Reducing motor costs through chemistry

Existing technologies that can now be applied to the electric motor industry to reduce costs while improving performance and quality are discussed. Emphasis is placed on chemical processes used for weight addition balancing of armatures and new resins for trickle impregnation and banding of wound armatures and field coils. UV curable, highly filled resins provide continuous automated and manual balancing operations while "heatless" or "chemical" cured polyesters provide compact low cost inline processing of wound coils
