Description

  .- .:

The invention relates to process equipment for laying windings in the grooves of the magnetic circuits of electrical machines. And can be used in the electrical industry.

A device is known for sealing windings in the grooves of magnetic circuits of electric machines containing a mandrel made of an electrically conductive non-magnetic material with rigid conductors embedded in it - bars and a source of electrical energy I.

However, the known device is used ONLY to seal the windings in the grooves of the magnetic cores, and the laying of the windings into the grooves is done by another device, as a result of which the performance of the laying of the winding is reduced.

It is also known a device for laying windings into the grooves of the magnetic circuits of electrical machines, comprising a mandrel with grooves for measuring coil groups and a source of electrical energy.

However, the laying of the windings in this device is performed by separate coil groups, which reduces the performance of the device.

The purpose of the invention is to increase productivity by simultaneously laying down all the coil winding groups.

For this, the mandrel is made in the form of prisms with grooves fixed on a flexible base of an IZ dielectric, and on the base, on the side opposite to the arrangement of the prisms, a flexible tape of electrically conductive material is attached, at the ends of which there is a strap.

FIG. 1 shows a device for laying windings into the slots of the core, general view; in fig. 2 - the device is in working position; in fig. 3 - device for laying the coil groups in the stator slots in the unfolded form - the initial position; in fig. 4 - section A-A of FIG. 3; FIG. 5 shows a device for laying the coil groups into the stator slots in the operating position.

The device for laying the windings into the grooves of the magnetic circuit of electric machines contains a mandrel consisting of a flexible base 1 made of a dielectric material on which prisms 2 made of a dielectric with slots for placing coils of coils 3 are placed in them. Prism 2 has wide edges fixed on a flexible base 1. On a flexible base, on the side opposite to the location of the prism, a flexible tape 4 of electrically conductive material is attached, at one end of which there is a latch 5, and on one ohm fixed ear 6 for its entry. Lead the ends of the turns of the conductors of the roller group 3 is connected to the generator 7 pulsed current. For simultaneous pouring of all the coil winding groups into the stator slots of the electric prism 2 masking machine, narrow edges are fixed on a flexible base with the possibility of free movement. The device for laying the wraps in the grooves of the magnetic circuit of the electric motor operates as follows ... In the initial position of the device rim is in the unfolded position, while the prisms 2, located on the gibkoni base 1 and the electrically conductive tape 4, are located with a clearance of each other relative to each other (Fig. 1) or touching at the upper points (Fig. 3). Then all the coil winding groups are inserted into the slots of the pris 2 (Fig. 1, 3) n and connected to the source 7 of the pulsed current. After this, the cage with flexible base 1, prisms 2 and electrically conductive tape 4 is folded into a ring and the latches snap into place. A 5 snaps onto the cane: (Figs. 2, 5). Into the device with all the grooves of the coils 11Mi Tpj niMiMH inserted into the 4Ws of the conductor core or stator, while combining its grooves with the slots of prisms 2, after which the source of pulsed energy is switched on. Under the action of a pulsed current between the coil groups and the magnetic circuit of the electric machine, electromagnetically generated forces arise, with which all coil groups are laid into the grooves simultaneously. In turn, the tape 4 of electrically conductive material forms a short-circuited coil in which a current is induced during the pulse supply of the winding, as a result of which an additional force is created which pushes the coils of the coil groups 3 out of the slots of the prisms 2 into the slots of the magnetic circuit. The device allows to increase productivity by simultaneously laying all the coil winding groups by making the mandrel in the form of prisms with grooves attached to a flexible base. The invention The device for laying windings into the grooves of the magnetic circuits of electrical machines, comprising a mandrel with grooves for accommodating coil groups and a source of electrical energy that is different in that, in order to increase productivity by simultaneously laying all the winding groups of windings, the mandrel is made in the form of grooved prisms, mounted on a flexible base of the dielectric, and on the base, on the side opposite to the arrangement of the prisms, a flexible tape of electrically conductive material is attached, at the ends of which installed latches.
