Detailed Description

The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and examples.

In the prior art, there are many designs of the turntable with permanent magnets, but the magnetic pole line 3d of the permanent magnet 3c is arranged along the tangential line 6 of the rim, or along the normal 5, as shown in fig. 1. The rotating disc with the permanent magnet is usually driven by a magnetic wheel, the magnetic wheel is correspondingly provided with a plurality of permanent magnets at the outer edge, the permanent magnets on the magnetic wheel are driven by a rotating motor to rotate along the wheel edge part, and the rotating wheel is rotated under the action of periodic magnetic force.

The technical scheme of the invention for driving the magnetic edge rotator 3 does not adopt a conventional magnetic force wheel, but adopts a mode that a control wheel acts along the action of electromagnetic force to drive, and the design scheme of a permanent magnet on the magnetic edge rotator 3 is different from the conventional scheme.

The magnetic pole line 3d of the permanent magnet 3c arranged on the magnetic edge rotating body 3 is arranged along the direction of the rotating shaft 3a, fig. 2a is a structural schematic diagram of the magnetic edge rotating body, 4 permanent magnets 3c are evenly distributed around the outer edge at intervals, the permanent magnets are installed outside the outer edge 3b, the magnetic pole line 3d is parallel to the direction of the rotating shaft 3a, the side view structure of the magnetic pole line is shown in fig. 2b, and the shown magnetic pole line 3d is a connecting line and an extension line thereof determined by N, S two magnetic poles of the permanent magnet 3 c.

The permanent magnet 3c is arranged on the magnetic edge rotator 3 and can also be embedded into the outer edge, so that the outer arc of the permanent magnet is overlapped with the outer peripheral surface of the outer edge, and fig. 3a is another example of 8 permanent magnets 3c embedded into the outer edge 3b in an alternate and even arrangement mode. There are also several variants of the magnetic edge rotor 3, for example, the outer edge of the rotating blade has a circular rotation path, and the arrangement of permanent magnets on the outer edge 3b also constitutes a magnetic edge rotor 3 according to the present invention, as shown in fig. 3 b. The permanent magnets are preferably the same in shape and evenly arranged at equal intervals, and are not limited in shape on the premise of not affecting installation, and the outer edge of the magnetic edge rotating body 3 can be alternately arranged in the same magnetic pole direction or in an N-S magnetic pole alternating mode.

The base structure of the magnetic edge rotator comprises: the disc or the rings are combined, the rings are combined into the disc in a coaxial mode, or the rings are fixedly connected into a whole through fasteners, and the disc or the rings are designed and manufactured integrally. Fig. 4 is an example of a combined magnetic edge rotator 3, where the material of the ring 3b1 is ABS and the material of the ring 3b2 is nonmagnetic alloy, which has the advantages of facilitating the integrated manufacturing process of the ring 3b1 and ensuring considerable inertia when the magnetic edge rotator 3 rotates by using the mass (specific gravity of the material) of the ring 3b 2.

When the magnetic edge rotator operates, the rotating track of the permanent magnet 3c on the magnetic edge rotator is a closed circumferential line, fig. 5a is a preferred installation example of the magnetic edge rotator 3 and the electromagnetic device 1 (the magnetic pole line 3d in the figure is generated when the electromagnetic device 1 is in an electrified state), and when the permanent magnet 3c on the magnetic edge rotator 3 periodically opposes the electromagnetic device 1 in rotation, the magnetic pole line 3d of the permanent magnet is projected to coincide with the electromagnetic device 1, and the plan view schematic of the magnetic edge rotator is shown in fig. 5 b.

The electromagnetic device 1 has the function of converting direct current into electromagnetic poles, and the magnetic core is a magnetic medium material which can generate stronger additional magnetic field under the action of external magnetic field and is well known to those skilled in the art, and is preferably a product with higher magnetic permeability; the coil usually uses copper wire or copper-plated aluminum core wire, and the more turns, the stronger the electromagnetic action. The gap 4 between the electromagnetic device and the magnetic edge rotator defines the non-contact, and the technical requirements on the gap are implied. It is known in the art that the gap of magnetic action, also called air gap, is an energy channel for transferring magnetic action between magnets, the smaller the gap is, the more beneficial the magnetic action transfer is, the value is related to the magnetic permeability of a magnetic core, the number of turns of a coil, the energizing strength and the magnetic flux of a permanent magnet, the medium and small devices are generally set to be 1-2mm, and the large and medium devices are generally set to be 2-20 mm.

At least one group of coils of the electromagnetic device 1 is arranged, and the coils comprise one group and are also used as electromagnetic force coils and signal sensors; since the electromagnetic force coil functions to generate an electromagnetic pole and the signal sensor functions to obtain a signal at a reference time, a practical design is often provided with two or more sets, one or more sets serving as the electromagnetic force coil, and the other one or more sets serving as the signal sensor. The signal sensor is not limited to the use of magneto-electric modules, and the relative position signal of the permanent magnet can be obtained as well, for example, using an electro-optical signal element. According to the requirements for signal precision and reliability, the logic power supply can be correspondingly provided with one or more signal input ends corresponding to the number of the signal sensors.

