Almost any industrial activity depends on an electric motor. When repair vs. replace considerations arise, the choice can result in thousands of dollars saved or lost. This is partly due to the direct repair/replacement costs but also as a result of downtime that grinds operations to a halt. Making the right call between electric motor replacement vs. repair is thus extremely vital to minimizing downtime and costs.

Should You Repair or Replace Your Electric Motor?

It’s essential to make time for regular servicing appointments. Preventative maintenance is the most reliable way to keep long-term equipment costs low, as poorly serviced electric motors are a common cause of motor repair and replacement issues. Consider these factors when deciding whether to replace or repair your electric motor:

Electric Motor Repair vs. Replace

Electric Motor Repair vs. Replace
  • Environmental impact: Repairing motors results in less waste by extending the lifespan of existing equipment while reducing demand for new motor manufacturing. It can also help operations meet financial and waste-reduction goals.
  • Lead time: Compare the lead time for repair and replacement. Generally, repairs have a shorter lead time than new motors, which tend to take longer to order, ship, and install in your facility.
  • Extent of damage or wear: If the severity of a motor’s damage is extensive, repairs may be more costly than replacement. Worn brushes, bearings, or capacitors can be cost-efficiently repaired, while major damage to windings or other essential parts could be beyond repair.
  • Cost of repair vs. replacement: Generally, if electric motor repair costs reach 50% to 75% of the cost of replacement, it may be a better idea to replace the motor.
  • Motor age: At some point, motors reach the end of their expected lifespan, where repairs occur more frequently and the one-time cost of replacement is justified. If the motor is relatively new and the cost of repair is reasonable, repair is the better choice.
  • Parts availability: Waiting on parts for outdated motors or uncommon brands can create costly downtime. Replacement parts can even become difficult or impossible to find and result in extensive custom repair work.
  • Energy efficiency: New electric motors are often more energy efficient, resulting in greater long-term energy and cost savings.
  • Performance requirements: Determine whether the motor, once repaired, would meet the output and efficiency requirements of your operation. If not, you may need to replace it.
  • Downtime and lost productivity: Assess the financial impact of motor downtime in your production. Perhaps the downtime is expensive, and it’s more financially feasible to do a quick replacement rather than an extensive repair.
  • Service history: On reviewing a motor’s maintenance history, look for signs of recurring issues. This could make a replacement electric motor the smarter option.
  • Technological upgrades: Replacing your motor with a newer model may be worth the higher cost if you need the enhanced features.
  • Warranty coverage: See if your electric motor is still under warranty because this alone can significantly cut your repair costs.
  • Expert opinion: Motor technicians and engineers can provide a reliable assessment of the motor’s true condition and then suggest the most effective solution.

A cost-benefit analysis using the points above will help determine whether industrial electric motor repair or replacement is the wisest course of action. Compare each choice’s short- and long-term benefits and decide what your cost threshold is where repair is no longer cost-effective.
