    摘要: The armature of an engine starter direct current (d.c.) motor comprises a rotary shaft, an aluminum armature coil. The commutator a commutator disposed on the rotary shaft and has a plurality of copper commutator segments each including a main body portion having a sliding contact surface and a connecting portion having an aluminum connecting surface. The aluminum armature coil is electrically and mechanically connected to each of the aluminum connecting surfaces of the commutator segments to form an electrical and mechanical connection therebetween. The electrical and mechanical connection between the aluminum connecting surface and the armature coil is coated with an electrically insulating resin.
