The winding is made in devosta grooves, consists of thirty eight coil groups. Coils in coil groups are distributed in accordance with the numerical series of 3, 3, 3, 4, 2, 3, 3, 2, 1, 2, 1, 3, 1, 1, 3, 2, 3, 3, 2, 3 , 3, 3, 4, 2, 3, 3, 2, 1, 2, 1, 3, 1, 1, 3, 2, 3, 3, 2. Coils are included in phases, divided into semi-phases. The conclusions are made from the beginnings and ends of the phases and junctions of the semi-phases. It is indicated which coil groups are included in each semi-phase. This embodiment of the winding reduces the number of leads, which simplifies the design. 1 il. you about tc to 4

Description

The invention relates to poleasable windings and can be used in multi-speed AC motors.

The purpose of the invention is to simplify the construction.

The drawing shows a winding scheme with the ratio of the numbers of poles 2Pi: 2Pz 10:12, the coils of which are laid in 90 slots with numbers from 1 to 90 in steps of 8. 8. The winding is made three-phase, two-layer, symmetric and contains 38 coil groups with numbers from 91 to 128.

The three-phase pole-switch, and the winding with the ratio of the numbers of pairs of poles 2Я 10:12 in the number of stator slots Z 90, is made of uniformly distributed coil groups consisting of identical coils and included in phases, divided into half-phases, with conclusions from the beginning and end of the phases and The connection points of the 5 semi-phases, characterized in that, in order to simplify the construction, it contains 38 coil groups with numbers from 91 to 128 with the number of coils in each group, determined in accordance with the numerical
