We are a dedicated Servo Motor Department.
Here at ACT, our technicians are artfully trained to diagnose and repair each servo motor using proprietary techniques; this ensures the proper operation of the motor according to the manufacturer’s specifications. Each motor goes through a thorough testing procedure to determine the motor malfunction. This entails a complete teardown, repair, and post-test to bring the motor operation up to proper specs. Each repair will also include a complete evaluation report outlining the motor’s condition upon arrival, with motor tests performed to determine the condition of the stator windings, feedback device, brake, rotor, and bearings.
Winding tests are performed using the Megger ADX4 windings analyzer. The feedback device is tested using proprietary Mitchell Electronics hardware and software equipment to evaluate the feedback device(s) condition. Brake torque is also tested and compared with known data. All bearing fits are measured, recorded, and compared to EASA specifications.
In-Depth Testing Process
- Stator windings are tested using the Megger ADX4 windings analyzer.
- Feedback devices are tested utilizing Mitchell Electronics diagnostic and test system.
- Brake Torque is tested to meet OEM specifications.
- Bearing fits are measured, recorded, and compared to EASA specifications
- All test results are saved, and a full report is sent with every servo motor repair.
Quality Repair Method
- All technicians are required to verify completion of our step-by-step documented repair process and record all test results. This ensures a quality repair is performed.
- All bearings are replaced with NEW bearings
- We test feedback devices to OEM specification by testing counts, signal levels, and memory programs. We also verify the feedback device for correct electrical alignment on the motor.
- In-house machining center that can re-machine motor end bells and shafts.
- Rewinds performed on stator windings that fail Megger ADX4 windings analysis due to insulation degradation, shorts or catastrophic failures.
Our Servo Motor Repair Process
Quality is the focus of all our repairs. Our qualified technicians both evaluate and perform the repairs to your equipment using custom test fixtures designed to validate every repair.
1. Check-In Process
Upon arrival at the repair facility, the servo motor is checked in through a systematic process. This involves documenting the motor’s make, model, and any visible damage or issues. The customer provides details about the motor’s performance problems and any relevant operational history. A unique identifier or work order number is assigned for tracking purposes.
2. Evaluation
Skilled technicians conduct a thorough evaluation of the servo motor to identify the root cause of the malfunction. This assessment includes a detailed inspection of the internal components, such as the encoder, bearings, and wiring. Specialized diagnostic tools may be used to measure electrical and mechanical parameters, helping to pinpoint the specific areas that require attention.
3. Quote
Following the evaluation, a comprehensive quote is prepared for the customer. This quote outlines the cost of the necessary repairs, including parts and labor. The customer is then provided with a detailed breakdown of the identified issues, allowing them to make an informed decision on whether to proceed with the repairs. Any additional recommendations for preventive maintenance may also be included in the quote.
4. Repair
Once the customer approves the quote, the repair process begins. Skilled technicians disassemble the servo motor, replacing faulty components such as damaged wires, bearings, or electronic modules. Careful attention is paid to ensure that the motor is reassembled according to manufacturer specifications. Quality replacement parts are used to restore the motor to optimal functionality. Technicians also address any other issues discovered during the repair process.
5. Testing
After the repairs are completed, the servo motor undergoes rigorous testing to ensure it meets or exceeds the manufacturer’s specifications. This testing involves verifying the motor’s electrical and mechanical performance, checking for proper alignment, and validating the functionality of any integrated feedback systems. Full motor testing capabilities with balance & rewind done in-house. Only when the motor passes these tests is it deemed ready for return to the customer.
6. Return to You
The repaired servo motor is carefully packaged and shipped back to the customer. The return process includes providing the customer with relevant documentation, such as test reports and a summary of the performed repairs. The customer is also informed of any preventive maintenance recommendations to prolong the lifespan of the servo motor. Additionally, tracking information is provided to enable the customer to monitor the return shipment.
ACT provides Servo Motor repairs for all your Servo Motor needs.
