Description

The invention relates to the windings of electric machines of alternating current and can be used, for example, in single-machine frequency and phase converters.

The purpose of the invention is to improve the use of active materials.

The drawing shows a winding scheme for 2 and 18 poles, made in 48 slots.

The winding contains 24 coil groups with numbers from 1 to 24,

When the alternation of the numbers of coils in the coil groups correspond to 15 poles of P, their zero points are in the range of –3,1,1,151.3,3,3,3,1,1,1,1,3,3,3,3,1,1 1,1,3,3,3.

in the first phase, the first three-phase star connected to the clamps C1-02 is connected in series to the coil groups 5, 7 according to and opposite to them - 16, 18.

two additional clamps for polarity P; and in each star of the phase the coil groups are connected in series, which differs from

20 by the fact that, in order to improve the use of active materials, the winding is made in the number of slots, a multiple of 48, from. 24 coil groups with order numbers from 1 to 24, numbers

Phases C2 and Sz are similarly executed and the numbers of their coil groups with respect to phase CI alternate with an interval of eight groups.

The upper row of arrows in the drawing shows the direction of the currents when the winding is supplied to the windings C1, C2, NW by three-phase current (for the point in time when the current in phase C1 has the maximum value), whence it is seen that 2P 2.

The bottom row of arrows shows the direction of the currents when the winding is powered through outputs 01 and 02 by single-phase current, whence it is seen that 2P 18.
