Classification: CPC H  Y | IPC H

Claim 8:
9. A method of manufacturing a rotating electrical machine that comprises:
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,
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,
the method comprising:
a first step of covering a surface of a flat plate made of magnetic material with a filmy sheet member made of thermoplastic resin as non-magnetic material;
a second step of embedding at least a part of each of the conductive members into the filmy sheet member to thereby secure the corresponding one of the conductive members to the flat plate via the filmy sheet member; and
a third step of rolling the flat plate with the conductive members being secured thereto via the filmy sheet member to thereby form the base member having a hollow cylindrical shape.