The logic power supply 2 stores logic control program, which is conventionally realized by logic digital technology and related operational circuit, and its control module generally includes: the switch circuit, the logic interface circuit, the microprocessor and the signal input processing circuit which are internally stored with logic control programs and the peripheral circuit can carry out corresponding digital-to-analog conversion through the input sensing signal and control and output time sequence current according to set logic. At present, a plurality of integrated control module products exist in the market, and the working logic requirements can be generally met through programming as long as the memory space and the design power meet the use requirements. A circuit structure and a logic control relationship between the logic power supply and the electromagnetic device are shown in fig. 6 a; when the output power of the logic power supply is large and the integrally designed module cannot meet the use requirement, the switch circuit and the logic module can be designed separately for the control module to meet the output requirement of high power, and the circuit structure and the logic control relation of the electromagnetic device which is designed separately for the control module and is also used as the signal sensor are shown in fig. 6 b.

The logic power supply 2 is correspondingly provided with n pulse current cycles corresponding to one rotation cycle of the magnetic edge rotating body 3, and the n pulse current cycles are related to the number n of permanent magnets arranged at the outer edge of the magnetic edge rotating body, for example, the outer edge of the magnetic edge rotating body is respectively provided with 8 permanent magnets, and the logic power supply is correspondingly provided with 8 pulse current cycles corresponding to each rotation cycle of the magnetic edge rotating body; each pulse current period can be provided with one power supply or two power supplies.

The permanent magnet 3c forms a regular pulsating magnetic field at the outer edge 3b along with the rotation of the magnetic edge rotator 3, and provides time information of the front rotation to a reference normal line 8, wherein the reference normal line 8 is determined by a position connecting line of a rotating shaft 3a of the magnetic edge rotator and the magnetic core, as shown in fig. 7 a; the reference time information can be converted into an electric signal through a magnetoelectric induction coil of an electromagnetic device or a specially arranged signal sensor, even if the signal precision is relatively low, the logic power supply can still obtain the electric signal with the strength normally distributed along with the time, the maximum value of the signal can be obtained in the state that the real-time normal line 5 is superposed with the reference normal line 8, and the time of the maximum value of the signal is judged as the reference time.

The logic power supply 2 supplies direct current in the time domain of T/2n before the reference time or/and after the reference time, excluding supplying power at the reference time. At the reference moment, the electromagnetic device 1 has no tangential component to the electromagnetic force of the permanent magnet 3c, and is completely useless for the forward rotation of the magnetic edge rotator, and the corresponding motion state is shown in fig. 7 b.

The control electromagnetic device 1 generates a pulse electromagnetic pole of a magnetic pole line along the direction of the rotating shaft to enable the magnetic edge rotator to obtain forward rotation increment, and multiple technical meanings of an electrifying time domain, a current direction or a magnetic pole direction are implied: to make the magnetic edge rotator obtain forward rotation increment, the electromagnetic pole electrified by the electromagnetic device before the reference time (corresponding to the forward rotation of the permanent magnet approaching the reference normal 8) is opposite to the magnetic polarity of the opposite permanent magnet 3c, as shown in fig. 8 a; or the electromagnetic pole energized after the reference moment for the corresponding electromagnetic device (corresponding to the permanent magnet going forward past the reference normal 8) is the same magnetic polarity as the opposing permanent magnet, as shown in fig. 8 b; otherwise, the magnetic edge rotator can not obtain forward rotation increment. The technical meaning of providing direct current in the T/2n time domain before and after the reference time is that the electromagnetic device can be powered on twice in one pulse current period (respectively corresponding to the situation that the permanent magnet approaches to the reference normal line and crosses the reference normal line before).

The time domain of the power supply of the logic power supply to the electromagnetic device can be calculated according to the gap 4 and the motion model of the permanent magnet on the magnetic edge rotating body, and the engineering people are more prone to experimental determination. The logic power supply 2 is limited to set n pulse current cycles corresponding to one rotation cycle of the magnetic edge rotator 3, and the existence of the gap 4 determines that the starting power-on time cannot exceed the T/2n time domain before the reference time, and the stopping power-on time cannot exceed the T/2n time domain before the reference time; the designer may prefer the start/stop power-on timing according to specific design conditions.

The time of each power-on is less than T/4n, which is the technical scheme defined by the invention and is preferred by a designer in a defined T/2n time domain. Fig. 9 is a schematic diagram of the tangential and normal component directions of the permanent magnet 3c approaching the magnetic force line 9 between the reference normal 8 and the electromagnetic device 1 and the vector dynamic included angle θ thereof, fig. 10 is a schematic diagram of the tangential and normal component directions of the permanent magnet 3c crossing the magnetic force line 9 between the reference normal 8 and the electromagnetic device 1 and the vector dynamic included angle θ thereof, and it is seen that the electromagnetic force corresponding to the forward rotation of the magnetic edge rotator exists, and simultaneously the tangential component force (gain source) and the normal component force (no gain) coexist, which cancel the difference, when θ is 45 degrees, the normal component force is the same as the tangential component force, and θ is 90 degrees, the tangential component force is the largest; the principle of the optimized design is to use more tangential component force and to do less useless work.

In the invention, the logic power supply has any power source form, the technical meaning is not limited, the power source can be mains supply alternating current, wind energy, solar energy or primary batteries and secondary batteries, and the logic power supply comprises a power supply collected at a load end of an electric torque device by an intelligent control technical method.
