ABSTRACT:
A cylindrical armature has a rotor ring firmly fitted on a shaft, and an armature winding arranged cylindrically and coaxially with the rotor ring and having at least a uniform inner cylindrical insulating layer in closed contact with the inner peripheral surface of the cylindrical armature winding, one end of the armature winding being fixed on the outer peripheral surface of the rotor ring. The outer peripheral surface of the rotor ring, through which the armature winding is coupled with the rotor ring, has grooves knurled at almost the same angle as the angle at which a filament constituting the inner cylindrical insulating layer is wound, whereby a reinforcing layer is formed integrally with the inner cylindrical insulating layer within the knurled grooves, when the filament is wound up.
