    PCT No. PCT/RO81/00004 Sec. 371 Date Jul. 30, 1982 Sec. 102(e) Date Jul. 30, 1982 PCT Filed Aug. 4, 1981 PCT Pub. No. WO82/01965 PCT Pub. Date Jun. 10, 1982.The invention refers to a brake electrical asynchronous motor with short-circuited rotor and double drive, where its magnetic field simultaneously generates both the revolving torque on the rotor, and the electromagnetical force for deblocking the brake. The motor, according to the invention, is characterized by a constructive system with a normal stack of statoric sheets, elongated by a supplementary stack of statoric sheets, having the same cross-geometry as the normal stack of statoric sheets, with an excitation winding common to both, a normal stack of rotoric sheets with the cage rods elongated into the area from under the supplementary stack of statoric sheets, and separated by stacks of teeth between which are created slots with the same shape with those in the area of the normal stack of statoric sheets, but opened towards the inside and short-circuited through these openings by the short-circuiting ring, located in this area. When power supplied at the statoric winding, between the front surface of the stacks of teeth that separate the rotoric cage rods in the area from under the supplementary stack of statoric sheets, and the adjacent front surface of the brake deblocking movable armature an axial attraction electromagnetic zone appears, being generated by the summed action of the magnetic field created by the current flowing through the short-circuiting ring, and of the magnetic field created by the statoric excitation winding in the area of the supplementary stack of statoric sheets, force that nullifies the pressure between the friction faces given by the pressure spring and the braking torque, disappears.

    Layout 8. The axially displaceable brake release element contains a magnetic pipe 9, the active surface of which is located against the end surface of the P teeth 6. This element is mounted on the shaft 4 by means of a needle bearing 10, which allows axial movement . The rod 11 is mounted in the cavity of the shaft 4 and connected to an axially displaceable brake release element by means of a screw 12 passing through a hole in the shaft 4. The pressure spring 13, which provides the braking force, is located around the rod 11 and is operated at one end on the corresponding the shoulder in the shaft 4, and the other on the nut 14 for adjusting the pressing force

    The invention relates to electrical engineering, in particular to electric asynchronous motors with an integrated brake.
    The aim of the invention is to increase the pulling force during throttling.
    Figure 1 shows the electric motor, a longitudinal section, and Figure 2 is the same, the cross section in the rotor zone, located under the additional stator package.
    The engine (figure 1) contains the stator. Of the main 1 and an additional 2 packages. Both packages have the same grooves in which the excitation winding 3 is installed. On the motor shaft 4 there is a rotor package 5, which has cage rods elongated in the area under the additional stator package 2 and located in this area in the grooves between the packages of 6 teeth. The grooves have the same shape as in the area of the rotor package 5, but open inside (figure 2). The rods are closed short circuit ring 7, located under the package of 6 teeth. Between the package of 6 teeth and the package 5 of the rotor, there is an insulating gasket 8, the axially moving brake release element contains a magnetic seal
    friction discs. One of the fractional disks is mounted on the fan blades 15, and the other friction disk is mounted on the engine block. The element, not the friction disc, is fixed on the shaft 4 by means of a needle bearing 16, which provides axial movement. The fan 15 is fixed on the shaft by means of a splined hub 17. There is a nut 19 for adjusting the wear of the friction discs. Due to the arrangement of the magnetic conductor 9 of the axially displaceable element for switching off the brake against the P teeth 6 and the end surface of the ring 7, the tractive effort increases, which ensures the release of the engine. 3 hp f-ly, 2 ill.

    waters 9, the active surface of which is located against the end surface of the packages 6 teeth. The element is mounted on the shaft 4 by means of a needle bearing 10, which allows axial movement. A rod 11 is inserted through the central hole in the shaft 4, connected to an axially movable brake release element with a screw o, 12, which radially passes through the hole in the shaft 4, made oval, elongated along the shaft 4. Push 5 - spring 13, ensuring force braking, is located around the rod 1 1 and rests at one end on the corresponding shoulder of the central hole in the shaft 4, - and at the other end - on the shoulder of the adjusting nut 14.
    One of the friction discs is installed on the fan blades 15, and the other friction disc is mounted on the engine block. The bearing element, made in the form of a fan 15, on which the friction disk is mounted, is fixed to the shaft 4 by means of a needle bearing 16, which provides axial movement.
    Torque or braking torque is transmitted from shaft 4 to the fan.

    15 and, respectively, back with the aid of a splined hub 17 fixed to the fan 15 with screws 18.
    The axial movement of the rod 11 under the influence of the axial electromagnetic braking force acting on the axially displaceable braking element and the braking force from the pressure spring 13 is transmitted to the fan 15 by the nut 19 for adjusting the wear of the friction discs.
    The nut 14 for adjusting the force of pressing the disks is fixed on the rod 11 by means of a pin 20 with a slot, which passes through a radial hole in the rod 11.
    The engine works as follows.
    When power is not supplied to the stator winding 3, the pressure spring 13 presses the friction disks against each other. Between the rubbing surfaces of the disks, which may be conical or flat, a braking force arises which blocks the shaft 4.
    When power is applied to the stator winding 3, the magnetic field created by the current passing through the short loop ring 7, in combination with the magnetic field created by the stator winding 3 in the area of the additional stator pack 2, exerts an axial force on the axially movable element turn off the brake. The latter compresses the pressure spring 13, removing the blades of the fan 15 with a friction disk from another friction disk. Thus, the braking force disappears.
    To adjust the pressure of the discs, which determines the braking force, the pin 20 is removed and the nut 14 is rotated, screwed on the rod 11. As a result, the force of the pressure spring 13 is changed.
    The wear effect of the rubbing parts is corrected by a nut 19.
    The increase in the tractive force of the built-in electromagnetic brake is determined by the design of the magnetic core 9 of the axially movable element.
