Electric Motor Factories

The most common product in electric motor windings is polyesterimide enamelled round copper wire. Its symmetric cross-section runs smoothly on automatic winding machines; Class 180 (H) covers most industrial service conditions. In high-power machines, flat enamelled conductor is used to raise the fill factor.

In motors driven by frequency converters, the very short rise-time impulse voltages cause an uneven voltage distribution across the first turns of the winding and increase partial-discharge risk. Grade 3 build or mica-over-enamel conductor is preferred in these applications. Conductors are produced to IEC 60317-0-1 and IEC 60317-0-2, with tests based on the IEC 60851 series.
