Detailed Description
The foregoing and other technical and other features, aspects and utilities of the present invention will be apparent from the following detailed description of the preferred embodiments, taken in conjunction with the accompanying drawings; further, in the embodiments, the same elements will be denoted by the same reference numerals.
In a preferred embodiment of the disc motor/generator with a stator of a rail type, please refer to and refer to fig. 3 to 6, an outer disc motor 1 has pivots 12 extending along axial direction, which is defined as the up-down direction along the drawing for the convenience of description, and two disc type outer rotors 14 disposed in parallel with each other, each disc type outer rotor 14 includes bases 141 and an even number of permanent magnets 143, which are exemplified by 6 permanent magnets 143 in this example, and the bases 141 in this example are circular disc-shaped and are perpendicularly fixed to the pivots 12 with their symmetrical centers.
The permanent magnets 143 are each embedded in the base 141 in a substantially flat curved arc shape in this example, and the two magnetic poles N, S of each permanent magnet 143 are not only disposed at the base 141, but also the two adjacent permanent magnets 143 are disposed in a manner such that two phases of N-pole are close or two phases of S-pole are close, as can be easily understood by those skilled in the art, even if the permanent magnets are modified to have other shapes such as horseshoe or rectangle, the implementation of the present invention is not hindered as long as the permanent magnets are disposed in the base 141 in the foregoing manner, and since the permanent magnets 143 themselves in this example are curved arc shapes, the curved arc shapes of the magnets are such that the respective magnets and the magnetic poles are uniformly arranged on circles 121 centered on the pivot 12, and the two disc outer rotors 14 are disposed in such a manner that the same magnetic poles of the permanent magnets 143 are opposite to each other.
The outer disk motor 1 further includes groups of stator bars 16, the group of stator bars 16 includes 9 branched bar-shaped iron cores 161 in this example, for the sake of illustration, the branched bar-shaped iron cores 161 are further divided into groups into a main body 166 disposed substantially parallel to the direction of the pivot 12 and at least two branched bar portions 165 extending from the main body 166 and substantially perpendicular to the main body 166, the branched bar portions 165 in this example extend only from the same side of the main body 166, so that the branched bar-shaped iron cores 161 in this example are similar to "pi" of the greek letter in side view, and each of the main body 166 in this example is 3.5 cm in length, and the iron cores 161 in this example are explained as being composed of a plurality of silicon steel sheets, thereby reducing eddy current and commonly receiving non-magnetic-conductive stator bases 164.
The bodies 166 of the iron cores 161 of are respectively arranged in parallel to each other along the axial direction, and are uniformly distributed at circular tubes 123 with the pivot 12 as the center, because the iron cores 161 are uniformly arranged, in this example, the included angle between the connecting line of the body 166 and the pivot 12 and the connecting line of the adjacent body 166 and the pivot 12 is 30 degrees, and the two poles of the body 166 of each iron core 161 are respectively close to the permanent magnets 143 corresponding to the two disc type outer rotors 14, because the number of the iron cores 161 in this example is 1.5 times of that of the permanent magnets 143, no matter the disc type outer rotors rotate to any position, a part of the permanent magnets 143 can just correspond to the bodies 166 of the two adjacent iron cores 161, and the two adjacent bodies 166 are respectively close to the N pole and the S pole, so that the two permanent magnets 143 corresponding to the disc type outer rotors 14 above and below can respectively return to the other pole of the permanent magnets 143 through the adjacent bodies 166 by branches 165 to form two complete magnetic loops.
In particular, as the thickness of the entire motor in this embodiment is not more than 6 cm, actually, the thickness is only about 5 cm, the thickness of the disc type outer rotor 14 is about 0.5 cm, so that the gap between the body 166 of the core 161 and the permanent magnet 143 is relatively narrow, and is narrower than the thickness of the disc type outer rotor 14, so that the portion of the magnetic circuit through which air passes is short, and the slits 168 between the body 166 of each core 161 and the branches 165 of the adjacent core 161 are also narrow, so that the magnetic lines of force of the permanent magnet 143 will pass through the core 161 densely, and the magnetic resistance is greatly reduced.
