Description of the Invention: TECHNICAL FIELD The present invention relates to a motor, and more particularly to a motor and an electronic device using the same. [Prior Art] Due to the continuous use of fossil fuels, the emission of exhaust gas is increasing, making the greenhouse effect of the earth more and more obvious, and causing global climate anomalies. Therefore, many manufacturers have gradually developed alternative energy sources (for example) Electric power) Instead of petrochemical fuel electric vehicles, such as electric vehicles, electric motors, electric bicycles, etc., these will become the most commonly used vehicles in the future - 〇 electric vehicles use electric energy to drive the motor, which in turn drives the tires Rotate to achieve the purpose of movement, therefore, the choice of motor is a very important consideration. Conventional permanent magnet motors, whether brush motors or brushless motors, mostly use a radial flux structure or an axial flux structure. Please refer to FIG. 1A, which is a schematic structural view of a conventional radial flux motor la. Radial flux means that the direction in which the stator coils of the motor generate magnetic lines is perpendicular to the axis of the motor. Since the magnet has a magnet and a large amount of magnetic conductive material inside the radial flux motor, the magnetic circuit design between the magnet and the magnetic conductive material is limited by the structure of the rotor silicon steel sheet, and therefore, there are often Magnetic flux leakage occurs, which limits the torque density of the motor and does not provide a large torque output. Furthermore, as shown in FIG. 1B, it is a schematic structural view of a conventional axial flux motor 201203794 lb. The axial flux means that the direction of the magnetic lines of force is parallel to the axial direction of the motor. The axis uses the magnetically permeable material of ', so the phenomenon of magnetic entanglement is two: 疋, which is a flattened structure designed to rotate, but it is prone to yaw, resulting in shortened motor shaft and bearing life. ^Externally, another kind of permanent magnet motor has a transverse magnetic flux structure. The motor of the magnetic flux can realize a three-pass structure in the design of the crucible. The three-dimensional flux motor has the advantages of higher torque density and less magnetic leakage. It is suitable for low-speed, south-torque electric carrier. ❿ Refer to FIG. 1C, which is a schematic diagram of the path of the single-phase element of the transverse flux motor and the magnetic lines of the rotor unit. The direction of the arrow A is shown as the path of the magnetic lines of force. The transverse flux motor includes a certain subunit 1 and a rotor unit 2. Stator unit! The rotor core unit 2 includes a rotor core η and a dihydrate magnet 22, including: a stator core; The coil 12 is disposed between the two stator cores n. Further, the rotor core 21 is disposed opposite to the stator core 1丨, and the two permanent magnets 22 are respectively disposed between the two stator cores u and the two rotor cores and u. However, in order to realize the three-dimensional magnetic flux structure of the transverse flux motor, a permanent magnet 22 must be provided between the stator core and the rotor core 14 to guide the magnetic lines of force so that the motor has a three-dimensional magnetic flux structure. However, when the coil 12 of the stator core 11 is not driven, the magnetic force of the magnet 22 will interfere with the magnetic flux of the adjacent subunit U and the rotor unit 12, so that the overall efficiency of the motor is lowered. In addition, such a design also increases the size and weight of the motor. Therefore, how to provide a motor and an electronic device can avoid the magnetic leakage of the 201203794 image and improve the motor efficiency, and can reduce the size and weight of the motor, which has become one of the important topics.

The rotor unit 32 has at least two rotor cores 321 and at least one magnetic element 322. Here, the rotor unit 32 has a plurality of rotor cores 321 and a plurality of magnetic elements 322, and each of the magnetic elements 322 is disposed between the two rotor cores 321 as an example. Further, the magnetic element 322 is looped on the magnetic conductive element 313. The rotor unit 32 may further have two second supporting members 323. The second supporting member 323 is provided for fixing the rotor core 321 and the magnetic member 322, and is disposed at the outer edge of the stator core 311 of the stator unit 31, so that the two rotor cores 321 sandwich a magnetic member 322. However, in order to clearly illustrate the relative position of the rotor core 321 and the magnetic member 322, FIG. 2B does not show the second support member 323. Further, the rotor cores 321 are disposed opposite to the stator core 311, respectively, and the magnetic member 322 is disposed opposite to the coil 312. The rotor core 321 may also include a magnetically permeable material. The magnetically permeable material can be, for example, a soft magnetic composite material. Further, the magnetic member 322 is a permanent magnet. In particular, in order to clarify the connection relationship between the stator unit 31, the rotor unit 32, and the shaft center 33, FIG. 2A shows the shaft center 33. However, the shaft center 33 is not included in the rotor unit 32. 2C and 2D, the structure of the stator unit 31 and the rotor unit 32 of the motor 3 and its three-dimensional magnetic flux are more clearly shown. 