In an effort to obtain additional power from an AC motor, a reduction in coil head temperature was needed. Furthermore, there are additional considerations, such as safety and reliability that need to be taken into account when developing a coil head reduction plan. Three possible solutions were prototyped and tested: a highly emissive paint, a thermally conductive polymer, and the utilization of heat pipes. Each idea was tested to determine the reduction in coil head temperature. Of these designs, the use of a highly emissive paint on the internal surface of the motor’s end cap, allowed the most heat to be dissipated. For $4, this solution yielded a 1.8°C decrease in coil head temperature.
