Abstract

The invention relates to electrical engineering and can be used in a low-speed, low-inertia electric drive. The aim of the invention is to increase efficiency. The engine consists of a housing 1 with sections 2 of the core windings fixed therein, two rotors 4 with laminated magnetic cores in the form of an annular frame 5 with end teeth 6. The rotors 4 are mounted on hinges so that the teeth 6 of their magnetic cores fit into the holes of the winding sections 2 and occupied a middle position in them. A ferromagnetic disk 13 is placed between the rotors 4 on the motor shaft 11. When sections 2 of the winding of the core are turned on, alternating current circuits through the valve circuit are at one time the sections of one half of the stator. The magnetic flux of each section is closed through the prong 6, covered by this section, the working gap, ferromagnetic disk 13, opposite tooth 6 of the other rotor 4, rm 5 and adjacent teeth of both rotors 4. Under the action of the resulting electromagnetic force, the rotors roll around the end surface of the ferromagnetic disk sandwiched between 13, remaining stopped from rotation around its axis. In the electric motor, there are no additional non-working gaps in the path of the main magnetic flux of the core, the flow is closed along a relatively short magnetic conductor, the passage is minimal working gaps, which leads to low power consumption and, consequently, higher efficiency. 3 il.

Description

The invention relates to electrical engineering and can be used in a low-speed, low-inertia electric drive.

The purpose of the invention is to increase efficiency.

FIG. 1 shows an electric motor, a longitudinal section; FIG. 2 is a section A-A in FIG. 1 j in FIG. 3 - power supply circuit of the engine.

I

The engine consists of body 1

(Fig. 1) with twelve coils of sections 2 of the core winding fixed in it (sections 2 are pairwise combined into two disk holders 3 filled with epoxy compound, six coils each, and inserted into the housing 1), two rotors 4 with laminated magnesium - ground pipes in the form of an annular rome 5 with six end teeth 6. The rotors 4 are mounted in the housing 1 on cardan hinges consisting of ring 7, two pins 8, pressed into sleeve 9, and two screws 10. The sleeves 9 of both hinges are fixed in the housing 1. The rotors 4 are mounted on hinges so that the teeth 6 of their ma nitoprovo- rows included in the opening sections of the coils 2 and held in their center position. On the shaft 11 of the engine mounted in the housing 1 on the bearings 12 is fixed ferromagnetic disk 13, placed between the rotors 4, the design elements of the rotor 4 is made non-magnetic. The coils of sections 2 of the motor core are included in the scheme of the neck of a ray star through valves 14 and are connected to a three-phase voltage source. Coils of sections 2 belonging to one beam of the circuit, encompassing 5

opposite teeth of the magnetic conductors of different rotors. All coils are turned on according to i. when current flows from the beginning of the coils to their ends, the magnetic fluxes of the anti-obstruction teeth, belonging to different rotors, fold and have the same direction in the respective teeth.

The number of teeth of each rotor and, accordingly, the number of coils of the winding section of the core can be increased n times. In this case, each beam of the circuit will consist of n coils connected in series or in parallel. If the power supply network is two-phase or single-phase with phase-shifting capacitance, then the power supply circuit will be four-beam, similar to the power supply circuit from the three-phase power supply network. The number of coils can be reduced by half, while the remaining coils will cover the teeth of only one rotor.

The engine works as follows.

When the coils of section 2 of the winding of the core are turned on, the coils of one half of the stator are energized at each moment of time through the valve circuit (Fig. 3). The magnetic flux of each coil closes through the prong 6, covered by this coil, the working gap, ferromagnetic disk 13, opposite tooth 6 of the other rotor 4, rm 5, adjacent teeth of both rotors 4. A running magnetic field is formed in the working gaps between the rotors 4 and the ferromagnetic disk 13 , concentrated only in half the active zone of the machine. Under the effect of the resultant

electromagnetic force due to this field, the rotors rotate the end surface of the ferromagnetic disk 13 sandwiched between them, remaining stopped from rotation around its axis. Due to the difference in the lengths of the rolling surfaces of the rotors 4 and the ferromagnetic disk 13, the latter rotates around its axis, rotating the shaft 11 of the engine.

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

To increase the engine life, reduce the noise level and provide the required reduction ratio to the rotors, annular track tracks can be installed on the rotors, by which each of the rotors rests on the disk 13. At the same time, a certain minimum gap can be maintained between the ferromagnetic teeth 6 and the disk 13.

In the proposed engine with a rolling disc rotor in the path of the main magnetic flux of the core, there are no additional non-working gaps, the flow is closed relative to one another.

short circuit, the passage of the minimum operating clearances, which leads to a low consumption compared with the known motor magnetizing current, and hence a higher efficiency.
