Abstract
An armature coil is formed by welding upper and lower coil conductors each having a coil trunk, a pair of coil arms and a pair of coil extensions. Between an upper coil extension and a lower coil extension to be welded together, a recess is formed. This recess may be formed at the corner between a side face of an upper coil arm which is at the side of the armature core and a radially inner side face of the upper coil extension. The radially inner side face of the upper coil extension has a space against the radially outer side face of the lower coil extension only at the location where the recess is provided, while the radially inner side face except for the recess contacts the radially outer side face of the lower coil extension.
