In this embodiment, when the electric device 2 does not drive the electric wheel 1 to rotate, the moving magnet 1c and the rotating magnet 3c are naturally disposed on a normal 10 defined by a rotating shaft 1a of the electric wheel 1 and a rotating shaft 3a of the magnetic moment wheel 3 together due to a magnetic attraction relationship, as shown in fig. 1 (only 1 moving magnet 1c and 1 rotating magnet 3c are marked in fig. 1 to clearly mark a structural relationship between the electric wheel 1 and the magnetic moment wheel 3); between the moving magnet 1c and the rotating magnet 3c when the electric wheel 1 is rotated by the electric device 2The magnetic field distribution is in a state of being affected by external Change as shown byThe moving magnet 1c generates a magnetic attraction force in the direction of the magnetic action line 13 to the rotating magnet 3c, and the magnetic attraction force can be decomposed into component forces in the direction of the normal 10 and the direction of the tangent 32, and the dynamic direction of the decomposition of the magnetic attraction force is schematically shown in fig. 4.

In the invention, the materials of the electric wheel 1 and the magnetic moment wheel 3 are selectedThey have different characteristics. The design requirement of the magnetic moment wheel 3 is that the magnetic moment wheel 3 has certain mass, so that a certain magnetic moment wheel rotating inertia can be compounded when the electric torque system outputs torque, and therefore, the magnetic moment wheel 3 is suitable to be made of nonmagnetic alloy with higher specific gravity; as the motorized wheel 1 for transmitting magnetic energy to the magnetic moment wheel, although the design is also required to have a certain mass, it is allowed to be manufactured by using a material having a relatively small specific gravity, for example, plastic steel, ABS or other solid forming material. The structure of electric wheel 1 and magnetic moment wheel 3 includes: one disc or a plurality of rings combined in a coaxial mannerBecome intoThe disc or the plurality of rings are fixedly connected into a whole through a structural fastener, and the integrated design and manufacturing are included. Fig. 5 is an example of a disc-shaped magnetic moment wheel 3 formed by combining two circular rings made of different materials, the material of the circular ring 3b2 is ABS, the material of the circular ring 3b1 is nonmagnetic alloy, and the combined disc has the advantages that the integrated design and manufacture of the rotating magnet body 3c and the circular ring 3b2 are convenient, and at the same time, the mass of the circular ring 3b1 is utilized to ensure that the magnetic moment wheel 3 has considerable inertia when rotating.

The electric wheel 1 and the magnetic moment wheel 3 are arranged adjacently, and the gap between the outer edge of the moving magnet 1c and the outer edge of the rotating magnet 3c, which are periodically opposite to each other, does not exceed 90mm, and the moving magnet 1c and the rotating magnet 3c are both located on a normal 10 determined by the rotating shaft 1a of the electric wheel 1 and the rotating shaft 3a of the magnetic moment wheel 3, and the schematic of the state is shown in a local part of fig. 1.

The angle of the electric device 2 in the electric torque system of the invention is a power source, and the electric device 2 can also be added with a control device for adjusting the rotating speed of the motor besides comprising a power battery and the motor; the mechanical transmission of the electric device 2 driving the electric wheel 1 to rotate belongs to the mature technology, generally comprises shaft fixed connection transmission and gear transmission, and can also be added with other auxiliary mechanical devices,however, the force application point of the mechanical transmission can not be designed on the rim of the electric wheel 11bIn this case, a preferred design is to select the transmission on the rotating shaft 1a of the electric wheel 1.

The embodiment of FIG. 1 only has 8 electromagnets 3c disposed on the magnetic moment wheel 3, which can increase the torque of the magnetic moment wheel due to the magnetic force, such as the one disposed on the magnetic moment wheel 3Rim 3b12 rotating magnets 3c are arranged on the magnetic bearing; similarly, of electric wheels 1Rim 1bIn the above, a larger number of moving magnets 1c can be additionally arranged, and the basic principle that m and n are equal needs to be grasped in design. The more moving magnets/rotating magnets on the electric wheel/magnetic moment wheel are arranged, the better the moving magnets/rotating magnets are arranged, and the number of the moving magnets/rotating magnets arranged on the rim is limited by the effective action range of the magnetic force of the rotating magnets and the moving magnets.

