SU394892A1 - LINEAR INDUCTOR OF THE INDUCTION MACHINE - Google Patents

Description

one

Linear inductors of induction machines are known, containing an open magnetic circuit and a winding with at least two phases consisting of working coils, the sides of which are located in two different slots of the magnetic conductor, and coils used to suppress the pulsating field component, in which the groove of the magnetic circuit, and the other - outside the active zone.

To reduce the consumption of the magnet wire and electrical steel, as well as reduce the length of the inductor, the proposed inductor is made with a number of teeth equal to the product of the number of pole pairs (2p) by the number of grooves in the pole and phase () and the number of phases (t) and the number of grooves equal to the specified product, reduced by one (2pqni-1).

FIG. 1-4, various variants of the distribution of the phase zones of the currents across the slots of the linear inductor are presented.

The frontal parts (pas to one edge of the inductor) are shown by arcs. Winding (see Fig. 1 and 2) have the number of grooves per pole and phase q. These windings can be performed on the same principle with 2, 3, 4,. . The windings (see Figs. 3 and 4) have, but can also be performed with (, 6...... All windings are corrected.

Inductors (see Fig. 2 and 4) are made with the number of teeth equal to the product of the number of pairs of poles and the number of slots PA pole n phase and the number of phases (2pqm) and the number of slots smaller than the number of teeth per unit (2pqm-1) . In this case, the left semi-teeth of a known inductor are replaced with whole teeth, the right semi-teeth eliminate and the coils, which are wrapped around only the right semi-teeth, are guessed. The inductors in FIG. 2 and 4 contain one coil (YB) less than the inductors in FIG. 1 and 3.

With a decrease in the number of coils, the magnetic circuit and the inductor as a whole are shortened. The length of the toothed side frame of the inductor in the conventional version (see Fig. 1) is equal to / 1 2t + 2 & P. where t is the pole division, bn is the slot width. The length of the toothed side frame of the proposed inductor (see FIG. 2) is equal to / 2 2m + lp.

Thus, the length of the described inductor is less than the length of the known inductor by the width of the groove b.

Subject invention

The inductor of the induction machine contains an open circuit and a winding with at least two phases consisting of working coils, the sides of which are located in two different slots of the magnetic conductor, and coils serving to suppress the pulsating field component, in which the single side is placed in the groove the magnetic conductor and the other outside the active zone, characterized in that, in order to reduce the consumption of the magnet wire and electrical steel, as well as to reduce

the length of the inductor, the latter is made with the number of teeth equal to the product, the number of pole pairs (2p) and the number of grooves per pole and phase q and pas number of phases (t), and with the number of grooves equal to the specified output reduced by one (2pqm- one).
