HECO Does Big & Small Electric Motors

09/10/2020

Not all the motors in your facility may be larger motors, and size is not an indicator of how critical a motor may be to your processes. That's why at HECO we've made sure that we can repair and recondition small motors just as effectively as we can large motors.

Repairing Small Motors

Small motors, just like their larger counterparts, need repairs and those repairs aren't necessarily cheaper because the motor is smaller. That's why it's important to make sure you're making the right decision about who you want working on your small motors.

In another post, Electric Motor Repair vs. Replacement - How to Choose?, we talked about a steel company that was sending out 5HP, 1800RPM motor fans for repairs that cost an average of $3000 each -- and they needed about 54 repairs per year on these motors. Oh, and the lifespan of these motors was 6 months. It turns out that they considered these to be emergency repairs, which meant their repair vendor was simply fixing the motor as quickly as possible without regard to what was causing the repeated problems.

That is not a good plan, especially given the expected life of the motor. When there are repeated failures of the same type of motor, either the source of those problems needs to be sought out and addressed or the motor needs to be replaced.

Small Motors: Repair or Replace?

Sometimes it is more cost-effective to replace a smaller motor than it is to repair it. There are several factors that you should take into account when deciding whether to repair or replace an electric motor (small or large!), including ...

  • What caused the motor to fail?
  • How is old the motor?
  • What is the size of the motor?
  • What are the annual operating hours for the motor?
  • What are the capabilities of your repair shop?
  • What will the repair cost?

To be sure, size is a major factor in the choice to repair or replace. If the repair costs for a motor exceed 60 - 70% of replacement cost, then you should replace the motor.
