[Prior Art] The transmission is used for power transmission. In addition to relaying and transmitting power, it has the function of decelerating or increasing the speed of the power source. The gearbox of the conventional automobile engine has a mechanical gearbox and Hydraulic gearbox. For electric vehicles or hybrid vehicles, there are magnetic transmissions. The technology of the variable speed motor can be found in the US 3,980,937 rFractional Horsepower Gear Motor j > announced on September 14, 1976. ^ The output power of the motor passes through the mechanical gear set to achieve the torque conversion and shifting effect. In addition, US Patent No. 5,825,111 issued on October 20, 1998, "Single-phase induction motomoto 4/6 pole common winding connection with magnetic motive force symmetrically distributed" and the United States No. 7,598,648 announced on October 30, 2009 The patent "2/6 pole single-directional induction motor having shared windings" discloses the purpose of achieving shifting by changing the number of poles of the induction motor stator. The related technology of the magnetic transmission can also be found in the article "A Novel High-Performance Magnetic Gear" published by K. Atallah and D. Howe in the Journal of the International Society of Electrical and Electronics Engineers in July 2001.

Magnetics, Vol. 37, No. 4, July, 2001). 201131947 The aforementioned mechanical transmission has the disadvantages of high noise and heavy weight, while the general magnetic transmission can reduce vibration and noise, but it cannot reduce the weight. In addition, in the application of electric ruts, 'the need for electric motors to match different driving torques and driving speeds' must also take into account the requirements of high-efficiency operation. Therefore, the motor and the shifting cymbal are often matched. Under such heart ingredients, the motor and Wei Difficult body dynamism is usually not easy to increase (due to the total weight of the motor and the transmission). SUMMARY OF THE INVENTION Based on the above problems, the proposed magnetic shifting composition is easy to integrate with an electric motor (such as an electric motor) or a generator (10) and has a light weight characteristic, so that the driving power density can be improved. According to the real example, a magnetic shifting composition includes a rotor, a stator, and a magnetically permeable member. The rotor and the stator are sleeved, and the rotor has a plurality of magnetic poles and has r pole pairs. The stator has a plurality of magnetic poles and a number of pole pairs. The magnetically conductive element is located between the rotor and the stator and has a magnetizer. When the magnetically permeable element is actuated, the magnetically permeable element selectively causes the ΡΝ1 or ρΝ2 to act as the stator and the stator. Between ΡΝ 1-3 $ R+ST1 $ ρνι+3, ΡΝ 2-3 ^ R+STl g ΡΝ2+3. According to an embodiment of the magnetically conductive element, the magnetic conductive element comprises a first ring and a second ring, the first ring and the second ring are axially connected, the first ring has PN1 magnetic sub-blocks, and the second ring has PN2 The magnetically permeable sub-blocks' selectively bias the first or second ring between the rotor and the stator when the magnetically permeable element is axially actuated. According to a first embodiment of the magnetically permeable element, the magnetic conductive element comprises a first ring and a first-thickness-first ring system located radially outward of the second ring (four) and the first ring and the second ring are disposed at " 5 201131947 Between the stator and the rotor, when the magnetically conductive element is scaled, the first ring and the second ring are relatively displaced between the first position and the second position 'When the first ring and the second ring are in the first position The magnetically conductive element has PN1 of the magnetizer, and when the first ring and the second ring are in the second position, the magnetic conductive element has |^2 of the magnetizers. According to another-reality, the stator comprises a multi-penetration _ and a pole-number modulation circuit, wherein the induction coil is galvanically mixed when conducting, and the pole-number circuit selectively switches the induction coil to the ST1 pole pair and one ST2 between the pole pairs. Among them, PN2-3 S R+ST2 $ PN2+3. According to yet another embodiment, the magnetic shifting composition comprises a rotor, a stator and a magnetically permeable element. The rotor has a plurality of magnetic poles, and the magnetic poles of the rotor have R pole pairs. The stator and the rotor are sleeved on the same shaft, and the dice have a plurality of magnetic poles, and the magnetic poles of the stator have ST1 pole pairs. The magnetic conductive element is disposed between the rotor and the stator and has pN1 magnetic conductive sub-blocks, and the pN1 magnetic conductive sub-blocks are