Two Minute Tips
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.

Protective Coating for Wire Rope, Chains & Cables
Wirelife Almasol Coating Grease (453-451) is a soft, semifluid formulation designed to coat wire rope as well as moving chain and cable parts to ensure long life and smooth, quiet operation. Its tacky, water-resistant characteristics enable it to adhere strongly to rapidly moving parts and to seal out damaging moisture.

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.

Best Kept Secret in Bearing Uptime
Vari-Purpose Lubricant is cool-running, long-lasting, and water-resistant. It dramatically lengthens grease intervals, eliminates bearing failures, can extend bearing life by up to threefold, and does not harden with age.
