Description

A disc motor with a shaft channel Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a disc-type motor with a shaft channel. Background Art

[0002] The motor's drive module primarily consists of a stator and a rotor. An alternating current is fed into the stator, generating a corresponding alternating magnetic field through the magnetic effect of the current, thereby driving the rotor, which is primarily composed of permanent magnets, to rotate. As shown in Figure 1, the rotor of an existing motor is typically connected to a rotating shaft that is used to drive the driven device, thereby driving the rotating components of the driven device to rotate and achieve the effect of power output. Specifically, commonly used driven devices include, but are not limited to, speed reducers and water pumps.

[0003] In order to reduce power generation and increase magnetic assist, the industry has conducted years of exploration. For example, the Chinese invention patent with patent number CN201610075290.5 discloses a disc motor. Through structural optimization and improvement, the entire movement process is magnetically assisted, which can effectively reduce input power and enhance output power, thereby enabling the motor to achieve the effect of low energy consumption and high power, thereby greatly increasing its added value and improving its economic benefits.

[0004] However, the current existing technology still has shortcomings: in order to enable power output, the rotating shaft has become a necessary structure, and the connection between the driven device and the rotating shaft is achieved through components such as couplings, resulting in the existing motors still not reaching the optimal space requirements and output efficiency. Summary of the Invention

[0005] In response to the problems of the prior art, the present invention provides a disc motor with a shaft channel. Through structural optimization, the setting of the motor shaft is omitted, so that the installation between the motor and the driven device is more compact and the efficiency of the rotor output is further improved.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The present invention provides a disc motor with an axial channel, comprising a stator module and at least one rotor module. The stator module and the rotor module can rotate relative to each other. The stator module has at least one induction component. The rotor module comprises a connecting portion and two rotors. The two ends of the connecting portion are respectively connected to the two rotors. Each rotor is provided with at least two magnetic components. The induction component is used to receive an alternating current to generate an alternating magnetic field, and the alternating magnetic field acts on the magnetic component to drive the rotor module to rotate. The stator module is located between the two rotors. An axial channel is provided between the rotor module and the stator module. A hollow connecting portion is provided between the two rotors. The connecting portion is located in the axial channel of the stator module. The axial channel is used to install a device driven by the disc motor, and the rotor module drives the rotating component connected to the device.

[0008] Furthermore, there are multiple induction elements, and the multiple induction elements are distributed in the stator module in a circular array with the center / axial channel of the stator module as the center.

[0009] Furthermore, there are multiple magnetic components, which are distributed in the rotor module in a circular array with the center / axial channel of the stator module as the center, and adjacent magnetic components have opposite magnetic properties.

[0010] Furthermore, the shaft channel passes through the stator and the rotor, and the rotor is located outside the rotating part of the device.

[0011] Furthermore, the magnetic poles at both ends of the magnetic member are parallel to the direction of movement, adjacent magnetic members are opposed to each other with the same poles, the magnetic members of the two rotors are arranged in a one-to-one correspondence, and the corresponding magnetic members are opposed to each other with opposite poles.

[0012] Beneficial effects of the present invention: The present invention saves space by adjusting the positional relationship between the rotor and the stator to be stacked, and providing an axial channel between the rotor and the stator to accommodate the driven device; in addition, the present invention surrounds the rotating shaft of the driven device and drives it, so that the torque is improved, that is, the output efficiency of the rotor is improved.

[0020] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the embodiments and the accompanying drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0021] As shown in Figures 2 to 4, the present invention provides a disc motor with an axial channel, comprising a stator module 1 and at least one rotor module 2. The stator module 1 and the rotor module 2 are rotatable relative to each other. The stator module 1 has at least one induction member 3. The rotor module 2 includes a connecting portion 22 and two rotors 21. The two ends of the connecting portion 22 are respectively connected to the two rotors 21. Each rotor 21 is provided with at least two magnetic members 4. The induction member 3 is used to receive an alternating current to generate an alternating magnetic field. The alternating magnetic field acts on the magnetic members 4 to drive the rotor module 2 to rotate. The stator module 1 is located between the two rotors 21. An axial channel 5 is provided between the rotor module 2 and the stator module 1. The axial channel 5 is used to install a device 6 driven by the disc motor, and the rotor module 2 drives a rotating component 7 connected to the device 6. Specifically, the connection method between the rotor 21 and the rotating component 7 is a conventional structure and will not be repeated here.

