FIELD: electricity.
SUBSTANCE: single-phase contact-free electromagnetic generator includes stator with anchor core composed of insulated electrical steel sheets of high magnetic inductivity and features distinct poles with single-phase anchor coil winding where each coil is positioned at respective distinct anchor pole, and winding-free ferromagnetic rotor including inducer with even and odd cores with the same number of distinct poles in each core. Odd and even inducer cores are made in the form of banks assembled of insulated electric steel sheets of high magnetic inductivity, inducer features at least two cores, even inducer cores are shifted against odd cores in tangential direction for a pole half-pitch of inducer core, inducer cores are set on respective magnetic conductors of inducer, annular layers of segmental permanent magnets magnetised in the one direction are positioned between magnetic conductors of inducer. Certain ratio should be maintained between number of distinct anchor poles and number of distinct poles in each inducer core, and between pole arc width of distinct anchor poles and pole arc width of distinct poles of each inducer core.
EFFECT: high reliability and manufacturability of single-phase electromagnetic generator design, good energy and operational characteristics.