The optimal design of the electric wheel 1, the magnetic moment wheel 3, the moving and rotating magnets and the gap 4 is based on at least the following considerations: due to magnetic interaction of the magnets on the magnetic moment wheelNormal component force pairThe torque of the magnetic moment wheel does not contribute, and the so-called optimized design is an interaction relation determined by a plurality of factors such as the rotating speed interval of the electric wheel, the number of the moving magnets on the electric wheel and the rotating magnets on the magnetic moment wheel, the gaps 4 of the moving magnets and the rotating magnets which are periodically opposite to each other and the like, so that the magnetic action received by the rotating magnets on the magnetic moment wheel is cutComponent of forceTo the greatest possible extent, to facilitate the change in the state of the magnetic field distributionTo be transformed intoMagnetic moment wheelTorque of. In the same electric torque system, a plurality of magnetic moment wheels 3 are arranged to obtain larger inertia torque; similarly, for the same magnetic moment wheel, a plurality of electric wheels 1 are arranged, so that the magnetic moment wheel can obtain larger torque; a combined embodiment of configuring 2 magnetic moment wheels, 2 electric wheels in an electric torque system, as shown in fig. 6.

The electric torque system is different from the conventional technology in that the electric wheel 1 does not transmit mechanical energy to the magnetic moment wheel 3 in a mechanical transmission mode, and the energy transmission of the electric wheel to the magnetic moment wheel is realized by converting the magnetic force action of a moving magnet 1c arranged on the rim of the electric wheel 1 to a rotating magnet 3c arranged on the rim of the magnetic moment wheel 3 into the torque of the magnetic moment wheel 3; the torque output from the magnetic moment wheel 3 to the outside of the electric torque system through the rotating shaft 3a not only includes the torque based on the change of the magnetic field distribution stateTransformation ofTorque ofThe moment of inertia of magnetic moment wheel 3 is also added, and when magnetic moment wheel 3 has a certain mass and the speed of rotation of magnetic moment wheel 3 is sufficient, the moment of inertia of magnetic moment wheel 3 is not negligible.

The plurality of sets of power generation systems can be used in series, and the premise is that the output power of the plurality of sets of power generation systems is approximately the same; the plurality of sets of power generation systems can be used in parallel on the premise that the output voltages of the plurality of sets of power generation systems are the same.

The invention discloses a transmission technology of a conventional rotating generator, which is to transmit the rotating mechanical energy of a power device to a rotating shaft of the generator, and is different from the conventional transmission technology in that the energy action transmission of an electric wheel 1 to the rotating shaft of the generator is realized by acting energy on a permanent magnet of a rotating magnet 3c through a moving magnet 1c and adding the rotating inertia of a magnetic moment wheel, and when the magnetic moment wheel 3 has certain mass and enough rotating speed, the electric torque system can obtain larger torque through the rotating shaft 3a, so that the rotating generator driven by the electric torque system can obtain higher electric energy conversion efficiency.

The charging device is used for charging the energy storage battery, the conventional arrangement is adopted, the optimal scheme is to charge the energy storage battery by utilizing the electric energy output feedback of the power generation system, and the starting logic of the charging device is set according to different application requirements; the discharging load of the power generation system is not always in a full-load working state, time-distributed power fluctuation exists, and the electric energy which is not utilized by the discharging load can be fed back to the energy storage battery for charging through the charging device. The partial structure of the power generation system using the charging device to charge the energy storage battery in a feedback manner is shown in fig. 7.

The preferred examples are only recommended, a plurality of technical schemes can be partially used, or other mature technologies can be added or combined and used, and the basic aim of the technical scheme of the invention can be achieved only by the magnetic action relationship between the rotating magnet and the moving magnet according to the characteristic of the periodic magnetic force relationship between the magnetic moment wheel and the electric wheel.
