Description

The invention relates to electrical engineering, to electric motors and to mechanisms for its use.

Electric motors of the stator-rotor design on one axis have a number of disadvantages. Namely, the mass of the stator does not participate in the mechanical work on rotation, through the stator the electric motor loses half the force of the electromagnetic fields aimed at rotating the rotor. In the traction version, electric motors operate with an additional reduction gear.

Technical result, operation of the presented Andronov II electric motor, based on the design of the electric motor, consisting of six rotors on their shafts, installed on the axes X, Y, Z, X', Y', Z'. Patent of the Russian Federation 2664560.

The basic principles of operation of an electric motor for rotation of shafts 1, with rotors 2 located on axes X, Y, Z, X', Y', Z', Fig. 1, electromagnetic segments 19 Fig. 8, installed in rotors Fig. 7, in windows formed by the base of rotor 3, posts 18 and fastened with ring 17.

Actions of rotor segments located in the working zone of electromagnetic fields 26 Fig. 9.

Electromagnetic segments in position A of Fig. 13, electric energy in coils 25 of Fig. 8, forms magnetic fields in segments with opposite values, segments under the influence of magnetic fields with rotors move to position B.

Rotation of rotors by 1/16 of a revolution is completed. In position B in one electric segment, by means of power supply, the polarity of the magnetic field changes to the opposite value, magnetic fields move segments with rotors to position B by 1/16 of a revolution, the actions of electromagnetic fields turn rotors with shafts. 1/16+1/6, by 1/8 of a revolution in opposite directions.

Structurally and physically, under the influence of magnetic fields, the rotation of the rotors occurs without a stator.

In an electric motor, all rotors are identical. The electrical part of the rotors is connected to electrical circuits 27, 24, 28, coming from the ECU 29 Fig. 11. Electric power from line 27 with an unchanging polarity value through the electric brush 20 Fig. 5, Fig. 6, Fig. 12 through the lamellas 3 of the slip ring 22 is supplied to the coils 25 of the electric segments Fig. 8 with internal numbers in the rotor C3 and C7. Electric line 24 through the electric brush to the slip ring 23, is constantly connected with the electric segments. Electric power from line 28, with changing polarity, through electric brush 21 goes to lamellas 5 of current-collecting ring 22, then to electric segments C5 and C1 and the electromagnetic fields in the rotors act on rotation, according to the cartogram of Fig. 13, turning the rotor by 1/8 of a turn together with the current-collecting rings. Electric power on brushes 20 and 21 goes to the next lamellas 4 and 6 of current-collecting ring 22. Electric power goes to electric segments C4, C8 and C6, C2, the rotors continue to rotate. For a full turn of the rotors, the electromagnetic segments receive electric power eight times from lines 27 and 28 with constant and changing polarity, which corresponds to the generation frequency F=8 Hz per turn. Timely switching of the polarity of electric power on line 28 is controlled by rotor position sensor 14 of Fig. 3. ECU 29 operates on the principle of pulse-width modulation of electric power with a duty cycle changing from 0 to 100%. Fig. 11.

Fig. 10 shows the working zones of magnetic fields with changing polarity from line 28 and non-changing polarity from line 27, on the visible sides of the rotors standing on the axes X, Y, Z, on the axes X', Y', Z' - mirrored. The configuration of the magnetic fields of the electric segments in the rotors of Fig. 10 corresponds to the cartogram of Fig. 13.

The housing block 10 Fig. 2 centers the rotor shafts 1 Fig. 5 along the axes X, Y, Z and X', Y', Z' Fig. 1, and synchronizes the rotation of the rotors 2 Fig. 1 with the rotor shaft gears 4 Fig. 1 by the intermediate gears 6 Fig. 2 on their shafts 7 Fig. 2 installed in the block in the direction from the vertices 8 to the center 9, where they are fastened together. The gears 6 rotate around their axes and are jointed by their teeth with the gears 4 of the rotor shafts Fig. 4 as follows: one rotor gear with two intermediate gears with an angular engagement of the teeth along the circumference of 180° - 180°. One intermediate gear with three rotor shaft gears with an angular engagement of the teeth along the circumference of 120°-120°-120°, the conical angle of all gears is 32°. Forced lubrication of gears through the tops of the motor housing 12 Fig.9, into the tops of the block housing 10 Fig.2 is allowed. The electric motor does not interfere with operation on rotor shafts, from one to six inclusive. With simultaneous and equal M on six rotor shafts, the dynamic load on the teeth of all gears in block 10 is zero.

The design of the motor includes electric brushes, the wear of which depends on the speed of rotation of the rotors and the amount of electricity through them. The speed of rotation for abrasion is eight times less, and the electricity is less.

The electric motor in the traction version works without a gearbox on the basis: the rotors with shafts under the influence of electric power 1E1F make 1/8 of a revolution. Electric power 1E8F will turn the rotors with shafts by one revolution (1ω), while receiving an eightfold force of the magnetic field (8S) for rotation. The result in a load of 34 is equal to the productivity of 1M.

Fig.16 and Fig.17 show the results of the performance of electric motors with equal Q - losses of electromagnetic and mechanical friction.

The design of the electric motor, consisting of rotors with a cone of the working sides of the rotors of 90° Fig. 5, Fig. 7, rotate on their axes X, Y, Z and X', Y', Z' with a setting angle of the axes of 90°.

Outside zone 26, the magnetic fields of the rotor segments are at an angle of 90°.

Magnetic fields, regardless of polarity, at an angle of 90° are neutral and do not create electrical countercurrents.

There is no practical evidence of the absence of back EMF for this engine design.
