FIELD: electricity. ^ SUBSTANCE: invention relates to the field of electric engineering, in particular to single-phased electric generators with electromagnetic excitation executed via contact rings directly from source of DC voltage and may be used in autonomous systems of electric equipment, in automatics and household appliances, on aviation and motor transport, as wind power generators, high-frequency electric generators, synchronous converters of single-phase alternating current frequency, and also in rectification of alternating EMF with the help of uncontrolled and controlled semiconductor valves - as DC generators, contactless exciters of synchronous generators of mobile mini-power stations and low-capacity power stations. Proposed single-phase electric generator comprises stator, anchor core of which is assembled from insulated sheets of electrotechnical steel with high magnetic permeability and has explicit poles with coil single-phase winding of anchor, each coil of which is arranged on according explicit pole of anchor, and rotor comprising inductor with even and odd cores with identical number of explicit poles on each core, even and odd cores of inductor are arranged in the form of packets assembled from insulated sheets of electrotechnical steel with high magnetic permeability, number of inductor cores is at least two, even inductor cores are displaced relative to odd ones in tangential direction by half of pole division of inductor core, inductor cores are placed onto magnetic conductor of inductor, between cores of inductor there are ring-like coils of inductor excitation winding arranged as supplied by DC (rectified) current via brushes and contact rings. At the same time certain ratios must be maintained between number of explicit poles of anchor, number of explicit poles on each inductor core, width of pole arc of explicit anchor poles and width of pole arc of explicit poles of each inductor core. ^ EFFECT: provides for high power and operational indices of single-phased electric generator. ^ 12 cl, 6 dwg |
