Winding of energy-efficient asynchronous motor

摘要

The utility model refers to the field of electrical engineering, namely to electric machines, stator designs of alternating current machines. The present invention can be used in any industry where an electric drive is used.;The technical result is the possibility of upgrading the existing fleet of standard asynchronous machines, in which the ratio of the phase angle of the same windings α₀= 30 electrical degrees and slot angle α_z= 27πp / z is not equal to an integer (α₀/ α_z≠ k, where k is any integer) with the improvement of manufacturability and with a reduction in the labor intensity of manufacturing and stowing the stator windings. An energy-efficient engine includes two interdependent combined windings, one of which is assembled into a "star" and the other to a "triangle". These windings are placed in the grooves so that the resulting vectors of induction of the magnetic fluxes of the pairs of poles of the same phases of the "star" and "triangle" form between each other in the working air gap the angle of phase shift of the same windings α₀= 30 e. degrees, and the number of turns of the "triangle" and "star" is equal to the ratio for cases when the ratio of the angle of shift α_z and the slot angle α_z not equal to an integer (α₀/ α_z≠ k, where k is any integer).
