SU425280A1 - LINEAR INDUCTOR OF THE INDUCTION MACHINE - Google Patents

Description

This invention relates to induction machines with an open magnetic circuit. Known flat linear and. Conductors with open magnigoprovod - and located in the grooves of the last corrected wave winding. However, in such linear inductors, a large number of winding conductors are used, which curl the ends of the magnetic circuit to correct the latter. The purpose of the invention is to reduce the consumption of the winding wire, and in the particular case of other materials, as well as to reduce the length of the magnetic conduit. For this, a troupe of conductors of the same phase, located in the extreme ends of the inductor and forming, and one zerous, is divided into two parts, one of which is placed at the beginning of the inductor, and the other at its end. In the case that the linear inductor is made with an odd number of slots per pole and phase q, at least three, these two winding parts can occupy the same number of slots equal to d-1 at the beginning and end of the inductor. In FIG. 1 shows a diagram of a three-phase wave winding with the number of slots per pole and phase q 2 and its placement in the names of a known inductor; “And FIG. 2 shows a similar circuit for winding a linear inductor made in accordance with the present invention; in fig. 3 is a diagram of the wave winding c and its placement in the slots of a known inductor; in fig. 4 is similar to the winding circuit of a linear inductor made in accordance with the present invention. In the known inductors shown in FIG. 1 and FIG. 3, at the beginning of the inductor there are q names, in which the conductors of the phase AX are located, and at the end - q slots, in which the conductors of the SU phase are located. In the proposed inductors, the group of conductors of the phase CY, located at the end of the inductor, is divided into two parts, of which one part is also located at the end of the inductor - in its last groove, and the other part is transferred to the beginning of the inductor and occupies its first groove. Separating the phase zone into two parts allows reducing the number of wiring right of conductors enveloping the ends of the magnetic conductor and reducing the consumption of the winding wire. Thus, with the number of grooves per pole and phase q 2. In a known inductor (see FIG. 1), six conductors bend around each end of the magnetic circuit, and four conductors in the proposed (see FIG. 2).

With q 3, in the known inductor (see Fig. 3), the end of the magnetic circuit bends around nine conductors, and in the proposed (see Fig. 4) seven.

With an odd number of grooves per pole and phase, but not less than three, the invention provides that each part of the divided phase winding zone occupies an equal number of grooves equal to d-1 at the beginning and end of the inductor

If in a known inductor (see Fig. 3) the conductors of the SU phase, which are laid at the end of the inductor, fix three slots, then in the proposed conductor of the indicated phase zone are placed in two slots. In this case, the total number of winding conductors is reduced, the extreme lengths of the magnito are: the wires are replaced with the teeth of a normal width, and the length of the magnetic circuit is reduced by the value of the width of one slot.
