Description

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

The purpose of the invention is to simplify the design and manufacture, as well as reducing the consumption of insulating materials.

The drawing shows a diagram of the winding.

The winding contains eighteen coils and is made single-layer in thirty-six grooves. In one branch, the phases are connected according to the coil, the sides of which are located in the grooves 30 and 9; 34.35 and 13.14, and in the other branch - 12 and 27; 16.17 and 31.32.

The end of the coil, the sides of which are located in the grooves 30 and 9 and the beginning in the grooves 12 and 27 are connected together and form a clamp of phase C1 for the pole P, = 1.

The beginning of the coils, the sides of which are located in the grooves 34, 35 and 13.14, and the end - in the grooves 16, 17 and 31.32 are connected to the additional terminals 0.1 and 02 for the pole P _a = 6. The phases C2 and SZ, the location of the coils of which alternates with an interval of twelve grooves.

The lower rad arrow in the drawing shows the direction of the currents when the winding is fed through the terminals C1, C2, C3 with a three-phase current, it can be seen that the field of these currents has the number of pole pairs P ₅ = 1. The upper row of arrows shows the direction of the currents when feeding the winding through the terminals 01 and 02 by a single-phase current, whence it can be seen that the field of these currents has P _g = 6.

The proposed winding is simpler to manufacture, as it is single-layer and contains 1.3 times less number of coils.

In addition, less insulation material is required to lay the winding due to the lack of insulation between the layers.

The invention relates to co-windings: electric mawain and can be used, for example, in single-machine frequency and number phase converters. The purpose of the invention is to simplify the design and manufacture, as well as to reduce the consumption of insulating materials. The drawing shows a winding circuit. The winding contains eighteen coils and is made single-layer in thirty-six grooves. In one branch of the phase included according to the coil, the sides of which are located in the slots 30 and 9; 34.35 and 13j14, and in the other branch - 12 and 27; 16,17 and 31,32, the cores, the sides of which are located in the slots 30 and 9 and the beginning in the slots 12 and 27 are joined together and form the clip of the C1 phase for, for instance, P 1. The beginning of the coils, the sides of which are located in the slots 34, 35 and 13.14, and the end in the slots 16, 17 and 31.32 are connected to the additional terminals 0.1 and 02 for polarity P, j 6. Phase C2 and NW, the arrangement of the coils of which alternates with an interval of twelve slots. The lower happy arrows in the drawing shows the direction of the currents when the winding is fed through the terminals C1, C2, and NW by a three-phase current, hence, the field of these currents has the number of pairs of poles P 1. The upper row of arrows shows the direction of the currents when the winding is powered through the pins 01 and 02 with a single-phase current , whence it is clear that the field of these currents has P 6, 52. The proposed winding is simpler to manufacture, since it is made single-layer and contains 1.3 times fewer coils. In addition, less insulation materials are required for winding laying due to the lack of insulation pads between the layers. The invention of the three-phase single-phase coil with pole 6, made in thirty-six grooves with numbers from 1 to 36, containing coils j connected in phases into two parallel branches, the beginnings of which form three-phase clamps for polarity P, and the end connected to two additional terminals for polarity, characterized in that, in order to simplify the design and manufacture, to reduce the consumption of insulating materials, the winding contains eighteen coils, in one phase branch are included according to the coil, the sides of which s are located in the grooves 30 and 9; 34,35 and 13,14, and in the other branch of this phase are included according to the coil, the sides of which are located in the slots 12 and 27 | 16,17 and 31,32, the end of the coil, the sides of which are located in the slots 30 and 9, and the beginning of the coil, the sides of which are located in the slots 12 and 27, are joined together to form a phase clamp, and the beginnings of the coils, the sides of which are located in the slots 16 , 17 and 31,32, are connected to the aforementioned additional points, the arrangement of the coils of the other phases alternating with an interval of twelve slots.
