Assignee: DENSO CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A rotating electrical machine comprising:
a field generator that includes a magnet unit, the magnet unit having a plurality of magnetic poles whose polarities are alternately arranged in a circumferential direction of the rotating electrical machine; and
an armature that includes a multi-phase armature winding and a base member to which the multi-phase armature winding is secured, the base member being made of magnetic material, and having:
a hollow cylindrical or a cylindrical shape;
an inner peripheral surface; and
an outer peripheral surface,

one of the field generator and the armature serving as a rotor of the rotating electrical machine,
the multi-phase armature winding comprising a plurality of conductive members that face the field generator and are arrayed at given intervals away from each other in the circumferential direction,
each of the conductive members having a base-member side peripheral surface,
the armature further comprising a filmy sheet member arranged to cover one of the inner peripheral surface and the outer peripheral surface of the base member,
the filmy sheet member being made of thermoplastic resin as non-magnetic material, and having a field-member side peripheral surface,
each of the conductive members having at least part embedded in the filmy sheet member in a radial direction of the rotating electrical machine to thereby arrange the base-member side peripheral surface to be radially closer to the base member than the field-generator side peripheral surface of the filmy sheet member is.
