issue with excess current is that it creates heat which degrades the insulation surrounding the conductors that creates stator magnetic field.

Service Factor of Motor’s & Cables
The motor and associated cabling have service factors to consider for your process environment as does the equipment you use to monitor your uptime. Variables to consider when replacing your motor and cabling are operating environment temperatures, conditions of process (wet, dry, dirty, etc.) and the process load.

Prevent Motor Failure by Keeping Your Motors Clean
One of the easiest ways to prevent premature electric motor failure is to keep your motors clean and free of foreign contaminates. Many electric motors are fan cooled. When contaminates start to build up around the motor, air flow becomes restricted and reduces the ability for the fan to cool the motor which dramatically reduces the life the of winding’s insulation due to the increase in heat.

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.
