FIG. 1 shows the position of the elements of the magnetic circuit before assembly; in fig. 2 - napressovka first sheet on the sleeve; in fig. 3 pressed package on the sleeve; on, 5 fig. 4 - package, pressed on the shaft.

The method of assembly of the rotor magnetic circuit of an electric machine is as follows. 20

At the first position of the stamp in electrical steel steel, the holes for the rotor hub and grooves are pre-cut, along which the plate is oriented along the

matrix guides (not shown) · during assembly.

Sheet 1 of the rotor or anchor simultaneously ^? Together with the cutting of the external contour, the punch 2 is pressed onto the sleeve 3, which is located on the technological mandrel 4, which is stationary in the process of cutting the sheets, and is installed under the pressed sheet (Fig. 1). Each subsequent punch-pressed sheet pushes along the sleeve the previous sheet by the sheet thickness (Fig. 1-3) and takes its place. After the required number of sheets are mounted on the sleeve in the above sequence, the working part of which is simultaneously the metering unit, since it is equal to the height of the assembled package of magnetic rotor or armature, when the last sheet is pressed, the package is pressed. The pressurized package is removed with a sleeve from the technological mandrel, is poured with aluminum, pressed onto the shaft and mechanically processed (Fig. 4).
