Machine winding is one of the most specialised and least-known trades in Sri Lanka's engineering sector. Behind every repaired industrial motor is a skilled winder who rebuilt its heart. The work is precise, satisfying, and occupies a niche that few people master. Career progression to workshop ownership is realistic for those with entrepreneurial drive. The trade-off is that it is specialised, workshop-based, and physically repetitive — but for those who enjoy precision craft work in a quiet industrial setting, it offers a stable and respected career.”
A Day in the Life
Winds coils and windings for electric motors, transformers, generators, and solenoids using winding machines and hand techniques, following winding specifications to produce components that meet required electrical and mechanical performance.
- Read winding data sheets — number of turns, wire gauge, pitch, connection type (delta/star)
- Set up winding machine with correct bobbin, coil former, or jig for the job
- Wind coil sections with enamelled copper wire to specified turn count and layer arrangement
- Apply interlayer insulation (Nomex, Mylar, varnished cloth) between winding layers
- Wind transformer primary and secondary coils and assemble onto core
- Vacuum impregnate completed coils with varnish and cure in oven
- Test finished windings — resistance (DCR), insulation resistance (Megger), turns ratio (transformer)
- Record winding details on job cards and update repair workshop register
Work Environment
Motor and transformer repair workshops, electrical machine manufacturing facilities, and transformer manufacturing plants across Sri Lanka. Workshops handling varnish impregnation and oven curing can have strong solvent fumes — ventilation and PPE are essential. Precise, detail-oriented work requiring patience and accuracy. Employers include motor rewind shops (Colombo, Gampaha, Kandy), transformer manufacturers, and CEB/LECO repair facilities.
Typical hours: 45h/week · WLB score 7/10 · OCCASIONAL overtime
Generally stable workshop hours with overtime during peak repair periods. No emergency call-outs. Clean, indoor, seated work environment compared to most engineering trades.

Top Markets
Market Outlook
STABLE
Steady demand from industrial motor repair and transformer remanufacturing. Sri Lanka's extensive industrial sector (FTZ, cement, food processing, rubber) generates a continuous flow of burnt and failed motors requiring rewinding. This is a niche, specialised trade with limited competition from imports.
Hiring: LOW
STABLE
Machine winding is a specialised trade in global demand wherever electrical machines are repaired or manufactured. EASA-member repair shops globally employ qualified winders. Gulf industrial facilities offer overseas opportunities.

Job Security (SL)
MEDIUM
Automatic CNC winding machines are used for mass production of standard coils. However, repair rewinding of non-standard motors and transformers still requires skilled hand-winding and problem-solving that automated machines cannot replicate.

Mental Health Risks
How to Mitigate
- Use adequate extraction ventilation in varnish impregnation areas
- Take regular breaks from precision winding to reduce eye and hand fatigue
- Wear chemical-resistant gloves when handling varnish
- Use proper labelling on all winding data sheets to prevent errors
