Motor Failure Replace Decision

Motor Management Plan

Motor Failure

Your electric motor has just failed. Should you have it repaired or buy a new one?

Before making your final decision, you must first consider the operating costs involved. The cost of the motor is insignificant compared to the cost of the electricity required to operate it. NEMA Premium® Motors really do save far more than the cost of the motor and keep on saving for years to come.

Determining Your Horsepower Breakpoint

Look at the chart below and locate your annual operating hours on the bottom line. Now find the average cost of electricity at your facility. At the intersection of these lines, go horizontally to the left to find your hp breakpoint for TEFC motors. The example below for 4,000 hours per year at $0.08/kWh indicates it is more cost-effective to simply replace rather than repair all failed standard efficiency motors 75 hp and smaller with NEMA Premium® Motors. Even motors above the breakpoint hp might be worth replacing rather than repairing if you can get a financial incentive.