correspondingly disposed between the rotor and the stator, wherein ρΝ1·3 g r+sti S PN1+3. The magnetic conductive element is disposed between the stator and the rotor, and the design of the magnetic flux element can selectively change the number of the magnetic conductive bodies (that is, the number of magnetic gaps also changes), so that different gear ratios can be generated between the stator and the rotor. (The stator speed is higher than the rotor speed). Secondly, in another embodiment, the magnetic logarithm of the stator also has a convertible design. Thus, the magnetic conducting component, the stator and the rotor can be used for the purpose of generating different gear ratios. Designed as a hollow ring, the entire magnetic shifting composition is relatively small in size and weight, and can be easily integrated with an electric motor for high drive power density (Watt/kg, W/Kg or watt/volume, W/m3). 201131947 Characteristics and implementation of this proposal 'The chart and implementation of the ship's chart are as follows. [Embodiment] Please refer to "Fig. 2" and "2nd drawing" at the same time, which are respectively a three-dimensional structure and an exploded view according to the present proposal-embodiment. As can be seen in the figure, the magnetic shifting composition includes a rotor 2, a stator 3, and a magnetically permeable element 4 (also referred to as a magnetically permeable element). The magnetic shifting composition can be adapted to be integrated with an electric motor (such as an electric motor) or a generator. For example, if it is integrated with the electric motor of the electric vehicle and the motor is driven by the motor-driven drive to the magnetic shifting component, the magnetic shifting component can generate rotational power from the rotor, and the gear ratio of the motor drive is appropriately (four) misaligned. 'Magnetic shifting composition can output different power (power = drive out torque X speed). Since the magnetic shifting group includes the functions of the electric motor and the transmission, the overall volume and weight are low, and the high dynamic power density can be achieved. The drive power here can be, but is not limited to, output power divided by volume, or output power divided by, heavy star (ie (output torque χ speed) / volume, or (round torque x speed) / weight). _ From 'If the magnetic shifting group is used for the electric mechanical towel, the rotary power can be received by the rotor 2〇, and the electric power generated by the magnetic field cutting can be outputted by the stator 30 (detailed later). After the voltage regulator circuit is output. Since the magnetic speed change composition can be controlled by the gear ratio, when the input rotary power has a large variation or the better H feed efficiency is obtained, it can be achieved by controlling the speed ratio of the magnetic shift. Continuing to refer to "Fig. 1" and "Fig. 2", the stator 30 may be a fixed magnet or an induction magnet (or an electromagnet). In the present embodiment, an induction magnet is exemplified. The inner ring of the fixed t 7 201131947 30 is provided with a plurality of bumps 32a, 32b. Each of the bumps 32a, 32b is wound with an induction coil (described in detail later), and when the induction coil is energized, a magnetic pole can be formed. Taking the embodiment of the drawing as an example, the stator 30 has 48 bumps 32a, 32b, and each of the bumps 32a, 32b is energized to form a pair of magnetic poles. In this example, there are four phases (4 phases), and the parent phase has 12 pole pairs (20 Pole Pairs). Please also refer to "3", which is a stator 3 according to an embodiment of the present proposal. Schematic diagram of the magnetic logarithm. It can be seen in the figure that the adjacent magnetic poles have opposite polarities (magnetic north pole N and magnetic south pole s). Two adjacent magnetic poles of opposite polarity are a magnetic pair (for example, S1 of the figure, N1 is a magnetic pair. It can be seen from the figure that there are 12 pole pairs in total, and the pole logarithm is only one implementation. This proposal does not The number of magnetic pairs is limited to ST1 poles. The rotor 20 may be a fixed magnet or an induction magnet. In the present embodiment, the rotor 2 is described by taking a fixed magnet as an example. The rotor 20 has a plurality of magnetic poles and has r In this embodiment, the rotor 20 is exemplified by having 20 pole pairs. The stator and the rotor 20 are coaxially arranged (coaxially sleeved), and in this embodiment, the rotor 2 is disposed on the stator 30. The radial inner side is not limited thereto. The stator 3〇 may be disposed on the radially inner side of the rotor 20, and the object of the present invention can still be achieved. Secondly, the direction of the magnetic pole (magnetic field line) of the rotor 20 is directed toward the stator. The direction of the magnetic pole (magnetic line) of the 3 。. The magnetic conductive element 40 may be laminated steel, and the material thereof may be a Soft Magnetic Composite (SMC) to reduce eddy current (Eddy)

