SERVO MOTORS

Precision Servo Motor Repairs by SunSource

At SunSource, we provide expert repair services for both AC and DC servo motors used in a variety of applications, including CNC, robotics, and motion control. Our process begins with a thorough disassembly, deep cleaning, and diagnostic testing of the motor’s feedback system and windings. We can also machine bearing journals, keyways, and shafts to OEM specifications, as well as rewind damaged windings efficiently using our computerized winding machines.

Once repairs are completed, we replace all bearings and seals as part of our standard procedure. The motor undergoes load and closed-loop testing with matching OEM drive systems to ensure it performs reliably in its operational environment. A final report is provided, outlining the motor's performance and detailing all repairs performed.

Comprehensive Servo Motor Repair Process

At SunSource, we specialize in the precise repair and restoration of servo motors, ensuring your equipment operates at its optimal level. Our thorough repair process includes:

1. Initial Logging & Tracking: Each servo motor is assigned a unique tracking number to allow for easy monitoring of repair status and progress, ensuring seamless communication with our team.
2. Diagnostic Teardown: Our technicians carefully disassemble the servo motor and conduct a detailed inspection to identify issues such as worn bearings, damaged windings, or faulty encoders. All components are carefully analyzed for signs of wear or failure.
3. Failure Analysis & Reporting: We document the failure causes and provide a detailed report on the findings. This includes an overview of all necessary repairs, parts replacement, and suggested improvements to enhance the motor's performance.
4. Parts Procurement: If any components need replacement, we source high-quality parts from reliable suppliers. We ensure that every replacement part meets OEM standards, helping to avoid future issues and extend the motor's service life.
5. Component Repair & Replacement: Worn bearings, seals, and faulty windings are replaced, and damaged parts like encoders and sensors are repaired or replaced. If necessary, the motor’s wiring and electrical components are also addressed.
6. Reassembly & Testing: Once repairs are completed, the servo motor is reassembled and tested using our advanced testing equipment. We simulate real-world conditions to check for issues such as overheating, improper voltage, or erratic performance.
7. Quality Inspection: A final inspection is conducted to verify that the motor meets all OEM standards. This ensures that it functions at full capacity, including checking its speed, torque, and overall efficiency.
8. Documentation & Delivery: After passing all tests, we provide a comprehensive report detailing the repairs, part replacements, and testing results. The motor is securely packaged and returned to you, fully restored and ready for reinstallation.

This meticulous repair process ensures that your servo motor is returned to service with enhanced reliability, minimized downtime, and optimal performance.

Advanced Testing for Reliable Servo Motor Performance

At SunSource, we apply advanced diagnostic techniques to ensure your servo motors meet the highest performance standards. Our comprehensive testing process includes:

• Speed & Torque Analysis: We measure the motor’s speed and torque under various load conditions to ensure optimal functionality in different operational environments.
• Vibration Testing: We check for abnormal vibrations, which can indicate issues such as misalignment or wear, ensuring smooth operation and reduced risk of failure.
• Signal & Feedback Testing: We test encoder and feedback signals to ensure accurate position tracking and communication with the system for precise movements.
• Power & Current Testing: The motor’s electrical components are assessed for consistent power output and proper current flow, ensuring efficiency and stability.
• Heat Management Assessment: We simulate real-world operating conditions to assess the motor's heat dissipation capabilities, preventing overheating during extended use.

These rigorous tests guarantee that your servo motor will function optimally and reliably in real-world applications.