For each , electric coil windings 163 are respectively wound between two branch parts 165 of the iron core 161, and a clock type driving signal receiving alternating current is used for magnetizing a body 166 of the iron core 161, as shown in fig. 7, when the magnetic poles of permanent magnets 143 of the upper disc type outer rotor are just approaching to pass through the corresponding end part of the body 166, magnetism opposite to the magnetic poles is formed at the end part of the body 166 of the iron core 161 so as to exert attraction force with opposite polarities, and when the magnetic poles gradually approach, the end magnetism of the iron core 161 begins to weaken and return to zero, then the magnetic poles are far away and phase-changed so as to provide thrust force with same polarity repulsion, and excitation of the next period is not carried out until the magnetic poles of the sub approach again, and the sub magnetic poles are attracted again to continue to operate, because the number of the permanent magnets 143 is not equal to the number of the iron core 161, the maximum pushing torque is generated, not only the position of the permanent magnets 143 of the disc type outer rotor has to be accurately obtained, but also the electric coil windings 163 with phase difference are provided for each , and the electric coil windings 163 above are instantaneously formed by the adjacent magnetic field lines and the magnetic poles are returned to the adjacent magnetic field lines of.
On the other hand, the magnetic lines of force generated by the corresponding permanent magnets in the lower disk outer rotor are repelled from the magnetic field of the electric coil winding 163, and therefore, the magnetic lines of force do not pass through the electric coil winding 163, but directly pass through the lower branch bud 165 and the body 166 of the adjacent iron core 161, and return to the other magnetic pole of the permanent magnet 143 to form another complete magnetic loop, and the two sets of magnetic loops repel each other, so that the step causes the lower disk outer rotor to operate.
, referring to the rotor position sensing device 18 shown in fig. 8, measure and output position signals to the enable controller 20, and the enable controller 20 provides ac clock-type driving signals S1 to the electric coil windings 163 of the rail stator 16 according to the received position signals, so that uniform phase differences exist between the clock-type driving signals S1 of each two adjacent electric coil windings 163, and the sum of the phase differences among all the adjacent electric coil windings 163 of the set of rail stator 16 is a non-zero integer multiple of 360 degrees, therefore, each electric coil winding 163 is driven by the clock-type driving signal matching the rotation speed of the disc-type outer rotor 14, and a phase difference of 120 degrees exists between the clock-type driving signals received by the adjacent iron cores 161, so that after every three iron cores are separated, the fourth iron core receives the same clock-type driving signal as the iron core, and after the nine iron cores are surrounded, the sum of the phase differences in the 1080 degree rotor position sensing device is released in the field of the present invention, and the hall-based on the knowledge of the present invention can be easily implemented.
In this example, the baluns stator 16 further includes non-magnetic conductive stator bases 164 for holding each iron core 161, and the non-magnetic conductive stator bases 164 are further provided with sets of ball bearings (not shown) at upper and lower ends thereof, respectively, so that the pivot 12 can be pivoted smoothly in the non-magnetic conductive stator bases 164. the disc type outer rotor 14 and the baluns stator 16 can be combined in a relatively pivoting manner, referring again to fig. 9, since the motor in this example is used as an actuating wheel of the electric bicycle, the disc type outer rotor 14 can be directly coupled to the rim 23 of the wheel, and the non-magnetic conductive stator bases are further coupled to the front fork 21 of the electric bicycle to protect the baluns from accidental collision or contact of the iron core or the electric coil winding, and of course, the front fork can be changed into a rear fork, or into a single-side front fork.
In addition, when the motor is running, due to the relative rotation between the rail stator 16 and the disc type outer rotor 14, the power generation coil winding 167 arranged at the two branch bud portions 165 can cut magnetic lines of force during the movement, so that the power generation coil winding 167 can recover part of kinetic energy and convert the kinetic energy into electric energy during the rotation of the front wheel, and output the electric energy to a vehicle lamp (not shown) for use.
When the magnetic poles of the permanent magnets 143 of the outer disk rotor 14 of the outer disk motor 1 located axially above are arranged in series in the matrix in a butt joint manner 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 located axially below are arranged in the N-S, S-N, N-S manner from left to right in an opposed manner, and the electric coil winding 163 is driven by the clock type driving signal S1 to form an induction magnetic pole having an S pole at the top and an N pole at the bottom, and is just different from the magnetic poles of the permanent magnets 143 of the upper outer disk rotor 14 close to each other, so as to form closed magnetic lines of force, and the permanent magnets 143 are pulled by the iron core 161 to move along the tangential direction of the circle 121, that is, the outer disk rotor 14 is driven to rotate by the magnetic force of the rail type.
On the other hand, the magnetic poles of the lower disk outer rotor 14 form another sets of magnetic force lines, which are attracted by different magnetic poles and repelled by the same magnetic poles to drive the outer rotor to rotate in steps, but in this example, the same push/pull action is generated at every 120 degrees on the circumference of the circle 121, so that three times of push/pull force can be generated in each phase of the outer disk motor 1, and after the permanent magnets 143 pass through the corresponding ends of the main body 166, the excited clock type driving signals are gradually changed in phase to make the disk outer rotor 14 operate continuously.