Current) and iron loss. Referring again to "Fig. 1" and "Fig. 2", the magnetically permeable element 40 includes a first ring 42 and a second ring 44. The first ring 42 is located radially outward of the second ring 44, and the first 201131947 裱 and the second ring 44 are disposed between the stator 3〇 and the rotor 2〇. The first ring & second ring 44 series can be in contact with each other or at a distance (the system is separated by a gap). The first ring 42 has a plurality of magnetic sub-blocks 42(), 422. The second ring 44 also has a magnetically permeable sub-block, 442. When the first ring & is located on the outer side of the second ring 44, the sub-blocks 422, 44, 442 can form a plurality of magnetizers (described in detail later). When the first 42 or/and the second ring 44 are actuated, the two can be relatively moved (relatively rotated) between the first position and the second position, and the number of the magnetizers also changes accordingly. As explained below. Please refer to "Figure 4A". Fig. 4A is a schematic cross-sectional view showing the first embodiment of the magnetic flux 7L according to the present invention. The cross-sectional view is a cross-sectional view in which the -% 42 of the "Fig. 2" is placed on the radially outer side of the second ring 44, and the plane perpendicular to the axial direction is the cut surface. In order to facilitate the explanation of the relative rotation of the first ring 42 and the second ring material, the arcs labeled as 429 and 449 in "Fig. 4A" are further enlarged in "Fig. 4B". The arc angles of the arc segments 429, 449 are 45 degrees, so that the entire first ring 42 and the second ring 44 have a total of 8 arc segments 429, 449. The "Fig. 4B" is a partially enlarged cross-sectional view showing a state in which the first ring 42 and the second ring 44 are at the first position. Fig. 4C is a partially enlarged cross-sectional view showing the state in which the first ring 42 and the second ring 44 are in the second position. As can be seen from "Fig. 4B", the magnetically permeable sub-block 420 of the first ring 42 and the magnetically permeable sub-block 440 of the first ring 44 are connected (or overlapped) and the magnetizer 46 is formed to be similarly The magnetically permeable sub-block 422 of the ring 42 is connected to the magnetically permeable sub-block 442 of the second ring 44 and forms a magnetizer 46b. There are three magnetic gaps 48a, 48b, 48c of 201131947 between the magnets 46a, 46b. Since the entire first ring 42 and the second ring 44 have the same eight arc segments 429, 449', the entire first ring 42 and the second ring 44 will have 24 magnetic gaps 48a, 48b, 48c (3x8=24, That is, there are 24 magnetizers 46a, 46b). Continued, refer to Fig. 4C, which is a partially enlarged cross-sectional view showing the state in which the first ring 42 and the second ring 44 are at the second position. The magnetically permeable sub-block 420 of the first ring 42 and the magnetically permeable sub-block 440 of the second ring 44 are connected to each other and form a magnetizer 46a. Similarly, the magnetic permeable sub-block 422 of the first ring 42 is connected to the magnetic permeable sub-block 442 of the second ring 44 and forms a magnetizer 46b. As can be seen, the arc segments 429, 449 have four magnetic gaps 48a, 48b, 48c, 48d and also have four magnets 46a, 46b. Therefore, there will be 32 (4x8=32) magnetic gaps 48a, 48b, 48c, 48d throughout the first ring 42 and the second ring 44. The foregoing magnetically conductive sub-blocks 420, 440 are in a connected state, and the distances are similar, and not only the state of contact, but the magnetic proximity of the magnetically conductive sub-blocks 42〇, 44〇 may not be in contact but overlap in the radial direction. Alternatively, the magnetically permeable sub-blocks 420, 440 are not in contact and have a pitch in the radial or circumferential direction. In the meantime, if the magnetic sub-blocks are not in contact with each other, the magnetic sub-blocks 420, 440 are separated by two distances, one of which is a radial distance, and the other is a distance in the circumferential direction of the mouth. As far as the distance of the control is concerned, it is experimentally found that if the distance between the white and the white is within 5 mm (mm), the effect of forming a single magnetizer 4 can be achieved. Of course, this distance is also related to the strength of the magnetic field lines of the stator 30. If the strength of the magnetic lines is stronger, the distance can be larger. That is to say, this radial distance changes depending on the size of the magnetic shifting composition itself and the strength of the magnetic field lines. The distance (arc length) in the circumferential direction of the latter can also be expressed as the angle between the