Helpful hints to prevent motor damage

July 17, 2004
  • Minimize the distance from the drive to the motor.

  • If the VFD is run much at a single speed, arcing through the bearings in the same place can deteriorate them. Use insulated bearings or shaft ground bushings.

  • Make sure motors can handle 3.1 times the line voltage at a 0.1 microsecond rise time.

  • In constant-torque applications, at too low a speed, a TEFC motor will overheat. Define your parameters to avoid this.