2C is a front view of FIG. 2B, and FIG. 2D is a cross-sectional view of the line C-C in FIG. 2C. The direction of the arrow B in Fig. 2D shows the magnetic paths of the rotor core 321, the magnetic element 322, and the magnetic conductive element 313 when the coil 312 of the stator unit 31 is not driven. As shown in FIG. 2D, at this time, the magnetic flux of the motor 3 is passed through the rotor core 321, the magnetic element 322, and then through the rotor core 321, and then guided to the rotor core 321 by the magnetic conductive element 313. Therefore, the magnetic force of the magnetic member 322 will not interfere with the three-dimensional magnetic circuit of the adjacent stator unit and rotor unit. 3A and 3B, the structure of the motor of the present invention having a plurality of stator units and a plurality of rotor units will be described. The motor 4 of Figs. 3A and 3B has three sets of stator units 41 and three sets of rotor units 42, respectively. On the other hand, the stator unit 41 of Figs. 3A and 3B omits the winding core and the first supporting member, and the rotor unit 42 omits the second supporting unit 201203794. When the motor 4 has a plurality of stator units 41, the stator units are stacked and arranged in a dislocation position in the radial direction. In this case, when the two stators 41 are stacked one on another, they are mutually different in electrical-electrical angle. In practice, the inner wall of the wound core of each phase has a groove, and the axial center is provided corresponding to the grooves. The convex groove is disposed, and the convex groove is dislocated. The cooperation of the groove and the convex groove allows the winding core to be fixed to the axis and is misaligned. The purpose of the misalignment setting is to allow the motor 4 to start smoothly without a dead angle. In addition, when the motor 4 has a plurality of rotor units 42, the rotor units c are arranged in a stack, but need not be misaligned. Therefore, the user can assemble and modularize the stator unit 41 and the rotor of the early phase as needed, and then convert the motor into a desired number of phases (for example, a three-phase motor), and improve the product. In addition, the motor 4 can further include A control circuit (not shown) can simultaneously drive two of the coils 412 of the stator unit 41 = the control unit can simultaneously drive the two-phase coil of the motor 4. Of course, the control circuit can also have other driving methods, here. There are no restrictions. 3C and FIG. 3D, FIG. 3C is a front view of FIG. 3B, and a cross-sectional view of the straight line D_D in the 3D. Wherein, the direction of the figure 显示 is shown as the magnetic phase of the stator unit 41 and the rotor unit 42. At the same time point, the control circuit drives the coil 412 of the two subunits simultaneously, so that the two-phase stator unit 41 and the rotary cutter Do not generate 3D magnetic flux. Here, the control circuit simultaneously drives the coil 412 of the stator unit 41 of the lower two phases above the clock 3C of 201203794, but the coil 412 of the stator unit 41 of the intermediate phase is not driven. Therefore, it can be seen that the upper and lower two-phase stator unit 41 and the rotor unit 42 have a three-wire magnetic flux, and the intermediate phase stator unit 41 and the rotor unit 42 do not. Therefore, as described above, the magnetic force of the magnetic element 422 of the intermediate phase rotor unit 42 will be guided by the magnetic conductive element 413 to cause the rotor unit 42 (e.g., the intermediate phase rotor unit 42 of Fig. 3C) not driven by the control unit. The magnetic lines of force of the magnetic element 422 can form a closed magnetic circuit through the guiding of the magnetic conductive element 413, thereby avoiding magnetic leakage of the magnetic element 422 and causing magnetic interference of adjacent phases, thereby improving the output of the motor 4. effectiveness. Further, please refer to Fig. 4, which is a schematic view showing the assembly of the motor 4 of the present invention. The motor 4 further includes a shaft center 43, a housing 44 and two outer covers 45. The second outer cover 45 is provided with the stator unit 41 and the rotor unit 42 , and the shaft 43 is threaded through the setting subunit 41 , the rotor unit 42 and the second outer cover 45 , and is disposed between the shaft center 43 and the outer cover 45 . Bearing. Further, the casing 44 is connected to the rotor unit 42 and the two outer covers 45, respectively. When the control circuit drives the coil 412 of the stator unit 41, the resulting three-dimensional magnetic circuit drives the rotor unit 42 to rotate, and the rotor unit 42 drives the housing 44 and the outer cover 45 coupled thereto to rotate. Further, the shaft center 43 is fixed to the stator unit 41. In addition, please refer to FIG. 5, which is a schematic diagram of an electronic device 5 of the present invention.

Here, the electronic device 5 is exemplified by an electric motor vehicle, but is not limited thereto. In the present embodiment, except for the motor 7, the remaining components can be regarded as the actuating unit 6 of the present invention, including the tire, the bracket and the like. The motor 7 is driven to actuate the unit 6. In other words, when the motor 7 is rotated, the actuating unit 6 can be simultaneously actuated. The motor 7 comprises at least a certain subunit, at least one rotor unit. The stator ϋ ^ unit has two stator cores and a coil, and the coils are disposed between the stator cores. The rotor unit ring is disposed on the stator unit, the rotor unit has at least two rotor cores and at least one magnetic element, and the magnetic element is disposed between the rotor cores and disposed opposite to the coils, and the rotor cores are respectively opposite to the stator cores Settings. The motor 7 can further include a shaft center, a casing and two outer covers 75. The shaft center is connected to a frame 61, and the casing is connected to the rotor unit, the outer cover 75 φ and the tire 62. When the motor 7 is rotated, the tire 62 of the actuating unit 6 can be actuated to move the electronic device 5. Further, the components of the motor 7 have the same technical features as the components of the motor 4, and will not be described again. In summary, since the rotor unit of the motor and the electronic device according to the present invention is disposed in the stator unit, the magnetic conductive elements of the stator unit are disposed on the coil and are respectively disposed between the coil and the rotor unit, and the magnetic component is These magnetically conductive elements are looped. Thereby, the magnetic element can be disturbed by the arrangement of the magnetic conductive element without magnetic leakage, thereby interfering with the magnetic flux of the adjacent stator unit and the rotor unit.
