Independent Repair Shop. Not Baldor. Not ABB.
Third-Party Repair of Baldor Servo Drives & Motion Controllers
Independent third-party repair of Baldor hardware: servo drives, motion controllers, electronic control boards, and amplifier hardware. Coverage spans pre-2011 Baldor, Baldor-Reliance, and current ABB-era nameplates. The labels changed; the bench work is the same. Backed by a 19,000+ unit in-house inventory we pull aftermarket and donor parts from. NC Servo is not affiliated with Baldor or ABB. Working on this kind of hardware since 1975.
Pre + post-2011 coverage
Older Baldor units, Baldor-Reliance hardware, and current ABB-era drives all serviced.
Servo drives + controllers
Component-level board work on power stage, control boards, and motion-controller I/O.
One-year warranty
Standard on parts and workmanship for Baldor drive repairs and rebuilt units.
Three Nameplate Eras
One drive family, three different labels
Baldor's hardware on the shop floor often outlasts the corporate identity that built it. Below is the short history of how the same servo drive line ended up with three different labels in three different decades.
Pre-merger
Baldor
Original Baldor branding on servo drives, motion controllers, and amplifier hardware. Long American electric and motion-control heritage.
Post-merger
Baldor-Reliance
Combined branding after Baldor and Reliance Electric came together. Same drives, updated nameplate.
2011 - today
ABB-era Baldor
ABB acquired Baldor in 2011. Current production carries ABB branding alongside Baldor on continuing drive lines.
Service Coverage
What NC Servo does with a Baldor drive
Each Baldor drive is opened, inspected, and rebuilt at the component level. Failed parts come from inventory or off donor units, then the drive runs under load on the electronics bench before it ships back.
Motion controllers
Baldor motion controllers and positioning systems. I/O modules, communication interfaces, and encoder feedback circuit work.
Electronic controls
Baldor electronic control boards and amplifier hardware. Component-level board repair, signal-conditioning verification.
Baldor Coverage
Baldor models through the door
We are a small repair shop, not a Baldor distributor. The categories below are simply what comes through often enough to be familiar. If your model number is not on this list, send it anyway. We work on what we can.
Servo drives
Baldor and Baldor-Reliance servo drives across multiple frame sizes. Common bench items: power-stage rebuild and DC-bus capacitor service.
Motion controllers
Baldor motion controllers with I/O modules and communication interfaces. Common bench items: control board work and feedback channel verification.
Discontinued and ABB-era
Older discontinued Baldor units and current ABB-era drives that share Baldor heritage. Donor parts pulled from inventory keep these in service.
Common Faults
What usually shows up on a Baldor repair
A description of the symptom or fault code helps the diagnosis, but a model number is often enough. The categories below cover the kinds of trouble that come in across Baldor servo drives and motion controllers.
| DC-bus and supply | Failed bus capacitors after long service, blown input rectifier diodes, and failed gate-driver supply rails. |
|---|---|
| IGBT power stage | Blown IGBT modules, failed gate-driver circuits, and protection-trip faults on Baldor servo-drive power stages. |
| Control and feedback | Encoder-feedback channel faults, control-board signal drift, and bad I/O on motion controllers. |
| Connector and electrical | Damaged or corroded connectors, cable strain, and contamination on connector pins after years of service. |
Repair Path
From model number to ship-back
Most Baldor jobs follow the same four steps. Lead time varies because some repairs need parts pulled off a donor unit, so we only commit to timing once a tech has the drive on the bench.
Get in touch
Phone or email with the Baldor or Baldor-Reliance model number, the frame size, and a quick note on the symptom or fault code.
Bench review
Once the drive arrives, a tech opens it, inspects the power stage and control boards, and runs it under load on the electronics bench to confirm what failed.
Cost & approval
We call back with the cost and a rough turnaround. Nothing happens without your sign-off.
Repair, test, ship
Failed components are replaced from inventory or off donors, the drive is verified under load, and the unit ships back.
Inventory & Parts Pool
A 19,000+ unit pool with Baldor hardware in it
NC Servo's in-house inventory holds over 19,000 valves and drives accumulated since 1975, including Baldor and Baldor-Reliance servo drive donors. That pool is where the shop pulls aftermarket parts and donor components for older Baldor units that the OEM no longer stocks.
- Aftermarket and donor parts for Baldor servo drives, motion controllers, and amplifiers.
- If we have a rebuilt match for your model, trade in your old drive for a discount on the rebuilt.
- No match on the shelf? We can suggest a comparable Baldor or cross-brand option, or repair yours.
- Rebuilt drives carry the same 1-year warranty as a fresh repair.

Repair vs replace
When component-level repair makes sense versus buying new or rebuilt.
Baldor servo drive faulted out?

FAQ
Common questions about Baldor repair
A few things customers ask before sending a unit in. Anything not covered, give us a call at 734-326-6666.
Is NC Servo affiliated with Baldor or ABB?
No. NC Servo Technology is an independent, third-party repair facility and is not affiliated with, authorized by, or endorsed by Baldor, Baldor-Reliance, ABB Ltd, or any related entities. All Baldor and ABB trademarks are the property of their respective owners.
Do you service Baldor-Reliance and ABB-era Baldor drives?
Yes. Baldor became Baldor-Reliance after the Reliance Electric merger, and the company was acquired by ABB in 2011. We service Baldor drives from before and after the acquisition, including older Baldor units, Baldor-Reliance hardware, and ABB-era branded systems.
Which Baldor products are in scope?
Baldor servo drives, motion controllers, electronic control boards, and amplifier hardware. We do component-level board work on the drive and controller side. Rotating equipment is out of scope.
Can NC Servo recover programs or parameters from a failed Baldor drive?
Most failures are hardware, and the unit comes back working with its program intact. Corrupted programs are rare; if one is already corrupted before the unit reaches us, that's the one thing we can't recover.
How long does a Baldor repair take?
It varies. NC Servo is a small independent shop, and lead time depends on the drive, what is wrong with it, and whether parts have to come off a donor unit. Give us a call once the drive ships in, and we can give a current estimate after a tech has looked at it.
What if the Baldor drive is beyond economic repair?
If the drive is not fixable, we will let you know and help source a replacement: a rebuilt match if we have one on the shelf, or a comparable Baldor or cross-brand alternative.
What is the warranty on a Baldor drive repair?
One year on parts and workmanship for repairs and rebuilt units. Standard exclusions apply for line-side faults, improper installation, and out-of-spec operation. Verifying line voltage, supply protection, and load matching before powering up a repaired drive is recommended.
