<p>The invention relates to a winding for three-phase electrical machines of alternating current, with commutative poles in the 4:6 ratio, made in two embodiments: in one layer and in two layers. According to the invention, the winding consists of 24 coils with the same number of spires and opening of 9 notches, in the variant of making the winding in one layer on each phase there being placed 8 serially connected coils, for low speed, corresponding to 6 poles and 2 groups of 4 parallely connected coils for high speed corresponding to 4 poles, and 48 coils, equal as spire number and opening of 8, 9 or 10 notches, in the embodiment in two layers, on each phase there being placed 16 coils, all serially connected, for low speed, and 8 parallely connected coils, on each of the two paths of current, for high speed.</p> |
