Repair or Replace?

Motor Repair Pros and Cons

Determining whether to repair or replace a motor is a critical decision for facilities both small and large.  Decision makers must weigh the pros of replacement (improved efficiency, fewer breakdowns/production halts) versus the pros of repair (short-term cost savings).  

EISA does not require that non-compliant motors be put out of service, only that most new general purpose 1-200 hp motors produced and sold in the United States must meet NEMA Premium Efficiency standards.  This means motor repair may be a viable option in some situations, but it's important to understand the real cost of repairing lower-efficiency motors.  

  • For smaller motors, buying new costs less than rewinding
  • Larger premium efficiency motors offer fast payback when compared to rewinding costs
  • Rewinding typically results in an efficiency loss of 1%, which increases energy costs*
