Abstract
The armature of a motor comprises a core constituted by assembling a plurality of split core members. Each split core member has at least two teeth. The method for manufacturing the armature comprises the steps of: winding a conductive wire on each tooth of each split core member to form a first coil on the teeth; spanning the conductive wire extending from a winding finishing end of the first coil from each tooth to the other tooth; winding the conductive wire on the tooth to which the conductive wire is spanned to form a second coil on the first coil; joining a winding starting end of the first coil and a winding finishing end of the second coil in each tooth to form a single coil; and mutually assembling the plurality of split core members each comprising the coils. As a result, productivity is improved, while reducing size.
