What Electrical Machine Winding covers

Electrical Machine Winding in Electrical Installation Technology Level 4 covers taking a rotating machine apart, rewinding it and rebuilding it for testing. You start by recording machine and winding data, applying safety measures, selecting tools and disassembling the machine parts. The winding outcome covers safety, tool selection and installation procedures, from preparing coils to laying them in the stator slots and curing the windings. Assembly then brings back the rotor and stator, bearings and bolting, with winding data checked and the area kept clean. The unit finishes with testing: setting up test equipment, choosing test parameters, running continuity, polarity, insulation resistance and voltage and current balance tests, and compiling test reports.

Careers after Electrical Machine Winding

Rewinding returns a failed motor or generator to service, and this unit trains you for that repair work.

  • Motor rewinding workshops in Nairobi - You record winding data, strip the machine, prepare and lay coils, cure the windings and reassemble. You are paid a wage or a rate per machine.
  • Factory maintenance sections in Athi River - You disassemble, test and rebuild rotating machines and compile the test report for the maintenance record. You are employed on a monthly wage and keep the housekeeping standard of the section.
  • Pump and borehole service firms in Kajiado - You service the motors that drive pumps, fitting and lubricating bearings and testing before the machine goes back.
  • Self-employed rewinders in Nyahururu - You take rewinding jobs from local workshops and farms, quote from the winding data and earn per machine, which gives you steady work between larger contracts.

Recorded winding data is what lets you rebuild a machine to its original design.
