STATOR OF ROTARY ELECTRIC MACHINE AND ELECTRIC MACHINE WITH THIS STATOR Russian patent published in 2012 - IPC H02K1/16 

FIELD: electricity.

SUBSTANCE: in accordance with this invention an improved stator (28) is proposed for rotary electric machines, with single-layer stator windings, comprising multiple previously formed coils (22) with identical angle pitch. The stator (28) comprises the first cylindrical surface, in which there are multiple slots (30) of windings displaced along the circumference, into which arms (24) of the previously formed coils (22) are inserted as arranged along the axis. Each of two arms (24) of the winding in each coil (22) are inserted into an appropriate slot (30) of the winding, besides, two slots (30) of the winding, where a coil (22) is inserted, form a pair of the winding slots. Improvement consists in the fact that slots (30) of the winding in each pair of the winding slots enter the stator (28) mainly in parallel directions. It means that arms (24) of the winding arranged along axis in every previously formed coil (22) may also be mainly parallel and do not require arrangement at the angle to each other. This makes it possible to simplify making the stator (28), since each previously formed coil (22) may be easily and simply inserted into a pair of parallel slots for the winding.

EFFECT: reduced time for winding of a stator in a rotary electric machine with simultaneous reduction of possible damage in the process of winding of previously formed coils.
