The purpose of the invention is to increase the reliability of the engine.

Figure 1 shows a longitudinal section of the engine; Fig. 2 is the same; a cross-sectional view in Fig. 3 is the power supply circuit of the engine.

The engine consists of a housing 1 with six U-shaped cores 2 fixed in it, on which coils 3 of the windings of the core, two rotors 4 and the shaft 5 of the engine with a ferromagnetic disk b fixed on it are placed. The shaft 5 is mounted on bearings 7 in shields 8 housing. Each rotor 4 is mounted on a universal joint consisting of a ring 9, pins 10, pressed into sleeve 11, and two screws 12 (figure 2). Sleeve 11 of both hinges attached to the shields of the housing 8. The magnetic conductors of the rotors are made in the form of six L-shaped ferromagnetic rods 13, one end of which faces the ferromagnetic disk 6 and the other to one of the teeth of the U-shaped core 2 of the stator. The surfaces of the rods 13 and 2 of the rotor and the stator, facing each other, have a spherical shape with a center in the center of the universal joint. The structural elements of the rotor are non-instantaneous. The coils 3. motor core are included in the six-star circuit through valves 14 (Fig. 3) and are connected to a three-phase voltage source.

they are located one tooth over the L-shaped core of one rotor, and the other tooth over the L-shaped core of another rotor. When the stator windings 3 are turned on, the rotors 4 wrap around the end surface of the ferromagnetic disk, which remains sandwiched between them. Placing the winding 3 core on the stator eliminates the effects of vibrations on the winding. 3 pe.

The number of rods of the stator and rotor, respectively, the number of coils of the winding of the core, can be increased by a factor of K. In this case, each beam scheme (fig.Z)

will consist of K coils connected in series or in parallel.

 If the supply network is two-phase or single-phase with phase-shifting capacitance,

then the motor power supply circuit will be four-beam, similar to the power supply from the three-phase network.

The mounting of the rotors 4 is also possible on standard double-row spherical bearings, which allow the displacement of the axis of the inner ring relative to the outer one to 5 degrees. The rotor is locked against rotation around its axis in this case, with- |

by the power of a membrane coupling or gearing the rotor with a stator without a difference in the number of teeth.

The engine works as follows.

When the windings of the core 3 are turned on, the AC network through the valve circuit is energized at each instant of time through the coil circuit of one half of the stator. Magnetic fluxes

each stator coil closes through.

cuts U-shaped cores 2, spherical gaps between the rotor and stator, L-shaped cores 13 of the rotor 4 and ferromagnetic disk 6. In the working

35, the gaps between the rotors and the ferromagnetic disk 6 form a half-wave of a traveling magnetic field. The resulting electromagnetic force acting on each of the rotors 4 rotates with the synchronous frequency field. The rotors 4, remaining unmoving in the sense of rotation around their axes, roll the end surface of the ferromagnetic disk 6, which remains clamped between them. Due to the difference in the lengths of the rolling surfaces of the rotors 4 and the ferromagnetic disk 6, the latter rotates about its axis, rotating the motor shaft.

The motor can also operate in a step-by-step mode with DC power through the switch.

A motor with a rolling disk rotor as compared with the known one possesses a higher reliability. Placing the core winding on the stator eliminates the effect of vibrations on the winding, which, when the machine is operated for a long time, break the frame and inter-turn insulation. The small core length of the core, compared to a branched magnetic circuit in a known device, provides a smaller drop in the magnetic potential in steel and a smaller value of the scattered fluxes. This leads to a greater amount of induction in the working gap, and, consequently, of the electromagnetic moment.
