(57) Abstract: Use: commutator electric machine mainly AC power for household appliances. The inventive two-pole commutator electric machine includes an inductor, an anchor with an even number of teeth Z and a simple loop winding of 2Z sections and step 05Z-1, the collector 2Z plates and brushes, three lock-up manifold plate and the second side of each second section is placed in the same groove with the first side of the preceding section and the second end section connected to the end of the preceding section and start with the beginning of the subsequent. Technical result: increasing reliability, reducing radio interference. 1 Il. The invention relates to the field of collecting electrical machines, mainly AC machines for household appliances. Widespread use among household electric machines have a two-pole machine with an even number of teeth on the anchor, the number of winding sections, twice the number of teeth, and brush width, close to 1.5 collector divisions. The parity of the number of teeth allows the sections in pairs positioned parallel to each other (so-called H-winding), to enter although the second number of teeth, when the above width of the brushes is the absence of any damping of the residual EMF in section, up in the groove of the latter, which causes heavy wear of the brush-collector node and an increased level of interference. Splitting the section into pieces, placed in different slots, allows to compensate for the residual voltage in the extreme section of the groove, but the circuit of the winding and the manufacturing process complicated, increases the width of the zone switching, reduced utilization of active materials. The present invention allows, without complications of construction and reduction of energy data to eliminate the disadvantage of the prototype, i.e., to improve the switching, to reduce the level of interference and the rate of wear of the brush-collector node. In the proposed two-pole commutator electric machine containing the inductor with poles, anchor with an even number of teeth Z and a simple loop winding having 2Z sections with the same direction nmode and the step of winding the slots of 0.5 Z-1, the collector number plates 2Z and brush with wide, providing premikanje three collector plates, and the ordinal numbering of the sections are installed by first connecting to the manifold, the second side of each second section is placed in the same groove with the first side of the preceding sections and the end of the specified Vania illustrated in the drawing, where the scheme winding for an electric machine having a number of teeth Z 12 and twice as a large number of sections and collector plates. In the drawing, 1 section, 2 brushes, 3 collector plates, 4 slots, 5 zone switching. The arrows show the passage of currents in sections 1 when specified by the signs "+" and "-" polarity brushes 2. The first side sections shown in solid lines, the second hatched. The two lines crossed out of the side sections, the switched positive brush 2, one switched negative brush 2. As presented in the diagram position, when each of the brushes 2 perimice 3 collector plates, side switched all 4 sections 1 are located in 4 slots 4, and in each groove are one side of the section 1, start-up switching under one brush 2, and one side of the section 1, the final switching under a different brush 2, which provides damping the movement of the residual energy from section to section, making it easier switching. With respect to the brushes 2 slots with 4 interconnected switched sections 1 take positions that differ across the collector division, so the completion of switching all sections of these grooves are separated by time and the process of transfer of energy between computerweekly winding without crushing sections, therefore the utilization of active materials maximum. The proposed schema change winding does not change the basic characteristic of a simple loop winding connection of the ends of the sections 1 to two adjacent collector plates 3, so winding it is advisable to use the name "simple loop with alternating directions of winding steps along the slots". When performing continuous winding wire instead of changing the direction of connection of each of the second section changes the direction of its winding. Two-pole commutator electric machine containing the inductor with poles, anchor with an even number of teeth Z and a simple loop winding having 2Z sections with the same direction of winding and the winding step along the slots of 0.5 Z 1, collector number plates 2Z and brush with wide, providing premikanje three collector plates, and the ordinal numbering of the sections are installed by first connecting to the manifold, wherein the second side of each second section is placed in the same groove with the first side of the preceding section and the end of the specified second section connected to the end of the preceding section and start with the beginning of the subsequent sections.
