Universal Servo Motor Running Test

Star Automations specializes in testing and servicing AC servo motors. AC servo motors. We have a Universal advanced servo motor testing kit that is used to run tests on various AC servo motors whose OEM drive controllers have proprietary control interfaces. With our advanced testing system, any AC servomotor utilizing a standard encoder, resolver, or hall effect feedback system can be easily and dynamically tested. Additionally, many “complex” or “serial” type feedback servo motors can be tested as well. The servo motors under analysis are load tested to ensure a quality repair every time.

OUR SERVO MOTOR TESTING PROCEDURES

INITIAL EVALUATION

During an evaluation, a visual inspection is conducted on parts such as the shaft, keyway, endbells, terminals, and connectors. A surge comparison or short test follows to check if the stator needs rewinding. An insulation resistance (megger) test is performed on each phase to ensure insulation integrity. Next, a phase balance test using an RMS meter ensures balanced windings and checks the brake if present. The KE test assesses the magnets’ condition. Finally, the feedback device is tested using a Universal Advanced servo motor testing kit.

DISASSEMBLY

After obtaining our prescriptive test numbers, we proceed with a thorough end-to-end deconstruction, examining and refurbishing every motor component from the pulley end (PE) to the opposite pulley end (OPE). We address common servo motor failures by installing new seals to keep contaminants out and replacing both bearings with new or refurbished units that often exceed OEM specs. These steps prevent vibrations and enhance motor reliability and longevity.

CLEANING

Star Automations has adopted ultrasonic cleaning, a method widely utilized across various industries including automotive, aviation, aerospace, medical device manufacturing, and electronic assembly. This advanced cleaning technique enables technicians to closely inspect disassembled parts, detecting even the most minute issues. By employing a specialized solvent vapor mixture, ultrasonic cleaning effectively breaks down stubborn particles and burnt-on contaminants, surpassing the limitations of traditional handwashing methods.

REASSEMBLY

At Star Automations, we specialize in precise and excellent servo motor repairs. Our meticulous disassembly and reassembly, strict torque adherence, and comprehensive testing ensure error-free, fast turnarounds. We prioritize quality assurance with brake torque, release voltage checks, and post-repair functionality scrutiny. Surge and Hipot Tests guarantee longevity and safety, addressing insulation weaknesses proactively. Our focus on performance and safety defines our commitment to reliable, high-quality repairs

FEEDBACK ALIGNMENT

Ensuring precise alignment between encoders and resolvers is crucial for avoiding a cascade of operational issues, ranging from erratic behavior to reduced torque and even complete immobility. To address these concerns effectively, conventional methods fall short. With its innovative digital-first alignment approach, this state-of-the-art tool achieves the coveted 0° position with unmatched precision, ensuring optimal operability. Equipped with advanced diagnostic capabilities, technicians at Star Automations can now identify and resolve issues with unprecedented efficiency. By scrutinizing individual waveforms in detail, they gain deeper insights into system performance, facilitating swift and accurate corrective actions to maintain operational excellence

FINAL TEST

At Star Automations, we prioritize the reliability and performance of servo motors. Each motor undergoing repair is meticulously compared to OEM specifications. Only those meeting our stringent standards are reintegrated into production. Servo motors then undergo a comprehensive closed-loop system test, rigorously evaluating speed and amperage for operational efficiency. Thermal performance is also assessed to ensure durability. This meticulous testing guarantees optimal performance and longevity in the field.
