Detailed Description

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

Concave edge turn 3 and prior art take the magnetism to turn the structure have two main differences: one is that at least two outer edges 3b are arranged on the same concave edge rotating body; secondly, the magnetic pole lines 3d of the permanent magnets 3c on the concave edge rotator 3 are arranged in parallel along the direction of the rotating shaft 3a, while the magnetic pole lines 3d of the permanent magnets 3c on the conventional magnetic rotator are arranged along the direction of the rim tangent 6 or along the direction of the normal 5, as shown in fig. 1. Fig. 2a is a schematic structural diagram of the concave edge swivel, which surrounds 4 permanent magnets 3c arranged at two outer edges 3b at intervals, the permanent magnets are installed outside the two outer edges, the magnetic pole line 3d is parallel to the direction of the rotating shaft 3a, the side view structure is as shown in fig. 2b, and the shown magnetic pole line 3d is a connecting line and an extension line thereof, which are determined by N, S two magnetic poles, of the permanent magnet 3 c.

The permanent magnets are arranged on the concave edge rotating body and can be embedded into the outer edge, so that the outer arcs of the permanent magnets are overlapped with the outer peripheral surface of the outer edge 3b, and fig. 3 is another example that 8 permanent magnets 3c are embedded into the outer edge 3b in an alternate and even arrangement mode. The permanent magnets distributed at the two outer edges of the concave edge rotating body are preferably same in shape, are uniformly 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 3b of the concave edge rotating body, and can also be arranged alternately in an N-S 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. 4 is an example of a combined concave edge rotator 3, 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 process manufacture of the ring 3b1, and at the same time, using the mass (specific gravity of the material) of the ring 3b2 to ensure that the concave edge rotator 3 has considerable inertia when rotating.

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. 5a is a preferred installation example of the concave edge rotator 3 and the electromagnetic device 1 (in the figure, the electromagnetic polar line 3d of the electromagnetic device 1 is generated when the electromagnetic device 1 is in a power-on state), when the permanent magnet 3c on the concave edge rotator 3 and the electromagnetic device 1 periodically face each other in rotation, the polar line 3d of the permanent magnet is projected and overlapped with the electromagnetic device 1, and in this state, the maximum value of the magnetic interaction between the permanent magnet and the electromagnetic device 1 can be obtained, and the plan projection of the maximum value along the direction of the rotating shaft is shown in fig. 5 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 known to those skilled in the art, and is preferably a high-permeability product; the magnetic core is in any shape, such as a strip shape and a concave shape; 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, including one group, and the coils are used as electromagnetic force coils and magnetoelectric induction coils; since the electromagnetic force coil functions to generate an electromagnetic pole and the sensing coil functions to obtain a position signal of the permanent magnet through electromagnetic induction, a practical design is often provided with more than two groups, one group or more than one group is used as the electromagnetic force coil, and the other group or more than one group is used as the sensing coil. 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 of 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 control module of the logic power supply 2 stores a logic on/off control program, which is conventionally realized by adopting a logic digital technology and a related operational circuit, and the sub-modules of the logic power supply generally comprise: 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, more logic power supply products exist in the market, and the working logic requirements can be generally met through programming as long as the control precision and the memory space of a microprocessor are met. A circuit structure and a control relationship among the logic power supply, the electromagnetic device and the signal sensor are shown in fig. 6 a; when the logic power supply has larger power and the integrally designed logic power supply control module cannot meet the use requirement, a special switch circuit can be designed to meet the power requirement, the switch circuit and the logic module are separately designed for the control module, and the circuit structure and the control relation of one electromagnetic device which is also used as a 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 concave edge rotating body 3, and is related to the number n of permanent magnets at the outer edge of the concave edge rotating body, for example, two outer edges of the concave edge rotating body are respectively provided with 8 permanent magnets, and the logic power supply 2 is correspondingly provided with 8 pulse current cycles corresponding to each rotation cycle of the concave edge rotating body 3; 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 concave edge rotator 3, and provides position information of the front of the permanent magnet to a reference normal line, and the reference normal line 8 is shown in fig. 7; the position information can be converted into an electric signal by a coil of the electromagnetic device 1 or a signal sensor provided specially, and the electric signal can be used as a reference time for controlling the energization of the electromagnetic device 1 by the logic power supply 2. Even if the accuracy of the signal sensor is relatively low, the logic power supply 2 can still obtain an electric signal with the strength normally distributed as a function of time, the maximum value of the signal can be obtained before the permanent magnet 3c is shifted to the reference normal line 8, and the time corresponding to the maximum value of the signal is determined as the reference time.

