Description

Disc Motor/Generator with Railed Stator

technical field

An outer disc motor, particularly a disc motor/generator with a railed stator.

Background technique

A common permanent magnet AC servo motor 9, as shown in FIG. 1, is to set the permanent magnet 91 at the rotor of the outer layer of the motor, and set the armature coil 93 at the stator of the core. It is difficult to dissipate the heat of the pivot coil due to the resistance, or the sudden heat when the current jumper occurs during the commutation process; and due to the limited structure design of the inner and outer layers, the output torque changes, The elasticity of its strain is also reduced when problems such as installation space constraints are encountered.

On the other hand, since the operation of the motor mainly depends on the attraction of opposite poles and the repulsion of the same poles, the distribution of magnetic field lines plays a decisive role in the operation of the motor. Because the magnetic resistance of air is very high, if the permanent magnet device and the iron core in the coil occupy a lower proportion of the path in the closed loop, the longer the air area passes through, the magnetic resistance will be greatly increased, and the magnetic flux will be dispersed, and the effect will be reduced. efficiency also decreases. A known disk generator 8, as shown in FIG. 2, although the motor structure of the disk outer rotor 81 is disclosed, but there is no proper solution to the above-mentioned problems of heat generation and energy consumption. In addition, the number of permanent magnets and coils 83 is not properly matched, which will also cause the magnetic circuit to not function uniformly, and may cause uneven rotation of the output force in each action cycle.

On the other hand, as long as the motor converts kinetic energy into electrical energy in reverse, it is a generator. But in the same way, how to properly utilize the interaction between the coil and the permanent magnet, so that the magnetic induction caused by kinetic energy can be effectively converted into electrical energy output and storage, also requires a good structural design to reduce the magnetic resistance between the magnet and the iron core.

How to reduce the gap between the magnetic pole and the iron core of the permanent magnet, and form an appropriate magnetic circuit, so that the magnetic flux is concentrated in the expected path to avoid divergence, and how to properly use the time-varying driving signal to form an efficient interaction between the electromagnet and the permanent magnet It can improve the energy conversion efficiency of the motor, and also provide better energy conversion efficiency when it is used as a motor in reverse, which is the problem to be solved by the present invention.

Detailed ways

The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiments in conjunction with the accompanying drawings; label representation.

A first preferred embodiment of a disc motor/generator with a rail-type stator of the present invention, please refer to FIGS. 3 to 6 together, the outer disc motor 1 has a pivot shaft 12 extending along an axial direction , for the convenience of description, the aforementioned axial direction is defined here as the up-down direction along the drawing, and two disk-type outer rotors 14 arranged in parallel with each other, each disk-type outer rotor 14 respectively includes a base body 141 and an even number of permanent disks The magnets 143 are, in this example, six permanent magnets 143 as an example. In addition, the bases 141 in this example are all circular disks, and are respectively vertically fixed to the pivot shaft 12 with their symmetrical centers.

In this example, the aforementioned permanent magnets 143 are flatly embedded in the aforementioned base body 141 in a slightly long, flat, curved arc shape, and the two magnetic poles N and S of each permanent magnet 143 are not only arranged at the aforementioned base body 141, but also adjacent to each other. The two permanent magnets 143 are arranged in such a way that the N poles are close to each other or the S poles are close to each other. As can be easily understood by those skilled in the art, even if the permanent magnet here is changed to other shapes such as horseshoe or rectangle, as long as it is disposed on the base body 141 in the aforementioned manner, it will not hinder the implementation of the present invention. And because the permanent magnets 143 in this example are in the shape of an arc, the arc shape of the magnet just makes the magnets and the magnetic poles co-located on a circle 121 with the pivot 12 as the center and evenly arranged. The opposite arrangement of the outer rotor 14 is such that the same magnetic poles of the permanent magnets 143 are arranged to face each other.

The above-mentioned outer disc motor 1 also includes a set of railing-type stators 16. In this example, the group of railing-type stators 16 includes nine bud-shaped iron cores 161. For the sake of illustration, the bud-shaped iron cores 161 are further distinguished here. The main body 166 is arranged substantially parallel to the direction of the pivot shaft 12 , and at least two buds 165 extend from the main body 166 and are substantially orthogonal to the main body 166 . The branch buds 165 in this example only extend from the same side of the main body 166, so that the branch bud-shaped iron core 161 in this example has a shape similar to the Greek letter "π" when viewed from the side. The lengths of 166 are all 3.5 cm. In this example, the iron core 161 is explained as being composed of a plurality of silicon steel sheets, thereby reducing the effect of eddy currents, and is jointly held by a non-magnetically conductive stator base 164 . Of course, those with ordinary knowledge in the technical field of the present invention can also arbitrarily select, for example, iron powder die-casting or other conventional magnetic conductors as the iron core, which does not hinder the implementation of the present invention.