[0022] Specifically, the induction component 3 described in this embodiment preferably includes an iron core 31 and a coil 32 wound around the iron core 31, that is, the coil 32 receives an external alternating current to generate an alternating magnetic field to magnetize the iron core 31. Therefore, the distribution of magnetic field lines on the iron core 31 will also change continuously, thereby generating an alternating force on the magnetic component 4; and the magnetic component 4 moves under the drive of the magnetized iron core 31, thereby driving the entire rotor module 2 to rotate relative to the stator module 1, thereby realizing the generation of power.

[0023] Compared with the prior art, the advantage of the present invention is that an axial channel 5 is provided, which passes through the stator and the rotor 21, so that the driven device 6, such as a reducer, a water pump, etc., can be directly installed in the axial channel 5, and the rotating component 7 of the driven device 6 protrudes to the outside through the axial channel 5 of the rotor module 2, and the rotor module 2 can be connected to the rotating component 7 of the driven device 6 through common hardware parts, so that when the rotor module 2 rotates, the rotating component 7 is directly driven to rotate, thereby achieving the effect of omitting the motor's rotating shaft 8 and still being able to output power stably.

[0024] Compared with the traditional motor in which the rotor 21 is located inside the stator or the stator is located inside the rotor 21, the present invention arranges the rotor 21 on one side of the stator. Its driving principle can refer to the scheme disclosed in CN201610075290.5, and the middle part of the rotor 21 and the stator is hollowed out to form an axial channel 5, so that the traditional installation method of arranging the driven device 6 on one side of the motor is changed to arranging the driven device 6 inside the motor, thereby saving space; in addition, unlike the traditional rotor 21 driving the device 6 through the rotating shaft 8, the present invention omits the setting of the rotating shaft 8 and directly connects the rotating part 7 of the driven device 6 to the rotor 21, so that the power of the rotor 21 directly acts on the rotating part 7, which not only improves the output efficiency, but also changes the torque from inside to outside, so that the torque is doubled.

[0025] Specifically, the torque described in this embodiment is internal, which means that the traditional motor is output through the rotating shaft 8, and the rotating shaft 8 needs to be connected to the rotating part 7 through the coupling 9, or the rotating part 7 is sleeved outside the rotating shaft 8 to achieve a drive connection. Therefore, the torque is in the rotating shaft 8 and output from the inside; the present invention is because the rotor 21 is surrounded by the outer periphery of the rotating part 7, so the rotor 21 directly outputs the torque, and the torque has the effect of being outside.

[0026] In this embodiment, there are multiple induction elements 3 , and the multiple induction elements 3 are distributed in the stator module 1 in a circular array with the center / axial channel 5 of the stator module 1 as the center.

[0027] At the same time, there are multiple magnetic members 4, which are distributed in the rotor module 2 in a circular array with the center / axial channel 5 of the stator module 1 as the center, and adjacent magnetic members 4 have opposite magnetic properties.

[0028] That is, the shaft channel 5 is preferably set at the center of the stator and rotor 21, so that the rotor 21 rotates with the shaft channel 5 as the center, thereby driving the rotating component 7 to rotate stably and preventing the rotating component 7 from swinging during rotation and affecting the output effect.

[0029] In this embodiment, the magnetic poles at both ends of the magnetic member 4 are parallel to the direction of movement, adjacent magnetic members 4 have the same poles facing each other, and the magnetic members 4 of the two rotors 21 are arranged in a one-to-one correspondence, with the corresponding magnetic members 4 having opposite poles facing each other.

[0030] Specifically, the distribution of the magnetic members 4 of the two rotors 21 is exactly opposite to each other, so as to ensure that when the induction member 3 generates an alternating magnetic field, the directions of the magnetic field forces acting on the two rotors 21 are consistent, so as to ensure smooth rotation.

[0031] Specifically, the connecting portion 22 is a hollow structure, and the positions of the connecting portion 22 and the stator module 1 are preferably: 1. As shown in Figure 3, the outer diameter of the connecting portion 22 is smaller than the outer diameter of the axial channel 5 of the stator module 1, and the connecting portion 22 is located outside the axial channel 5 of the stator module 1.

[0032] 2. As shown in FIG. 5 , the inner diameter of the connecting portion 22 is larger than the outer diameter of the stator module 1 , and the stator module 1 is located inside the connecting portion 22 .

[0033] 3. As shown in FIG6 , the connecting portion 22 has an outer through hole and an inner through hole, wherein the stator module 1 is located in the outer through hole, and the inner through hole is connected to the axial channel 5 of the stator module 1 and the axial channel 5 of the rotor 21 .

[0034] The above three structures can all be applied to the present invention, thereby ensuring that the connecting portion 22 and the stator module 1 do not interfere with each other, and also ensuring that the driven device 6 can be smoothly installed in the present invention.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention is disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technology of the present invention are all within the scope of the technical solution of the present invention without departing from the content of the technical solution of the present invention.
