Investing in a quality motor comes with significant costs, and ensuring its longevity and optimal performance is crucial. When faced with motor issues, selecting a repair shop that delivers quality work at a fair price becomes paramount. This article outlines essential factors to consider when choosing your electric motor repair partner.
- Comprehensive Motor Inspection & Repair: A reputable motor repair shop should conduct a thorough battery of tests to guarantee the proper functioning of your motor. Look for a facility capable of:
- Balancing the rotors.
- Identifying open rotor bars.
- “Mic” testing the bearing fits.
- Conducting surge tests on the motor.
- Performing core loss tests and providing detailed reports.
- Inspecting bearing races for fluting or other damage.
- Conducting a comprehensive post-repair motor test.
- Implementing full tear-downs and inspection reports for large motors.
- Adherence to Green Motor Practices: Choose a repair partner that follows environmentally friendly motor practices to preserve and enhance motor efficiency. Certification as a green motor facility ensures adherence to best practices, including pre and post-wind core tests to maintain core losses below 6 watts/lb. This certification is often required for rebates from utilities like Rocky Mountain Power.
- EASA Accreditation: Ensure the repair shop holds accreditation from the Electrical Apparatus Service Association, Inc. (EASA). EASA accreditation signifies strict compliance with the organization’s rigorous standards, covering calibration, training, and best practices outlined in EASA AR100. Request to see the EASA accreditation certificate, as it attests to the shop’s commitment to quality and reliability.
- UL Certification: For motors used in hazardous locations or those designated as explosion-proof, UL certification is indispensable. A repair shop must pass a meticulous 51-point inspection, and technicians need specialized training to provide this certification. Verifying UL certification ensures the shop’s capability to handle motors with stringent safety requirements.
- Bearing Manufacturer Certification: Look for certifications from bearing manufacturers, affirming that the repair facility adheres to best practices in bearing inspection, handling, installation, and testing. These certifications, requiring manufacturer training and regular facility audits, add an extra layer of assurance to the repair process.
In conclusion, when selecting an electric motor repair partner, prioritize a shop that excels in comprehensive testing, adheres to industry certifications like EASA and UL, and follows environmentally conscious practices. These considerations will safeguard your investment and ensure the longevity and efficiency of your electric motor.
