1. A commutator motor comprising:
- a field magnet including a field magnet core and a field magnet winding; and
an armature including a rotary shaft, an armature core fixed to the rotary shaft, an armature winding wound on a plurality of slots of the armature core, and a commutator, wherein the commutator has commutator segments integer multiples of a number of the plurality of slots and an identical number of hooks to the segments, and a connecting-wire between the armature winding and the hooks is bent and shaped toward the rotary shaft at least at a place one of a start of winding and an end of winding of the armature winding.

Abstract
A commutator motor includes a field magnet having a field magnet core and a field magnet winding, and an armature having a rotary shaft, an armature core fixed to the rotary shaft, an armature winding wound on slots of the core, and a commutator. The commutator has commutator segments integer multiples of the number of the slots, and the same number of hooks as the slots. A connecting-wire between the armature winding and the hook is bent and shaped toward the rotary shaft at least at one pace of a start and an end of winding of the armature winding.

4. A method of manufacturing a commutator motor, which motor comprises:
-
a field magnet including a field magnet core and a field magnet winding;
an armature including a rotary shaft, an armature core fixed to the rotary shaft, an armature winding wound on a plurality of slots of the armature core, and a commutator having a hook to which the armature winding is connected, the method comprising the steps of (a) providing a pair of the slots with a winding plural turns;
(b) forming a connecting-wire and providing another pair of the slots with a winding plural turns;
(c) bending and shaping the connecting-wire toward the rotary shaft;
(d) connecting the connecting-wire to the hook; and
(e) repress-fitting the commutator on the rotary shaft while the bent and shaped section of the winding is maintained with a winding-shaping jig. - View Dependent Claims (5, 6, 7, 8, 9, 10)