And pulse direct current is provided in the time domain of T/2n before the reference time or/and after the reference time, and power supply at the reference time is not included. The electromagnetic force supplied by the electromagnetic device 1 at the reference moment (corresponding to the moment before the permanent magnet 3c is turned to the reference normal line 8) has no tangential component on the permanent magnet 3c and no benefit on the moment before the concave edge turning body, as shown in fig. 8. The forward turning increment obtained by the concave edge rotator implies multiple technical meanings of the electrifying time domain, the current direction or the magnetic pole direction of the electromagnetic device 1: the forward shifting increment is obtained by that the magnetic polarities of the electromagnetic pole and the opposite permanent magnet 3c are opposite before the reference time (corresponding to the forward shifting of the permanent magnet approaching the reference normal line 8) (as shown in fig. 9 a), or the magnetic polarities of the electromagnetic pole and the opposite permanent magnet 3c are the same after the reference time (corresponding to the forward shifting of the permanent magnet beyond the reference normal line 8) (as shown in fig. 9 b); otherwise, the electromagnetic pole cannot make the concave edge rotor 3 obtain forward turning increment. The time domain T/2n before and after the reference time provides pulsed direct current, meaning that the electromagnetic device 1 can be energized twice in one pulse current period (corresponding to approaching and crossing the reference normal 8 before the permanent magnet, respectively).

Under the technical conditions that the energization time of the logic power supply 2 to the electromagnetic device 1 is less than T/4n in a limited T/2n time domain, the starting/stopping energization time can be calculated according to the movement model of the gap 4 and the permanent magnet on the concave edge rotating body, and the engineering people are more prone to experimental determination. Due to the presence of the gap 4, it is decided that, on the limited premise that the logic power supply 2 sets n periods of pulse current for one period of rotation of the notch rotor 3, when it is energized before the reference time: the starting power-on time cannot exceed the T/2n time domain before the reference time, and the stopping power-on time belongs to the technical optimization scheme; when power is applied after the reference time: the cut-off power-on time cannot exceed the T/2n time domain before the reference time, and the start-up power-on time belongs to the technical preferable scheme.

The power-on time of each time is less than T/4n, which is the technical scheme defined by the utility model and is preferred by the designer in the limited T/2n time domain. On the concave edge rotating body 3, the tangential and normal component directions and the vector dynamic included angle theta of the permanent magnet 3c approaching the magnetic force line 9 between the reference normal line 8 and the electromagnetic device 1 are shown in fig. 10a, the tangential and normal component directions and the vector dynamic included angle theta of the permanent magnet crossing the magnetic force line between the reference normal line and the electromagnetic device are shown in fig. 10b, it can be seen that the corresponding concave edge rotating body rotates forwards while the tangential component force (gain source) and the normal component force (no gain) coexist, the cancellation length is long, when theta is 45 degrees, the normal component force and the tangential component force of the electromagnetic force are the same, and theta 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.

In the specific design, attention is paid to the relationship between each rotation period of the concave edge rotator 3 and the preset real-time rotation period time T, the rotation period time T, that is, the time of each rotation period of the concave edge rotator, implies the rotation speed and the frequency of the logic power supply 2 for providing the periodic pulse current, and the logic power supply 2 can control the concave edge rotator 3 to operate at the preset real-time rotation speed by controlling the frequency of the periodic pulse current provided to the electromagnetic device 1.

Logic power supply's power source form is arbitrary, and the technical meaning is for not establishing the restriction, and the source of power can be the city net alternating current, also can be wind energy, solar energy or primary battery and secondary cell, include the power of collecting through intelligent control technical method at the load end that electronic concave edge turned.

The preferred examples are only recommended, and a plurality of technical schemes can be partially used, or other mature technologies can be added or combined. The deformation design form that the concave edge turned is numerous, including different disk body designs, set up a plurality of concave edge with the pivot combination and turn, also can set up a plurality of electromagnetic means and match to and a plurality of logic power supply combination control are separated to a plurality of electromagnetic means, and this type of deformation is implemented and is understood for technical personnel in the field easily.
