    The electric machine operates as follows.
    When current flows through the rods, electromagnetic forces arise. Since the conductors of different phases are placed in one housing, this reduces the intensity of vibration, the elastic elements and the robust housing in which the conductors are placed allow to reduce the intensity of the manifestation of vibration.
    The reduction of vibration can improve the safety of the proposed electric machine.

    1 The invention relates to electrical machines, namely to machines with a stator winding placed in the gap. The aim of the invention is to increase the safety of the machine. Fig, 1 shows a single-layer winding of the stator of the machine, cross section; FIG. 2 shows a two-layer coating of the stator of the machine; a cross-section in FIG. 3, an insulated body around the coil, a cross-section; The electric machine contains a rotor core (not shown), a core 1 of the stator 2, each of the rods 3 of the winding 4 contains a bundle of wires 5 with insulation 6, a cooling tube 7 is installed along the bundle of wires 5 A series of rods 3 are grouped together, forming coil 8, covered with an insulating layer 9, on the outer surface of the coil 8 is placed an elastic film 10 to absorb stator vibration. The coil 8 is placed and secured in an insulated body 11 made of reinforced reinforced plastics material, the body 11 is mounted and fixed on the inside Rennaya surface of the core 1 of the stator 2 by means of supporting means 12, performed protruding in the radial direction from the core 1 of the stator 2 and placed between separate insulated bodies. The housing 11 can be made of two parts 13 and 14. Between the part 13 and the core 1 of the stator 2, another layer of elastic film 15 can be expanded. The protruding elements 16 and 17 of the parts 13 and 14 of the housing 11 are installed in the pack 18 of the supporting means 12. The housing 11 can be divided around the circumference and glued. 1172 Electric machine works as follows. When current flows through the rods, electromagnetic forces arise. Since the conductors of different phases are placed in the same housing, this reduces the intensity of vibration, the elastic elements and the robust housing in which the conductors are placed, makes it possible to reduce the intensity of the manifestation of vibration. Reducing vibration allows for improved safety of the proposed electric machine.
