ABSTRACT:
A rotor for use in an induction type a.c. generator and a method for fabricating the same are disclosed. The rotor comprises pole pieces having pointed ends at their peripheries, the pointed ends of one pole piece and the pointed ends of the other pole piece alternating in position and serving as, alternately, north and south magnetic poles; a core or yoke disposed between the pole pieces to magnetically coupling the pole pieces; an insulating bobbin disposed on the core or yoke and between the pole pieces; and an exciting coil wound on the bobbin cylindrically. The core or yoke is in the shape of a barrel and the insulating bobbin is forcibly mounted on the barrel-shaped core by the application of pressure.
