• Conduct electrical tests, including insulation resistance, winding resistance, continuity, and other appropriate tests before and after rewinding.
• Identify winding faults, insulation failures, short circuits, open circuits, and earth faults.
• Inspect bearings, shafts, cooling fans, terminal boxes, and other motor components and report defects requiring attention.
• Assist with bearing replacement, rotor balancing coordination, and other related repair activities within the scope of competence.
• Ensure that rewound motors meet specified electrical, mechanical, and operational requirements before release.
• Maintain accurate records of motor specifications, winding data, test results, repairs, and materials used.
• Maintain winding tools, testing equipment, and workshop machinery in good working condition.
• Follow established procedures for handling electrical equipment, insulation materials, varnishes, and other workshop chemicals.

• At least 2–3 years of practical motor rewinding and repair experience, preferably in a steel manufacturing, mining, or heavy industrial environment.
• Demonstrated practical experience in rewinding low-voltage industrial motors.
• Knowledge of winding patterns, coil design, insulation systems, motor connections, and electrical testing procedures.
• Experience with three-phase induction motors and familiarity with medium-voltage motors will be an added advantage.
• Experience in generator and alternator rewinding will be an added advantage.

Competencies and Skills

• Strong practical skills in electric motor dismantling, rewinding, assembly, and repair.
• Knowledge of motor winding calculations, coil pitch, winding layouts, and connection diagrams.
• Ability to identify winding faults and determine appropriate repair methods.
• Proficiency in using insulation resistance testers, Multimeter, winding resistance meters, and other relevant testing equipment.
• Understanding of insulation classes, winding materials, varnishing, and motor protection.
• Ability to interpret motor nameplates, winding diagrams, and technical specifications.
• Knowledge of motor testing, fault diagnosis, and quality control procedures.
• Good attention to detail and commitment to precision workmanship.
• Strong troubleshooting and problem-solving skills.
• Ability to work independently and meet urgent repair deadlines.
• Knowledge of workshop safety, electrical isolation, and safe handling of materials.
• Good communication, teamwork, record-keeping, and organisational skills
