How to Choose the Right Replacement Electric Motor

As economic problems continue to burden the majority of Americans, an increasing number of homeowners are turning to do it yourself solutions to help save money. One of the easiest ways to do this is to install your own replacement electric motors.

There are any number of reasons why you may need to replace an electric motor, the simplest being that it simply wears out over time. Deciding to replace your own motor is generally the easy part. The difficult part comes when you try to find the accurate replacement motor.

Most websites that sell electric motors have search functions allowing you to look for your specific motor. But, if that's not available, or if the motor you're looking for no longer exists (sadly, this happens), then you need to proceed to the next step.

The next step is to cross-reference the manufacturer's model number. Basically, you're looking for a motor that matches the exact specification of your existing motor, even if the two aren't made by the same manufacturer. You can find the model number to cross reference on the motor plate, a small metal plate attached to your motor with the motor information.

But what if there is no cross-reference? What then?

At that point, your best option is to contact the company selling electric motors and give them the list of identifying specs for your motor. Those specs are HP, Volts, RPMs, Amps, Rotation, Number of Speeds, Number of Phases and Service Factor as well as physical dimensions and mounting information.