The main bodies 166 of each of the aforementioned iron cores 161 are arranged parallel to each other along the aforementioned axial direction, and are evenly distributed at a circular tube 123 with the aforementioned pivot shaft 12 as the center of the circle. In the figure, the connection line between each body 166 and the pivot shaft 12 and the included angle between the connection line between the adjacent body 166 and the pivot shaft 12 are respectively 30 degrees, and the two poles of the body 166 of each iron core 161 are close to corresponding to the aforementioned two As for the permanent magnets 143 of the outer disc rotor 14, since the number of iron cores 161 in this example is 1.5 times that of the permanent magnets 143, no matter where the outer disc rotor rotates to any position, some permanent magnets 143 may correspond to exactly two permanent magnets 143. The main bodies 166 of the adjacent iron cores 161, and the two adjacent main bodies 166 are respectively close to the N pole and the S pole, so that the two permanent magnets 143 of the upper and lower disc-type outer rotors 14 corresponding to each other can be respectively One branch bud 165 passes through the adjacent body 166 and returns to the other pole of the permanent magnet 143 to form two complete magnetic circuits up and down.

In particular, the overall thickness of the motor in this example is not more than 6 cm, but in fact the thickness is only about 5 cm, and the thickness of the outer disc rotor 14 is about 0.5 cm, so that the gap between the body 166 of the iron core 161 and the permanent magnet 143 is It is quite narrow and narrower than the thickness of the disk outer rotor 14, so that the part of the magnetic circuit passing through the air is very short; The slit 168 is also narrow, so that the magnetic field lines of the permanent magnet 143 will pass through the iron core 161 densely, and the magnetic resistance is thus greatly reduced. Of course, those skilled in the art can understand that, in order to form the above-mentioned corresponding magnetic circuit, the number of the aforementioned iron cores of the present invention must be a positive integer with a radially symmetrical distribution relative to the above-mentioned pivot axis, and the number is greater than twice the number of the above-mentioned permanent magnets and less than double.

Each of the above-mentioned iron cores 161 is respectively wound with an electric coil winding 163 between the two branch buds 165 for receiving an AC clock-type driving signal to magnetize the main body 166 of the above-mentioned iron core 161; as shown in FIG. When the magnetic pole of a permanent magnet 143 of the upper disc-type outer rotor is just about to pass through the corresponding end of the body 166, the end of the body 166 of the iron core 161 forms a magnetism opposite to the magnetic pole, so as to exert the attraction of opposite polarities. When the magnetic poles are gradually approached, the magnetism of the end of the iron core 161 begins to weaken and returns to zero, and then the phases change when the magnetic poles are far away, providing a thrust that repels with the same polarity; Periodic excitation, attracting the next magnetic pole again to continue to operate. Since the number of permanent magnets 143 is not equal to the number of iron cores 161 , in order to generate the maximum pushing torque, not only must the position of the permanent magnets 143 of the outer disc rotor be accurately obtained, but also each motor coil winding 163 must be provided with a phase difference Clocked drive signal. At the moment shown in FIG. 7 , the magnetic field lines of the permanent magnet above travel through the electric coil winding 163 and return from the lower branch bud 165 and the adjacent iron core body to form a complete magnetic circuit.

On the other hand, the magnetic field lines generated by the corresponding permanent magnets in the lower disk outer rotor do not pass through the electric coil windings 163 due to the magnetic repulsion with the electric coil windings 163, but directly pass through the lower branch buds 165 and the phases. The body 166 of the adjacent iron core 161 returns to the other magnetic pole of the permanent magnet 143 to form another complete magnetic circuit. With the two sets of magnetic circuits repelling each other, the operation of the lower disk outer rotor is further caused.

