• Use testing equipment including ohm, amp, and insulation testers to diagnose faults in armatures, rotors, stators, and windings.
• Rewire coils, replace bearings, brushes, and seals; reface commutators; machine parts to tolerance standards.
• Reassemble and load-test motors to verify operational performance before release.

Quality, Safety and Documentation

• Maintain shop organization, cleanliness, and strict adherence to safety and lockout/tagout protocols at all times.
• Accurately complete all required paperwork—documenting repairs, parts used, and time spent on every job.
• Report equipment maintenance needs, recurring issues, or potential improvements to management.
• Participate in continuous improvement initiatives and suggest process enhancements to increase quality and efficiency.

Qualifications

• Mechanical and electrical aptitude with the ability to install, disassemble, diagnose, and repair rotating machinery.

• Precision craftsmanship—skill in micrometer and gauge measurements, machining to tolerances, and coil winding.
• Meticulous attention to detail in both repair work and documentation.
