Direct Current Motor

摘要

The purpose of the present invention is to provide a direct current motor wherein the number of coil-connecting wires that cross the outer surface of a coil end part is reduced. In a direct current motor that is provided with an armature that has a plurality of armature slots and has an armature coil that is wound so as to span two armature slots that are separated by a fixed number of armature slots, a lowermost layer of a coil end part is provided with at least four armature coils that are wound through other armature slots so as not to coincide with the wound armature coil, and a layer above the four armature coils that are wound on the bottommost layer is provided with at least four armature coils that are wound in the same manner as the four armature coils.

主权项

1. A direct-current motor including an armature including a plurality of armature slots and an armature coil wound to stride over two of the armature slots away from each other with a certain number of the armature slots interposed therebetween, the direct-current motor comprising:
at least four armature coils each wound on a lowermost layer of a coil end portion without overlapping with the armature coil wound through the different armature slots, wherein, on a higher layer than the four armature coils wound on the lowermost layer, at least four armature coils wound in an equal pattern to that of the four armature coils are provided.
