ELECTRICAL MACHINE AND METHOD OF ITS MANUFACTURE Russian patent published in 1997 - IPC

FIELD: electrical engineering, applicable in manufacture of DC and AC electrical machines with a salient-pole stator, for instance, single-phase induction motors with shaded poles. SUBSTANCE: in electrical machine, using a stator with external and internal magnetic, circuits, pole coils, rotor and end shields, the latters are furnished with winding holders separating the coils from the poles. The coils are wound on the winding holders and function as braces. At assembly of such an electrical machine the rotor is introduced in the opening of the internal magnetic circuit of the stator, end shields are installed in the latter, and pole coils are wound on its winding holders bracing the members in a single assembly. In conclusion the external magnetic circuit is installed on the internal magnetic circuit of the stator on conjugated surfaces. EFFECT: enhanced adaptability to manufacture due to reduction of the number of fastening and insulating members, enhanced maintainability of the given machine due to possibility of rewinding of coils without disturbance of initial assembly of the rotor, end shields and stator internal magnetic circuit. 2 cl, 2 dwg