Therefore, referring to the rotor position sensing element 18 as shown in FIG. 8, it measures and outputs a position signal to the enabling controller 20, and the enabling controller 20 provides an alternating current according to the received position signal. The clock-type driving signal S1 is sent to the electric coil windings 163 of the railing stator 16, so that there is a uniform phase difference between the clock-type driving signals S1 of every two adjacent electric coil windings 163, and all the railings of the group have a uniform phase difference. The sum of the aforementioned phase differences between all adjacent motor coil windings 163 of the stator 16 is a non-zero integer multiple of 360 degrees. Therefore, each of the electric coil windings 163 will be driven by a clock-type driving signal that matches the rotational speed of the disk-type outer rotor 14 , and the clock-type driving signals received by the adjacent iron cores 161 respectively exist, such as 120 in this example. A phase difference of 10 degrees, so that after every three iron cores, the clock-driven signal received by the fourth iron core will be the same as that of the first iron core, and after surrounding nine iron cores, the phase difference in this example is The sum is 1080 degrees. In this example, the above-mentioned rotor position sensing element 18 is exemplified as a Hall element. Those with ordinary knowledge in the technical field of the present invention may select other suitable elements for simple transformation.

In this example, the rail-type stator 16 further includes a non-magnetically conductive stator base 164 to hold each iron core 161, and the non-magnetically conductive stator base 164 is further provided with a set of ball bearings at the upper and lower ends (Fig. Not shown), thereby allowing the pivot shaft 12 to pivot smoothly in the non-magnetically conductive stator base 164 . And let the disk-type outer rotor 14 and the rail-type stator 16 be relatively pivotably combined. Referring to FIG. 9 again, because the motor in this example is used as the actuating wheel of the electric bicycle, the outer disk rotor 14 can be directly coupled to the wheel frame 23 of the wheel, and the non-magnetically conductive stator base is further coupled to the electric bicycle. The front fork 21 of the bicycle is used to protect the railing-type stator from accidental collision or contact with external force, which may damage the iron core or the winding of the electric coil or short-circuit and burn it. Of course, even if the front fork is changed to a rear fork or a unilateral front fork, it will not hinder the implementation of the present invention.

In addition, when the motor is running, due to the relative rotation between the rail-type stator 16 and the disk-type outer rotor 14, the power-generating coil windings 167 disposed at the two branch buds 165 will cut the magnetic lines of force during the movement, so the power-generating coil windings During the rotation of the front wheels, the 167 will recover part of the kinetic energy and convert it into electrical energy, which will be output to, for example, headlights (not shown).

When the magnetic poles of the permanent magnets 143 of the outer disk rotor 14 of the outer disk motor 1 are located above the axial direction, the magnetic poles of the permanent magnets 143 of the outer disk rotor 14 are arranged in series on the base body in the manner of N-S, S-N, N-S . . . from left to right as shown in FIG. 7 . The magnetic poles of the permanent magnets 143 of the outer disk rotor 14 in the axial direction are oppositely arranged from left to right as N-S, S-N, and N-S. Since the electric coil winding 163 is driven by the clock-type driving signal S1 to form an induction magnetic pole with an S pole on the upper side and an N pole on the lower side, on the one hand, it is just different from the magnetic poles of the permanent magnets 143 of the upper disk-type outer rotor 14 that are close to each other. , together form a closed magnetic field line, the permanent magnet 143 is pulled by the iron core 161 to move along the tangential direction of the circle 121, that is, the disk outer rotor 14 is magnetically driven to rotate by the railing stator 16.

On the other hand, the magnetic poles of the lower disk outer rotor 14 form another set of magnetic field line loops, which further drive the outer rotor to rotate due to the attraction of different magnetic poles and the repulsion of the same magnetic poles. In this example, the same push/pull action will be generated every 120 degrees on the circumference of the circle 121, so that the above-mentioned outer disc motor 1 can generate three times the push/pull force in each phase. And after the permanent magnet 143 passes through the corresponding end of the main body 166 , the excitation clock-type driving signal will gradually change phases again, so that the disk-type outer rotor 14 continues to operate.

In this example, the ratio of the number of the aforementioned iron cores 161 to the number of the permanent magnets 143 is 3:2, that is, every three aforementioned iron cores 161 corresponds to two permanent magnets 143 respectively, and a total of three groups of such corresponding combinations are formed around the base 141 . And the shortest distance between the above-mentioned iron core 161 and the corresponding permanent magnet 143 is smaller than the thickness of the above-mentioned base 141; and the main body 166 of the branch-like iron core 161 is also close to the branch-bud portion 165 of the adjacent branch-like iron core 161, which is relatively The slits between the adjacent branch bud-shaped iron cores 161 are also narrow, so that the corresponding iron cores 161 and the permanent magnets 143 form a good magnetic flux circuit. The lower permanent magnet 143 also forms another good magnetic circuit, and is operated by magnetic thrust because of its repulsion with the upper magnetic circuit. Considering the introduction of the clocked driving signal, the permanent magnet 143 rotates with the rotor, and when the induced magnetic poles in the iron core 161 are commutated, the magnetic field lines of the permanent magnet 143 pass through the iron core 161, so that the hysteresis loss (Hysteresis losses), thereby reducing the heating of the magnetic conductor, and also reducing the consumption of electric energy, and the overall conversion efficiency of the motor is thus increased.

