Referring to fig. 1, the magnetic pole line 3d of the permanent magnet arranged on the rotor in the prior art is arranged along the rim tangent line 6 or along the normal line 5. The recessed edge rotor 3 of the present invention has two main differences from conventional similar structure technology: first, the same rotating body is at least provided with two outer edges 3 b; second, the magnetic pole lines 3d of the permanent magnets 3c on the two outer edges of the rotating body are arranged in parallel along the direction of the rotating shaft 3 a.

Fig. 2a is a schematic structural diagram of the concave edge rotating body of the present invention, 4 permanent magnets 3c are equally arranged around two outer edges 3b at intervals, the permanent magnets are installed outside the outer edges 3b, a magnetic pole line 3d is parallel to the direction of the rotating shaft 3a, the side view structure of the concave edge rotating body is shown in fig. 2b, and the magnetic pole line 3d shown in the figure is a connecting line and an extension line thereof, which are determined by N, S two magnetic poles, of the permanent magnet 3 c. Permanent magnets are arranged on two outer edges of the concave edge rotating body and can be embedded into the outer edges, so that the outer arcs of the permanent magnets are overlapped with the outer peripheral surface of the outer edge 3b, and fig. 3a is an example that 8 permanent magnets 3c are embedded into the outer edge 3b in an alternate and even arrangement mode. The permanent magnets 3c distributed at the two outer edges 3b of the concave edge rotating body are preferably same in shape and evenly distributed at intervals, and are not limited in shape on the premise of not influencing installation; the permanent magnets can be arranged alternately in the same magnetic pole direction on the two outer edges of the concave edge rotating body, and can also be arranged alternately in an N-S magnetic pole alternating mode.

The base structure of the concave 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. 3b shows an example of a combined concave 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 concave edge rotator 3 rotates by using the mass (specific gravity of the material) of the ring 3b 2.

When the concave edge rotator operates, the motion trail of the permanent magnet 3c on the concave edge rotator is a closed circumferential line, fig. 4a is a preferred installation example of the concave edge rotator 3 and the electromagnetic device 1 (the magnetic pole line 3d in the figure is generated by the electromagnetic device 1 in an electrified state), and when the permanent magnet 3c on the concave edge rotator and the electromagnetic device 1 periodically face each other in rotation, the motion trail of the magnetic pole line 3d is coincided with the projection of the electromagnetic device 1, and the plan view schematic diagram is shown in fig. 4 b.

The magnetic core is provided with the gap 4 and is embedded and installed in the groove of the concave edge rotating body 3, the optimal design of fully utilizing electromagnetic energy is provided, only in terms of a magnetic transmission structural scheme, the magnetic core and the concave edge rotating body can be designed into an equivalent concave-convex type, but the electromagnetic device 1 consumes electric energy, only one electromagnetic pole generated by the magnetic core is utilized to be unreliable, the magnetic core is embedded and installed in the groove of the concave edge rotating body, and the magnetic energy of the two electromagnetic poles of the magnetic core can be fully utilized.

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 concave edge rotator defines a non-contact state, 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 small device is generally set to be 1-2mm, and the large and medium device is 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 signal at the reference instant 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 logic power supply 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. FIG. 5a shows a main circuit structure and logic control relationship between the logic power supply and the electromagnetic device; when the output power of the logic power supply 2 is large and the integrally designed logic power supply module cannot meet the use requirement, the switch circuit and the logic module can be separately designed for the control module to meet the requirement of high-power output, and a main circuit structure and a logic control relation of the control module which is separately designed and the electromagnetic device which is also used as a signal sensor are shown in fig. 5 b.

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 the electric device by an intelligent control technical method.

The logic power supply is provided with n pulse current cycles corresponding to one rotation cycle of the concave edge rotator, the n pulse current cycles are related to the number n of the permanent magnets of the concave edge rotator, for example, the two outer edges are respectively provided with 8 permanent magnets, and the logic power supply is provided with 8 pulse current cycles corresponding to each rotation cycle; each pulse current period can be provided with one power supply or two power supplies. The real-time rotational speed of the female rotor 3 depends on the time T of the pulse current period.

The permanent magnet rotates along with the concave edge rotating body to form a regular pulsating magnetic field and provide reference time information corresponding to the state that the permanent magnet is turned to a reference normal line 8, wherein the reference normal line 8 is shown in figure 6 a; the reference time information can be converted into an electric signal through a coil of an electromagnetic device or a special 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 maximum value time of the signal is judged as the reference time.

And supplying direct current in a T/2n time domain before the reference time or/and after the reference time, wherein the direct current does not comprise the power supply at the reference time. At the reference time, i.e. corresponding to the state where the real-time normal 5 coincides with the reference normal 8, the electromagnetic device 1 has no tangential component to the electromagnetic force of the permanent magnet 3c, and is not beneficial to the forward rotation of the concave-edged rotating body, as shown in fig. 6 b.

The logic power supply 2 controls the electromagnetic device 1 to generate a pulse electromagnetic pole of a magnetic pole line along the rotating shaft direction, so that the concave edge rotator obtains a forward rotation increment, and multiple technical meanings of an electrifying time domain, a current direction or a magnetic pole direction are implied: to achieve the forward rotation increment for the concave edge rotor, the electromagnetic poles energized before the reference time (corresponding to the forward rotation of the permanent magnet approaching the reference normal 8) are opposite in magnetic polarity to the opposing permanent magnet 3c, as shown in fig. 7 a; or the magnetic polarity of the electromagnet pole energized after the reference moment (corresponding to the permanent magnet going forward past the reference normal) is the same as the magnetic polarity of the opposing permanent magnet, as shown in fig. 7 b; otherwise, the forward turning increment of the concave edge turning body can not be obtained. 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 electrified 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 2 to the electromagnetic device 1 can be calculated according to the movement model of the gap 4 and the permanent magnet on the concave edge rotating body, and 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 concave 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 a limited technical scheme and is preferred by a designer in a limited T/2n time domain. Fig. 8a 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. 8b 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 can be seen that the electromagnetic force corresponding to the forward rotation of the concave edge rotating body simultaneously has a tangential component force (gain source) and a normal component force (no gain), which cancel each other, when θ is 45 degrees, the normal component force is the same as the tangential component force, and θ is the largest at 90 degrees; the principle of the optimized design is to use more tangential component force and to do less useless work.

The deformation design forms of the concave edge rotating body are numerous, the concave edge rotating body comprises different disc body designs, a plurality of concave edge rotating bodies are combined with a rotating shaft, a plurality of electromagnetic devices can be arranged for matching, and a plurality of logic power supplies of the plurality of electromagnetic devices are controlled in a combined mode.
