Control Techniques Servo Motor Repair / Emerson Servo Motor Repair
Control Techniques servo motors are sometimes known as Emerson, or Custom, and are a prominent manufacturer of servo motors. Older models can utilize resolvers, hall switching sensors and DC Tachometers, whereas many newer Control Techniques servo motor models are equipped with Tamagawa encoders. Servotech offers fast servo motor repairs for all servo manufacturers, and we have repaired and refurbished countless Control Technique servo motors.
At Servotech, it is our mission to refurbish your Control Techniques servo motor back to “like new” condition. We stock a massive inventory or connectors, bearings, seals, and feedback devices, and reference a large collection of technical documents, so we can provide you with the very best Control Techniques servo refurbishments. We know that it is critical to not only replace and repair faulty components, but to also have accurate factory data about proper motor performance and specifications. The Servotech team will comprehensively evaluate the condition of your Control Techniques servo motor and ensure that it will be repaired to the proper performance.
The challenge of repairing Control Techniques servo motors is the intricacy and detail-oriented efforts that must be completed. Despite the complexity of repair, we understand that turnaround time is just as vital importance to our customers. Servotech offers the knowledge base and capacity to repair your Control Techniques servo motor quickly and effectively.

1. Control Techniques Servo Motor Evaluation
Servotech inspects all electrical and mechanical parts on every Control Techniques servo motor. During our evaluation, we check and look for:
- Broken or bent connectors
- Fits, both housing and bearing.
- Encoder condition, including encoder bearings
- Worn keys ways, and output shafts
- Broken flanges
- Corroded or defective hardware

2. Motor Repair
After evaluation, we manufacture or repair any problems found during our evaluation, fixing any part that does not meet the factory specifications. Efforts include:
- Rotor repairs including re-magnetizing and re-banding.
- Re-manufacturing of new Control Techniques servo motor end-bells, using the old parts and factory dimensions.
- Repair of all the windings. Both AC and DC servo motors windings are washed, baked and tested.
- Installation of new brushes, brush holders and Bake-O-Lite insulation tubes on DC motors.

3. Preliminary Testing to Control Technique Standards
During assembly, each Control Techniques servo motor repair is meggered multiple times punctuating each step. A typical battery of our tests includes:
- Test to confirm that none of the electrical parts in the servo motor are shorted to ground.
- Test that all AC servo motor stators are surge tested to at least 1500 volts.
- After the baking process DC Servo motor armatures go through a bar to bar test. This test will show if there are any shorts or opens in the winding.
- Test AC servo motor feedback alignment. Test encoders, hall sensors and resolvers.
4. Servo Motor Assembly
During the next phase, your Control Techniques motor is reassembled. Our assembly process improves the internal motor components using:
- High-grade sealed bearings – we feel that each Control Techniques servo motor repair will have extended life with sealed bearings. Unlike standard bearings, sealed servo bearings keeps dirt and contamination from prematurely ruining the bearing races.
- Double lip shaft seals in the front flange – an astounding number of servo motors do not have any seal on the shaft! Coupled with unsealed bearings, that is a recipe for disaster!
- All new seals, O-rings, gaskets and connectors to ensure that your Control Techniques servo motor is protected from liquid contamination.
- Two-part epoxy coating for an added protection – the same coating used on Navy submarines.
