How Poor Power Quality Can Damage Your Motors

  • Uncategorized

If you want to get the most out of the motors in your facility, it is important to keep them well maintained. Aside from that, it is also important to keep your power line clean from distortion. Distortion can shorten the operating life of your machinery leading to premature aging.


The power fed to your motors should be free from harmonics, sag or any form of distortion that can affect its operation or damage it. One common cause of motor damage is torque shocks. This happens when the power line momentarily fluctuates to a level low enough to open the controller contacts and then suddenly the power returns to a normal level. The back EMF from the motor and the power from the line counteract each other causing jitters which can damage the motor and the load connected to it. It is a good idea to invest in 
electrical test equipment to help reduce power line distortion and prolong the operating life of your equipment.