When the disk-type outer rotor 14 is pushed and rotated by the rail-type stator 16, the corresponding relationship between the iron core 161 and the permanent magnet 143 is dislocated and changed. A magnetic pole is attracted by a different magnetic pole. At this time, the rotor position sensing element 18 will sense the change of the position of the permanent magnet 143 of the disk outer rotor 14, and further output a position signal to the enabling controller 20. , prompting the enabling controller 20 to determine whether there is a rotational speed change of the outer disk rotor 14 according to the received position signal, and determine whether the frequency of the AC clock drive signal needs to be increased or decreased.

In this embodiment, in order to further reduce the distance of the air gap and to concentrate the magnetic lines of force of the permanent magnets 143 , each two oppositely opposite poles of the permanent magnets 143 are installed at positions where the magnetic poles of the permanent magnets 143 face the railing stator 16 , respectively. There is a magnetic focusing magnet 145, which is a flat cylindrical permanent magnet in this example, and each magnetic focusing magnet 145 attracts with the magnetic pole of the corresponding permanent magnet 143, and assumes the channel as the magnetic force line, further narrowing the magnetic field by the permanent magnet. The air gap between 145 and the iron core 161 reduces the magnetic resistance and improves the conversion efficiency. Of course, as can be easily understood by those skilled in the art, the magnetic concentrating magnet is not necessarily provided.

The bud-shaped iron core in the above embodiment is not limited to extending from one side of the main body, but also can be shown in the second preferred embodiment of the present invention as shown in FIGS. 10 to 13. On the one hand, the permanent magnet 143' and The gap between the adjacent permanent magnets 143' is narrowed, and at the same time, the distance between the permanent magnets 143' and the iron core body 166' arranged along the virtual circular tube 123' is reduced, so that the magnetic resistance between the rotor and the rail-type stator 16' is reduced. reduce. At each position where the magnetic poles of the permanent magnets 143' with opposite polarities and close to each other face the balustrade-type stator 16', a concentrating magnet 145' is respectively installed. In addition, the permanent magnets 143 ′ only need to be evenly arranged in pairs, not limited to 6, and the number of iron cores in the rail-type stator 16 ′ only needs to be in the range from one to one of the permanent magnets 143 ′. An integer between two times is sufficient. The key point is that the total phase difference between the above clocked driving signals is an integer multiple of 360 degrees, and the phase difference between every two adjacent coils is the same as each other and changes with the rotation speed.

In particular, in order to make the bud-shaped iron cores 161 ′ of the railing stator 16 ′ more balanced, the bud-shaped iron cores 161 ′ in this example extend from the cylindrical body 166 ′ toward the left and right sides by two each. The cylindrical branch buds 165' make the adjacent iron cores 161' close to the corresponding branch buds 165', and in this example, each branch bud 165' is provided with a generator coil winding 167', each branch bud-shaped iron core 161' is wound with an electric coil winding 163' between the two branch buds 165'. When the output of the formed motor is insufficient, a set of auxiliary rail-type stators and auxiliary disk-type outer rotors can be added along the coaxial direction of the pivot shaft under the disk-type outer rotor 14' as shown in Fig. 10, thereby increasing the overall Torque output.

Due to the above-mentioned configuration of the number of iron cores and coils and the structural design of the branch buds, a complete magnetic field line path of the permanent magnet can be provided, so that the magnetic resistance can be greatly reduced, and the rotational movement of the permanent magnet can periodically weaken the excitation of the iron core by the AC signal. The hysteresis phenomenon in the process reduces the heat generation and energy consumption caused by the hysteresis phenomenon, thereby enabling the motor disclosed in the present invention to have low calorific value and high energy conversion efficiency during operation, and achieve the above-mentioned advantages beyond the prior art. purpose of the invention.

The above descriptions are only preferred embodiments of the present invention, which cannot limit the scope of the present invention. Any simple equivalent changes and modifications made according to the claims and description of the present invention shall still belong to the present invention. covered by the patent.
