FIELD: electricity. SUBSTANCE: combined winding of the induction machine with number of pole pairs 2p=4 and number of slots z=36 for number of parallel branches a=1 or 2 is made with pitch y=1-10 and contains 12 coils. Number of turns m"з" of odd coils and number of turns m"тр" of even coils comply with ratio EFFECT: increased specific power, decreased materials consumption, noise level and vibrations of the machine. 2 dwg
The invention relates to the electrical industry and allows to manufacture energy efficient electric machine, in particular high-torque low noise induction motor with enhanced performance characteristics. It is known that the shape of the curve of the magnetic field winding in the working gap of the classical (standard) electrical machines is "rough", step other than the sine wave. This leads to the modulation of MDS and the reduction of traction force of the rotor of the machine, undesirable acoustic noise and vibrations /1/, which is a known fault. Therefore, manufacturers tend specified curve closer to the sine wave in different ways /2, 3/. A well-known principle of forming the windings of energy efficient electrical machines with so-called six-phase combined windings (EN 109934 U1, publ. 27.10.2011, and EN 113090 U1, publ. 27.01.2012). These include commercially available high-torque induction motors series ADEM (design, http://www.uralelectro.ru/), combined stator winding which is selected as a prototype of the proposed technical solution. This winding can effectively suppress the higher odd harmonics MDS and consists of spatially combined composition of two three-phase interdependent parts (windings), collected in one star, the other third is Golnik, when the ratio of the numbers of turns of the triangle and the star is equal to Unknown scheme combined combined winding of an electric machine with a step y=1-10, the number of pairs of poles 2P=4, the number of parallel branches, a=1 or a=2 and the number of grooves z=36, in which a two grooves, the number of turns in the two times less than the number of turns in a single layer slots. The task, which directed the claimed solution, is the technical realization was not previously used in electrical engineering combined combined winding in the machine in increments of y=1-10, the number of pairs of poles 2P=4, the number of parallel branches, a=1 or a is=2 and the number of grooves z=36 order to obtain a technical result in the increase of its specific power, reduce material consumption, noise and vibration. This technical result is achieved by the combined winding induction machines with a number of pairs of poles 2P=4, the number of grooves z=36 for the number of parallel branches and=1 or 2 made in increments of y=1-10, contains 12 rolls, while the number of m3the odd turns of coils and the number of mTrturns the even-numbered coils satisfies the relation The winding scheme in the standard notation for a=2 is shown in Fig.1. The winding scheme in the standard notation for a=1 is shown in Fig.2. The novelty of the claimed technical solution due to the fact that the scheme of the combined winding of an electric machine with a step y=1-10, the number of pairs of poles 2P=4, the number of parallel branches and=1 or 2, and the number of grooves z=36 includes pole coils, which consist of two equal to the number of partitions of separate groups, while the even-numbered group is connected in star, odd - in a triangle or, on the contrary, even in the triangle, odd - star, the findings of the same phase star and triangle are interconnected and form a point of connection of the phases according to clarifying the nature of the claimed technical solution Fig.1-2. Unlike analogues and proto the IPA in these windings in the two grooves, the number of turns in half than the number of turns in a single layer slots. According to scientific-technical and patent literature not known to the authors declare the set of features aimed at achieving the objectives set for electric machines with combined combined winding increments y=1-10, the number of pairs of poles 2P=4, the number of parallel branches and=1 or 2 and the number of grooves z=36, and this decision does not follow clearly from the prior art. The proposed solution is industrially applicable. Sources of information 1. Design of electrical machines. Edited by I. P. Kopylov. Meters, Energy, 1980. 2. A. C. Barkov, N. A. Barkov.
