Claim 18:
19. A rotating electrical machine comprising:
a magnetic field-producing unit equipped with a magnet unit including a plurality of magnetic poles whose magnetic polarities are arranged alternately in a circumferential direction; and
an armature which includes a multi-phase armature winding, the armature winding being of a cylindrical shape having a longitudinal center line,
wherein one of the magnetic field-producing unit and the armature is engineered as a rotor whose rotating shaft is retained by bearings to be rotatable,
the armature includes a ring-shaped base member which is disposed integrally with the armature winding and secured to an armature holder, the base member being of a cylindrical shape coaxial with the longitudinal center line of the armature winding and having a peripheral surface in contact with a peripheral surface of the armature winding, the peripheral surfaces of the base member and the armature winding likewise being cylindrical in shape and coaxial with the longitudinal center line,
the armature winding is covered with a molding material along with the base member, and
the armature winding is comprised of a coated conductor in which a surface of a conductor body is covered with a coating.
