Abstract
An armature for a motor comprises a winding and a commutator. Each commutator segment has a brush contacting portion and an integral terminal portion connected to a connector portion of the winding. A commutator base includes housings which receive the terminal portions and which have slots for positioning the connector portions of the winding relative to each housing. Each terminal portion has a slot which straddles and grips the connector portion positioned relative to a respective housing. At least one and preferably all terminal portions have two slots arranged side-by-side so that the two side-by-side slots of one of the terminal portions can straddle and grip the lead end and tail end of the winding, respectively.
