METHOD FOR MANUFACTURING OF ELECTRIC MACHINE ROTOR WINDING Russian patent published in 2009 - IPC H02K23/30 H02K23/26 H02K15/09 

FIELD: electricity.

SUBSTANCE: invention is related to the field of electric engineering and concerns technology for manufacturing of electric machine rotor winding. Method is suggested for manufacturing of electric machine (10) rotor winding, comprising at least four excitation poles (P) installed in stator (11), collector rotor (13), having grooves arranged along circumference and pole teeth (Z), number of which differs from number of excitation poles, sections (S) of winding and the same number of collector plates (L), number of which is at least twice more than number of pole teeth (Z). As sections (S) are wound onto pole teeth by winding wire in continuous mode, after fixation of winding wire (17) on initial plate (La) on the first pole - tooth (Z1) the first section (S1) of winding is wound with selected angle shift (φ₀) relative to initial plate (La), then winding wire (17) with specified pitch (Y) along collector is fixed on another collector plate (L), which is a final plate (Le) for wound section, then serially from each collector plate (L) winding section (S) is wound onto pole tooth (Z) with lowest deviation (Wf) of selected angle shift (φ₀) from electric angle identified by pole division of stator, afterwards winding wire (17) is entered in contact with another plate (Le), which is spaced by specified pitch (Y) along collector until all winding sections (S) are wound on pole teeth (Z).

EFFECT: provision of low pulsations of rotation torque and long service life due to optimal commutation of winding sections (S).
