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

FIELD: electricity.

SUBSTANCE: salient-pole commutator electric motor includes housing, core of inductor with salient poles, which consists of isolated electrotechnical steel sheets with high magnetic permeability, 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. Inductor excitation winding is connected in series in relation to armature winding. 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 electric machine with high commutation, and smooth control of output parametres at simplicity and high reliability of the design.
