Is it cheaper to rewind or replace a failed motor?

As a provider of new electric motors, along with our 45 years’ experience in motor rewinds, we’re often asked if it’s cheaper to repair or replace a failed motor.

In the case of smaller motors, lower manufacturing costs means that buying new tends to be more economical than a rewind. When considering larger motors, the general rule is that the greater the frame size, the cheaper it is to opt for a rewind rather than a replacement. In fact, the cost difference can be as much as 40% when it comes to frame sizes of 450.

It’s also important to consider the following:

Has the motor been built to a bespoke design?

Specialist motors will almost always be cheaper and quicker to rewind than replace as they can take months to be built and delivered.

Is the motor suitable for the application it’s being used for?

A motor incorrectly used will continue to fail despite rewinding, so a replacement should be considered.

Is there severe damage to the stator core or rotor?

In this instance the cost of repair could exceed the price of a new motor, so advice should be sought.

Is there evidence of catastrophic failure?

Should this be the case, then a complete overhaul may be required to get the motor to its original operating standard which could make replacement the better option.
