Abstract
An electric machine comprising a stator and a rotor. The stator consists of two sections made of a mouldable plastic material wherein at least the means providing the magnetic flux is formed integrally with the stator sections. The assembly further includes means securing the stator sections in position circumscribing the rotor.
Claims4
An electric machine consisting of a stator and a rotor, said stator comprising at least two sections made of a mouldedplastic material, magnetic flux providing means in the form of laminations formed integrally in each section, said laminations running axially and having inwardly directed terminal edge portions adjacent the inner arcuate surface portions and forming the stator poles, the central part of the laminations forming the stator yoke, each section having circumferentially spaced inner peripheral surface portions of arcuate cross section, said inner peripheral surface portions disposed on the circumference of a circular trace defining the rotor cavity, at least one of said sections having a longitudinally extending interior channel between said inner surface portions forming mounting means for windings, each section having axially spaced pocket sections defining an annular seat for bearings within which the rotor shaft is journalled and clamping means securing the sections together.
