FIELD: electricity.
SUBSTANCE: attitude of rotor winding of the offered synchronous DC machine is synchronised with instant magnetic fluxes of phase windings. Thus rotor is synchronised with rotating field so that at reference-starting point rotor positions relative to phase winding axes to provide the greatest total performance of machine. If required (e.g. for start-up operations) rotor can be fixed in this position with adjusting screw. And stator of machine is made of nonmagnetic material.
EFFECT: maximal time average transformer voltage in rotor winding and maximum voltage in brushes of this electric machine when operating as generator.
