Abstract

Electric motors where the commutator incorporates an annular array of individual Cu strips clamped by dovetail segments along their lower edges. The strips are insulated by coating the clamping flanges, the core body and/or the strips with an insulator which maintains a good bond strength from sub-ambient temps. to 180 degrees C, pref. ceramic or enamel or plastic coatings, esp. epoxy resins. Coated components are quicker to assemble and more durable in service or under repair than assemblies using separate inserts, e.g. mica, for insulation.
