What do Electric Motor, Power Tool, and Related Repairers do?

  • Measure velocity, horsepower, revolutions per minute (rpm), amperage, circuitry, and voltage of units or parts to diagnose problems, using ammeters, voltmeters, wattmeters, and other testing devices.
  • Record repairs required, parts used, and labor time.
  • Reassemble repaired electric motors to specified requirements and ratings, using hand tools and electrical meters.
  • Maintain stocks of parts.
  • Repair and rebuild defective mechanical parts in electric motors, generators, and related equipment, using hand tools and power tools.
  • Rewire electrical systems, and repair or replace electrical accessories.
  • Inspect electrical connections, wiring, relays, charging resistance boxes, and storage batteries, following wiring diagrams.
  • Read service guides to find information needed to perform repairs.
  • Inspect and test equipment in order to locate damage or worn parts and diagnose malfunctions, or read work orders or schematic drawings to determine required repairs.
  • Solder, wrap, and coat wires to ensure proper insulation.
  • Assemble electrical parts such as alternators, generators, starting devices, and switches, following schematic drawings and using hand, machine, and power tools.
  • Lubricate moving parts.
  • Remove and replace defective parts such as coil leads, carbon brushes, and wires, using soldering equipment.
  • Disassemble defective equipment so that repairs can be made, using hand tools.
  • Lift units or parts such as motors or generators, using cranes or chain hoists, or signal crane operators to lift heavy parts or subassemblies.
  • Weld, braze, or solder electrical connections.
  • Reface, ream, and polish commutators and machine parts to specified tolerances, using machine tools.
  • Adjust working parts, such as fan belts, contacts, and springs, using hand tools and gauges.
  • Clean cells, cell assemblies, glassware, leads, electrical connections, and battery poles, using scrapers, steam, water, emery cloths, power grinders, or acid.
  • Scrape and clean units or parts, using cleaning solvents and equipment such as buffing wheels.
  • Rewind coils on cores in slots, or make replacement coils, using coil-winding machines.
  • Cut and form insulation, and insert insulation into armature, rotor, or stator slots.
  • Set machinery for proper performance, using computers.
  • Drain and filter transformer oil and refill transformers with oil until coils are submerged.
  • Position and level battery cells, anodes, or cathodes, using hoists or leveling jacks, or signal other workers to perform positioning and leveling.
  • Verify and adjust alignments and dimensions of parts, using gauges and tracing lathes.
  • Test equipment for overheating, using speed gauges and thermometers.
  • Bolt porcelain insulators to wood parts in order to assemble hot stools.
  • Pour compounds into transformer-case terminal openings in order to seal out moisture.
  • Test conditions, fluid levels, and specific gravities of electrolyte cells, using voltmeters, hydrometers, and thermometers.
  • Clean, rinse, and dry transformer cases, using boiling water, scrapers, solvents, hoses, and cloths.
  • Inspect batteries for structural defects such as dented cans, damaged carbon rods and terminals, and defective seals.
  • Steam-clean polishing and buffing wheels to remove abrasives and bonding materials, and spray, brush, or recoat surfaces as necessary.
  • Test battery charges, and replace or recharge batteries as necessary.
  • Repair and operate battery-charging equipment.
  • Add water or acid to battery cell solutions to obtain specified concentrations.
  • Sharpen tools such as saws, picks, shovels, screwdrivers, and scoops, either manually or by using bench grinders and emery wheels.
  • Seal joints with putty, mortar, and asbestos, using putty extruders and knives.
  • Hammer out dents and twists in tools and equipment.
