ABSTRACT:
A rotor insulating core for miniature motors comprising a stator having a field-forming permanent magnet, a rotor having a rotor winding wound on a rotor core fixedly fitted to a motor shaft; an insulating core being disposed on the surface of the rotor core; and the rotor winding being wound on the rotor core via the insulating core, in which the insulating core consists of an insulating end-face portion covering the end face of the rotor core and an insulating rib covering the side of the rotor core; both being integrally formed; the insulating rib is formed in such a fashion as to have a thickness smaller than the insulating end-face portion and a predetermined length, and disposed in such a manner as to cover the rotor core on which the rotor winding is wound.
