METHOD FOR MANUFACTURE OF ELECTRIC MACHINE ROTOR WINDINGS MANUFACTURE AS WELL AS ELECTRIC MACHINE WITH ROTOR WINDING MANUFACTURED BY THIS METHOD Russian patent published in 2013 - IPC H02K23/30 H02K23/38 H02K15/09 

FIELD: electrical engineering.

SUBSTANCE: one manufactures rotor winding with at least four poles (P) of the stator (11) excitation and a collector rotor (13) having grooves (N) and pole cogs (Z) (the number whereof is other than that of excitation poles), coils (S) wound onto individual pole cogs and the same number of collector plates (L) being at least twice in excess of that of the pole cogs. Each coil beginning with the first one (S1) is wound onto the pole cog for which angular deviation (Wf) from the angle determined by the polar pitch (Pt) is the minimum. For simplification of the winding wire (17) laying within the zone of its connection to the collector plates it is stipulated that, at least for the coils (S) of the winding line (B) which is the last to be wound (and preferably - for all the winding coils), the winding wire (17) being placed in contact with the collector plate (L) between two coils (S) is led to the plate (L) on one side and led from the plate - on the other side. Positioned between the grooves (N) wherefrom the winding wire (17) is led to the plate (L) and the groove whereto (N) the wire is led from the plate is at least one pole cog (Z) but no more than to pole cogs (Z).

EFFECT: improvement of reliability by way of improvement of the coils contact to the collector plates and of the conditions of laying the wire in proximity to such plates commutator lugs as well as prevention of loops springback from the wire.