boundary of the magneto-optical block 4 and the 201131947 440 boundary corresponding to the center of the circle (the center of the stator). For example, taking the example of FIG. 4B, the magnetic sub-block 420 The angle between the left side of the magnetic conductive sub-block 440 and the right side of the magnetically conductive sub-block 440. In order to further define this angle or arc length, the space formed by the distance between the left side of the magnetic sub-block 420 and the right side of the magnetic sub-block 440 is defined as an air gap. Since the magnetic shifting composition is in operation, each magnetic gap 48a, 48b, 48c ("4B") generates a magnetic pole (hereinafter referred to as a magnetic gap magnetic pole), and has a gas between the magnetic conductive sub-blocks 42, 44 When the seam is sewn, the gas seam also has a magnetic pole (hereinafter referred to as an air gap magnetic pole), and the magnetic field strength of the air gap magnetic pole is preferably smaller than that of the gas to form the front magnet 46a. Twenty percent (2 〇〇 / 〇) of the magnetic field strength of the gap magnetic pole. The arc length or the corner angle obtained by retracting the magnetic field strength of the air gap magnetic pole is a preferred circumferential direction pitch. The material of the magneto-optical block 42 〇, like 44 〇, 442 can be selected from any magnetically permeable material such as an iron-based material or soft iron. When the relative motion of the first ring α and the second ring is driven by the ejector and the electromagnetic mode drive 1 is driven, the first ring 42 or the second ring 44 may be separately driven, or the first ring and the first ring The 44th simultaneous driving is as long as the relative position of the first garment and the first portion 44 can be displaced between the first position and the second position. The position of the "figure map" is: "=ΓΓ- position (such as "Zhen Yan 49 Shu Zeng -" position of the younger brother C"), when the first % 42 and the second core 44 are in the first position called the continent Chest-shirt shoulder, when the first - ring 42 and 疋 4 cookware = one (the following set 'magnetic _ has 32 (-) - lead: = bit Γ Ϊ - -Ϊ 201131947 magnetic component 40 by the first The design of the relative movement of the ring 42 and the second ring 44 allows the magnetically permeable member 40 to selectively connect the PN1 or PN2 magnetizers 46a, 46b between the rotor 20 and the stator 3〇. By pN1 or For example, if the pN2 magnetizers 4 are mixed with the magnetic field of the mosquito 3Q of the rotor 2G, an increase/deceleration (shift) effect can be produced. The increase/decrease ratio can be obtained by the following formula (1): \mp + kn\ ............................................... ............................... Where G is the gear ratio (ie, the ratio of increase/deceleration), m, k is the harmonic The harmonics series 'p is the pole pair of the rotor 20, n is the number of the magnets 4, such as the number of steel Pieces. The main harmonic (filndamemal Μ·-) In the state of 'm=-k=l' and in the present embodiment, the rotor 2〇 The pole pair is 2 〇. Taking the first ring 42 and the second ring 44 at the first position as an example, the number of the magnets 4, for example, the number of the willows, is nested in the above formula, and ch1x2())/(1x24_1x2( )) = 5, the rotation speed of the mosquito is 5α than the rotation speed of the upper rotor. For example, if the first ring and the second ring 44 are located at the second position, the number of the magnets 46a, 46b is 32, and the formula of the above formula is obtained, and G=(ix2〇)/(i x32-lx20)= 1.6 'that is, the rotation speed of the stator 3 turns is i ^ than the rotation speed of the upper rotor 2 turns. From this, it can be seen that the magnetic shifting composition has the effect of shifting by the proper arrangement and design of the magnetic conducting element 40, the stator 3〇 and the rotor 2〇. Secondly, in order to improve the shift speed of the stator 30, the number of pole pairs R of the stator 30, the number of pole pairs R of the rotor 20, and the number of the magnetizers 46a and 46b of the magnetic conducting element 4〇 are maintained in the following relationship. The stable gear ratio and driving force will be obtained: 12 201131947 .... (2) PNl-3 ^ R+ST1 ^ PN1+3 PN2-3 ^ R+ST1 ^ PN2+3 — ....... ................................... Using this embodiment as an example, magnetic conduction When element 40 is in the second position, it satisfies equation (3) PN2_3 $ R+ST1 $ PN2+3. When the magnetic conductive element 4 is located at the first position, although the formula (2) ΡΝ 1-3 $ R+ST1 $ PN1+3 is not satisfied, it is still a variable speed requirement. In the present embodiment, if both equations (2) and (3) are to be satisfied at the same time, the design of the magnetic permeable sub-blocks 420, 422, 440, 442 of the magnetically permeable element 40 can be modified to make it full.

