MULTI-TURN WIRE ARMATURE COILS

摘要

This invention relates to an improved armature for a four pole wave wound direct current machine and also to a method for winding the armature for such a machine. A plural turn winding is free formed or wound in place to substantially a final shape with two ends spaced for connection to commutator segments spaced substantially 180 DEG apart on the armature and with at least four sides defining at least two open turns. The winding sides are spaced for engaging slots in the armature core which are spaced substantially 90 DEG apart. The winding is initially free formed and the turns are separated as necessary to insert the winding on the core and to position the winding sides in their assigned slots in the armature core.
