Problems solved by technology
The disadvantage of this traditional slotted generator is that since both the stator core and the rotor poles must be slotted, the silicon steel sheet used cannot be brittle cold-rolled oriented silicon steel sheet with high magnetic permeability, but can only be used. Low-silicon silicon steel sheets lead to low power generation efficiency: the power generation efficiency of ordinary generators is 75%-80%, and the efficiency of automotive silicon rectifier generators is 50%.
In order to improve the efficiency of the generator, the applicant successively released slotless generators with patent numbers 97126126.1, 97126127.X, and 200410023516.4 in 1997 and 2004. After many tests, the power generation efficiency of these slotless generators Although it has been greatly improved compared with the traditional slotted generator, it is still not ideal, and there is still room for improvement in power generation efficiency

A phase splitting magnetic circuit generator includes stator and rotor, said rotor including even number magnetic poles. It features stator core number being twice of even number pole, these stator core divided into two sets, silicon steel sheet made in swallow-tailed iron core seat rigid coupling in internal surface of stator each iron core column crossing distributed along circumference surface, stator coil divided into two-phase respectively wound each iron core column of two sets stator core, winding direction according to clockwise then counter-clockwise circulation sequence. The generating efficiency of Said phase splitting magnetic circuit generator is greater than 90 per cent, if used in automobile current generator the generating efficiency is 86 per cent.
Description
technical field [0001] The invention relates to a generator, more specifically a phase-splitting magnetic circuit generator. Background technique [0002] The traditional slotted generator mainly includes two parts: the stator and the rotor. The stator core is made of laminated circular silicon steel sheets insulated from each other. Several grooves must be punched on each lamination. Stator coils are embedded, and the rotor includes a rotating shaft. The rotating shaft is equipped with rotor poles punched and laminated with silicon steel sheets or steel plates. Exciting coils are wound on the rotor poles. The disadvantage of this traditional slotted generator is that since both the stator core and the rotor poles must be slotted, the silicon steel sheet used cannot be brittle cold-rolled oriented silicon steel sheet with high magnetic permeability, but can only be used. Low-silicon silicon steel sheets lead to low power generation efficiency: the power generation efficienc...
