SALIENT-POLE COMMUTATOR MACHINE Russian patent published in 2011 - IPC H02K23/02 H02K23/40 H02K23/26 

FIELD: electricity.

SUBSTANCE: power supply to proposed electric machines at their operation in mode of motors can be performed not only from stationary electric AC mains of commercial frequency with its further conversion to DC, but also from movable and portable independent direct current sources (minielectric power stations, storage batteries and galvanic power elements). Salient-pole commutator machine includes housing made from soft magnetic material, salient poles of inductor with coil excitation winding of inductor, armature with salient poles, commutator, mechanism of brush-and-contact assembly with brushes, closed subsequent (wave) coil armature winding consisting of coils each of which is located on the appropriate salient pole of armature, and beginnings and ends of coils are connected to each other in certain way and connected to the appropriate commutator bars of commutator, thus forming closed electric circuit with two parallel branches. At that, it is necessary to follow certain ratios between the number of inductor poles and the number of armature poles, as well as to make their pole arc of certain width, and commutator bars and brushes of certain width and certain number.

EFFECT: high energy properties of salient-pole commutator machine with high commutation, and smooth control of output parametres at simultaneous simplicity and high reliability of the design of electric machine.
