Abstract: A stator includes a hollow cylindrical stator core, a stator coil and an outer cylinder. The stator core is comprised of a plurality of core segments that are arranged in a circumferential direction of the stator core to adjoin one another in the circumferential direction. The stator coil is mounted on the stator core. The outer cylinder is fitted on a radially outer periphery of the stator core. The outer cylinder has, at least, a protruding portion and a non-protruding portion. The protruding portion protrudes radially inward to include an abutting part that abuts the radially outer periphery of the stator core. The non-protruding portion extends, without protruding radially inward, to define a radial clearance between the radially outer periphery of the stator core and a radially inner surface of the non-protruding portion. The protruding and non-protruding portions are continuously formed in an axial direction of the outer cylinder.

Abstract: A stator includes a hollow cylindrical stator core comprised of a plurality of stator core segments and an outer cylinder fitted on the radially outer surface of the stator core. The stator core has a recess formed in the radially outer surface and the recess has an engaging wall surface that extends in both the axial and radial directions of the stator core. The outer cylinder has a fastening portion for fastening the outer cylinder to the stator core. The fastening portion is formed to be partially surrounded by a plurality of first slits and a second slit. The fastening portion is bent radially inward to have a second slit-side end part thereof received in the recess of the stator core. Further, the second slit-side end part of the fastening portion has a distal end engaging with the engaging wall surface of the recess of the stator core.

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.
