Baldor Motors We Repair
What to send us
A photo of the nameplate speeds up quoting. On Baldor motors, the catalog number and spec number identify the exact design. Include the horsepower, voltage and frame size if the nameplate is damaged, a short description of the failure, and how quickly you need the motor back.

New Baldor motors, ready to go
Not every motor is worth repairing. When a standard Baldor is the faster fix, we sell new ones, with Baldor factory stock close by in the Romeoville and Bolingbrook area. Call (630) 283-3569 with the nameplate and we will quote it.
Our Baldor repair process
Incoming inspection
We record the nameplate data and the motor’s condition when it arrives.
Testing
Ground testing, surge comparison and core loss testing identify winding and core problems.
Teardown and failure analysis
We inspect bearings, shaft, rotor, stator and housings to find the cause of failure, not just the symptom.
Written quote
You receive a repair quote, and a replacement quote when a new motor makes more sense.
Repair
Rewinding, bearing replacement, shaft and housing machining, and brake work as required.
Balancing and final testing
before the motor is returned.

Straight answers on Baldor
Q1What on a Baldor nameplate do you actually need?
The catalog number and the spec number. The spec number pins down the exact design, including options the catalog number does not show. A clear photo of the whole nameplate is best.
Q2Is a dead Baldor worth repairing, or should we just buy new?
Small stock Baldor general purpose motors are often cheaper to replace. DC motors, larger frames, washdown and brake motors are usually worth repairing, especially when a new one is not on the shelf. We will quote both so you can compare.
Q3Our motors keep failing. Can you tell us why?
Usually the motor is pointing at something upstream. The most common culprits are incoming power problems, like voltage imbalance, spikes and drive-related shaft currents, and a harsh environment: heat, moisture, dust and washdown chemicals. Misalignment and bearing trouble round out the list. We tear every motor down, find what actually took it out, and tell you, so the replacement does not go the same way.
Q4Is a rewound motor as good as a new one?
In a lot of cases it is better. We rewind with Grade H magnet wire, a higher temperature rating than most shops use, and seal the windings with Elantas varnish. Plenty of our motors leave the shop in better shape than when they left the factory.