In this embodiment, the ratio of the number of the iron cores 161 to the number of the permanent magnets 143 is 3: 2, that is, three iron cores 161 correspond to two permanent magnets 143, 3 sets of corresponding combinations are formed around the base 141 , the shortest distance between the iron core 161 and the corresponding permanent magnet 143 is smaller than the thickness of the base 141, the main body 166 of the branched iron core 161 is close to the branched portion 165 of the adjacent branched iron core 161, the slits between the adjacent branched iron cores 161 are also narrow, so that the corresponding iron core 161 and the corresponding permanent magnet 143 form a good magnetic flux loop, the lower permanent magnet 143 also forms another good magnetic loops, and is operated by magnetic thrust due to repulsion with the upper magnetic loop, and considering the introduction of the clock type driving signal, the permanent magnet 143 rotates with the rotor, so that magnetic lines of force of the permanent magnet 143 pass through the iron core 161 when the induction poles in the iron core 161 are just changed, so that Hysteresis losses (hysteris) are reduced, and further, the consumption of the magnetic body is reduced, and the overall conversion efficiency of the motor is increased.
When the disc outer rotor 14 is driven by the stator 16 to rotate, the corresponding relationship between the iron core 161 and the permanent magnet 143 is changed, the same pole repulsion force of the original magnetic pole is gradually changed by the rotation of the rotor, and the attraction force of the different magnetic pole is applied to the secondary magnetic pole, at this time, the rotor position sensing element 18 senses the change of the position of the permanent magnet 143 of the disc outer rotor 14, and further steps output position signals to the enable controller 20, so that the enable controller 20 can determine whether the rotation speed of the disc outer rotor 14 is changed according to the received position signals, and determine whether the frequency of the ac clock type driving signal needs to be increased or decreased.
In this embodiment, to further reduce the air gap distance and concentrate the magnetic flux of the permanent magnets 143, flux gathering magnets 145, in this case flat cylindrical permanent magnets, are installed at each two opposite poles near the pole facing the stator 16 of the permanent magnets 143, each flux gathering magnet 145 attracts the corresponding pole of the permanent magnet 143 and serves as a passage for the magnetic flux, and narrows the air gap between the permanent magnet 145 and the core 161 to lower the magnetic resistance and improve the conversion efficiency.
The branched core in the above embodiment is not limited to one side extended from the body, but as shown in fig. 10 to 13 as a second preferred embodiment of the present invention, is to narrow the gap between the permanent magnet 143 'and the adjacent permanent magnet 143', and at the same time, to reduce the distance between the permanent magnet 143 'and the core body 166' arranged along the virtual circular tube 123 ', so that the magnetic resistance between the rotor and the stator 16' is reduced, magnetism collecting magnets 145 'are respectively installed at positions where the magnetic poles of the two opposite poles close to the permanent magnet 143' face the stator 16 ', and further, the permanent magnets 143' only need to be uniformly arranged in pairs, not limited to 6, and the number of cores in the stator 16 'only needs to be an integer between times and twice the number of the permanent magnets 143', and it is critical that the total phase difference between the driving signals of the above-mentioned types is an integer multiple of 360 degrees, and the phase difference between the adjacent coils is the same and is changed with the rotation speed.
In particular, in order to make the branch-bud-shaped iron cores 161 'of the stator 16' more balanced in the left-right direction, the branch-bud-shaped iron cores 161 'in this example are extended with two cylindrical branch-bud portions 165' from the cylindrical main body 166 'toward the left and right sides, so that the adjacent iron cores 161' are close to the corresponding branch-bud portions 165 ', and in this example, generator coil windings 167' are provided for every branch-bud portions 165 ', and each branch-bud-shaped iron core 161' is wound with electric coil windings 163 'between the two branch-bud portions 165', and when the motor output simply constituted by two disc-type outer rotors 14 'and sets of the branch-type stators is insufficient, it is possible to increase sets of auxiliary-type stator bars and auxiliary-type outer rotor bars along the coaxial direction of the pivot shaft under the disc-type outer rotor 14' below fig. 10, thereby increasing the overall torque output.
The number of the iron core-coils and the structural design of the branch bud part can provide a complete magnetic line of force access for the permanent magnet, so that the magnetic resistance is greatly reduced, the rotation movement of the permanent magnet can periodically weaken the hysteresis phenomenon of the iron core in the process of being excited by an alternating current signal, and the heat generation and energy loss caused by the hysteresis phenomenon are reduced, so that the motor disclosed by the invention has low heat generation and high energy conversion efficiency in the running process, and the aim of the invention exceeding the prior art is fulfilled.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