The foot type (2) may be, for example, if ST1 is 12, and pN1 and pN2 are % and 29, respectively, that the above formulas (2) and (3) are satisfied at the same time. In this embodiment, if the design of the magnetic conductive element 4〇 is not changed, and the formula (2) and the formula (3) are to be satisfied at the same time (however, the formula (3) needs to be slightly changed, and the details are described later), then " Embodiments of the stator 30 of Figures 5a and 5B. Fig. 5A is a winding diagram of another embodiment of the stator 30 of the magnetic shifting composition according to the present proposal. Fig. 5b is a schematic view showing the operation of another embodiment of the stator 30 of Fig. 5A. It can be seen from the figure that another embodiment of the stator 3 includes a plurality of induction coils 3 4 34b, 34c, 34d and a pole number modulation circuit 36. The induction coils 34a, 3B, 34c, 34d are wound around the bumps 32a, 32b, respectively. In "5A" and "5B", only the induction coils 34a, 34b, 34c, 34d of three magnetic pole pairs (Nl, N2, N3, Sl, S2, S3) are drawn but the stator 3 is not shown. 〇 only contains induction coils Ma, 3牝, 3, such as 3牝. The pole number modulation circuit 36 includes two switching switches 36A, 362. When the changeover switch 36A, 362 is in the state of "Fig. 5A" and the power is supplied, the magnetic pole formed by each of the induction coils 34a, 34b, 3, for example, 34d is the polarity as shown in "Fig. 3".

When the changeover switches 360, 362 are in the state of "Fig. 5B" and the power is supplied, the induction coils 34c, 34d which originally formed N1 and S3 are turned into the power supply in reverse, so that the magnetic poles formed are opposite (i.e., N1 is changed). For magnetic south pole, S3 becomes magnetic north pole), please refer to "Figure 6", which is a schematic diagram of the pole-to-number switching of "5A" and "5B". As can be seen from the figure, the dotted line indicates the polarity of the magnetic pole formed when the switch 36 〇 and 362 are located in the "5B". In the figure, Ni, N4, and N7 N10 are magnetic north poles in "5A", and S3, S6, S9, and S12 are magnetic south poles in "5A". At this time, the stator 30 has a total of 12 (hereinafter referred to as ST1) pole logarithm (ie Nl, Sl, N2, S3...N12, S12) 'But in "5B", because the switch 360, 362 and the clever setting of the circuit 'make Nl, N4, N7 When N10 is energized, it becomes a magnetic south pole, and S3, S6, S9, and S12 become magnetic north poles, and the rest remains unchanged. Therefore, the stator 30 has a total of four (hereinafter referred to as ST2) pole pairs (such as a dotted line frame, S1,, N2,, S2,, N3', S3', N4', S4'). In other words, when the induction coils 34a, 34b, 34c, 34d are switched to the ST1 pole pairs, the polarities (magnetic polarities) of the adjacent induction coils 34a, 34b, 34c, 34d are opposite 'When the induction coils 34a, 34b When 34c, 34d are switched to ST2 pole pairs, the induction coils 34a, 34b, 34c, 34d are grouped into a plurality of coil groups 35a, 35b, and the polarities of adjacent coil groups 35a, 35b are opposite. In this embodiment, each coil set 35a, 35b includes three sequentially adjacent induction coils 34a, 34b, 34c, 34d. Here, the adjacent adjacent systems are connected, for example, S1, N1, and S2 in "Fig. 5B" are sequentially adjacent induction coils 34a, 34b, 34c, 34d. In summary, the stator 30 can selectively switch the 201131947 induction coils Ma, Mb, Mc, 3 by one (ST1) pole pairs and * steps 2 poles by the pole number modulation circuit 36. By integrating the stator 3〇 embodiment of "5A" with the number of magnetisms of the magnetic conducting element, the Wei ratio (stator revolution: rotor speed) of the following table can be obtained, and the above formula (2) is satisfied. The following formula (4).

Therefore, the magnetic conductive element 5 can be changed by the appropriate design and control, and the speed ratio can be changed. The torque it transmits. Similarly, a plurality of annular (cylindrical) magnetically conductive rings (i.e., the first rings 42, 52, etc.) are radially stacked from the magnetic conductive elements 40 and 50 of the above-mentioned "Ath 4A" and "7A". The number of 'magnetic rings' can be changed according to the actual design requirements, that is, there can be a combination of three or five magnetic rings, but it is not limited to this number. The size, arrangement and number of the magnetic sub-blocks in the magnetically permeable ring can also be appropriately designed to produce different magnetic gaps in 201131947, thereby obtaining the desired ratio of variables.
