Description

3 eo

joints of insulating tape coincide with the places of bends of the workpiece.

Fig. 1 shows a rotor, a general view; Fig. 2 shows a winding blank wound on a template; Fig. 3 and 5 show the sequence of the bending of the blank} in Fig. 6 shows the surface of the rotor winding; Fig. 7 shows the layout of the leads on the workpiece;

Rotor 1, coils 2 windings are made of conductors 3. Outlet ends k of coils 2 are in this case brought to one side of rotor 1,

For the manufacture of the rotor, the wire (FIG. 2) is wound on the template 5t to receive the workpiece 6. The output ends (FIG. 1.6) can be arranged as shown in FIG. 7, Any means, for example, threads, can be used to fix the workpiece 6. tape and t, d. However, the best method of fixation is to impregnate the entire surface of the workpiece 6 with an adhesive. This provides for the elimination of overlaps by a row of lying conductors 3 of the blank 6 after removing the blank 6 from the template 5.

After removing the blank from the template

molding is performed, and the conductors in the active part expand at a predetermined angle oL to the plane, passing through the axis of rotation of the rotor.

The leads are formed by successive bending of the plane of the blank 6 at an angle (90-ci) to the axis of the conductors.

The number of such kinks is 2p, and the kink lines are evenly spaced around the circumference. As a result, the triangular windings of the winding are uniformly distributed around the circumference,

To insulate the turns, the preform 6 is wrapped with an insulating tape 7 (FIG. 3), the turns of the insulating tape 7 are arranged at an angle () to the axis of the conductors, and the joints of the insulating tape 7 are aligned with the kinks of the preform 6,

Execution on the specified method of winding with a triangular shape of a coil

eliminates the need to wind the workpiece on a triangular pattern, and therefore the deformation of the wire and; difficulties with the docking of the ends of the complicated workpiece.

Fixing the entire surface of the workpiece before removing it from the template ensures that the wires are arranged in a single layer without overlaps. All this improves the quality of manufactured electrical machines,
