ABSTRACT:
A flat miniature dynamoelectric machine comprises a flat rotor with an assembled coreless coil, a commutator having an exposed portion for sliding contact with brushes and integrally carrying the rotor, a shaft on which the commutator is mounted together with the rotor, a housing including bearing means for rotatably supporting and housing the shaft together with the rotor and the commutator mounted thereon, one end of the shaft projecting externally of the housing, a magnet disposed within the housing in opposing relationship with the peripheral surface or end face of the rotor, electrically conductive brushes located within the housing for sliding contact with the exposed portion of the commutator, and a thrust bearing plate mounted on the housing in bearing engagement with the opposite end of the shaft. The thrust bearing plate facilitates close control over the mounting position of the shaft, thereby stabilizing the positional relationship between the various parts.
