  • Patent number: 9209659
    Abstract: An armature for a rotating electric machine includes an armature core and an armature coil. The armature core includes a substantially annular main body disposed in radial opposition to a field of the machine and teeth extending from the main body radially toward the field. The armature coil is arranged between the teeth of the armature core. For each of the teeth, there are formed a protrusion and a pair of claws at a distal end of the tooth. The protrusion protrudes from a circumferentially central part of the distal end of the tooth radially toward the field. The claws extend, respectively on opposite circumferential sides of the protrusion, from the distal end of the tooth toward the field. Each of the claws has a smaller width at its distal end than at its proximal end and is arcuate-shaped so as to engage with and thereby retain the armature coil.
