STATOR OF ROTATING ELECTRIC MACHINE WITH CONSTANT EXCITATION Russian patent published in 2014 - IPC H02K1/16 H02K3/28 

FIELD: electricity.

SUBSTANCE: in the middle of the first coil group (10a) there is a middle tooth (8a), which has the first MB width of the middle tooth. A stator (5) has the second group (10b) of coils. The first and second groups of coils are placed in the circumferential direction (U), directly in sequence one after another. Between the first and second groups of coils there is the first edge tooth (9), which has the first RB width of the edge tooth. In essence the first RB width of the edge tooth is equal to RB=a·ZB, and the first MB width of the middle tooth is equal to MB=(2-a)·ZB. The coefficient a is bigger than 0 and less than 1.

EFFECT: reducing rest and swivel moments occurring in the rotating electric machine (1) with constant excitation.
