Abstract

The invention relates to windings of electric brushless AC machines with two opposite-pole magnetic fields combined in a common magnetic circuit. The purpose of the invention is to expand the area of application of the winding by obtaining pi / p2 4/2 polarity with single-phase for PI polarity and four-phase for polarized p2 clamps. The winding is made of eight equally spaced rolls and is connected in parallel branches for polarity p with additional clamps for polarity p2 from the midpoints of the branches. Coils are included in four branches with numbers 1 and 7 in the first, 2 and 8 in the second, 3 and 5 in the third, 4 and 6 in the fourth. Additional clamps are made from the midpoints of all four branches, and the groove pitch of the coils is T2-1, where pole division is for polarity p2. Even coils are included in the branches x is relatively odd. 6 Il.

The invention relates to windings of electric machines of alternating current with two opposite-pole fields in a common magnetic conductor.

The purpose of the invention is to expand the field of application of the winding by obtaining a pole with single-phase for polarity p and four-phase for polarity of PZ terminals.

FIG. 2,, 6 EMF vectors are assigned numbers of coils, whence it is seen that the field with a voltage of 5 p does not induce EMF at terminals A, B, C, D (Fig. 2 and 5), and the field with polarity PZ does not induce EMF clamps 01-02 (Fig. 3 and b). The winding factors are: for the winding of FIG. 1 -, 707,
