Description

Technical Field

[0001] The invention relates to the technical field of coreless disc motors, and in particular to a nanocrystalline alloy coreless disc motor. Background Art

[0002] The working principle of the coreless disc motor is similar to that of the traditional motor, but it does not have an iron core. This type of motor usually uses windings directly fixed on the external or internal disc of the motor to generate a rotating magnetic field. Since there is no iron core, this design mainly relies on the current of the winding and the magnetic field of the permanent magnet for movement. The nanocrystalline alloy coreless disc motor is a type of coreless disc motor. It has the characteristics of low loss, higher speed and smaller size.

[0003] Announcement No. CN111224474B discloses a disc motor, which includes a stator, a rotor, a position sensor and a control circuit; the stator includes a winding unit, the winding unit is placed between the stator and the rotor, the winding units are 3N in number, every three adjacent winding units form a three-phase winding, and N is a natural number greater than or equal to 1; the position sensor is opposite to the rotor, and the position sensor is used to detect the rotation speed and suspension height of the rotor; the control circuit is electrically connected to the winding unit and the position sensor, and the control circuit is used to receive the detection result of the position sensor, and thereby control the rotation speed and suspension height of the rotor through the winding unit.

[0004] The disc motor monitors the running state of the rotor in real time through a position sensor so that the control circuit can adjust the running state of the rotor in time, thereby solving the problem of low running stability and accuracy of the existing disc motor. However, in actual use, since the distance between the winding on the stator and the magnetic pole on the rotor is fixed, the stator and the rotor will experience different degrees of wear after long-term use, which will cause the distance between the stator and the rotor to increase, affecting the normal operation efficiency of the motor.

[0005] Therefore, a new type of nanocrystalline alloy ironless disc motor can be used to solve the shortcomings of the prior art. Summary of the invention

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. Before using this nanocrystalline alloy coreless disc motor, the spacing between the lower rotor pole and the stator winding can be adjusted by adjusting the components. The spacing between the lower rotor pole and the stator winding can be adjusted according to the degree of wear, thereby offsetting the unstable operation of the motor caused by wear. At the same time, with the use of the lower magnetic conductive block, the magnetic field generated by the upper and lower rotor poles of the lower rotor disc yoke can be magnetically conductive, and the stability of the magnetic field strength can be ensured after adjustment.

[0023] 2. During operation, the nanocrystalline alloy coreless disc motor isolates the stator winding and the lower rotor pole by setting up insulating plates 1 and 2, which not only does not affect the passage of the magnetic field, but also makes the air flow in the gap between the stator winding and the lower rotor pole smoother. There is no obstruction between the stator winding and the lower rotor pole, which reduces air resistance, thereby reducing the vibration amplitude caused by resistance and effectively improving the operation efficiency of the motor.

[0024] 3. During the operation of the nanocrystalline alloy coreless disc motor, the gear rod is removed from the lower end cover, and the sealing ring is automatically lowered to fit with the limit ring under the action of the elastic telescopic rod, so as to seal the annular through hole on the fixing ring 2. In this way, the air between the yoke of the lower rotor disc and the turntable will not enter the fixing ring 2 through the annular through hole, and the air between the yoke of the lower rotor disc and the turntable will only rotate between the yoke of the lower rotor disc and the turntable, without obstruction, and with smooth flow and small air resistance.

[0025] To summarize, the present invention improves the problem of reduced operating efficiency due to wear of the stator and rotor by adjusting the distance between the stator winding and the lower rotor pole inside the motor, thereby effectively improving the efficiency of the motor. At the same time, during the operation of the motor, the air flow inside the motor can be guided to make the air circulation inside the motor smoother, further improving the operating efficiency of the motor. At the same time, the adjustment of the distance between the stator and the rotor can also effectively improve the starting performance of the motor and ensure the stability of other parameters of the motor, which is suitable for different scenarios.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Example 1: Reference Figure 1 , Figure 4 A nanocrystalline alloy ironless disc motor includes an upper end cover 1 and a lower end cover 2 fixedly connected to the upper end cover 1 by bolts; a driving part is installed between the upper end cover 1 and the lower end cover 2, is located inside the upper end cover 1 and the lower end cover 2, and passes through the upper end cover 1. The driving part includes a driving shaft 4, the driving shaft 4 is rotatably connected to the upper end cover 1 through an upper bearing 3, and the driving shaft 4 is rotatably connected to the lower end cover 2 through a lower bearing 10. The upper bearing 3 and the lower bearing 10 are used to limit the driving shaft 4, reduce the probability of eccentricity of the driving shaft 4, and report the linearity of the driving of the driving shaft 4.

[0052] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 4 , Figure 6-Figure 9 , Fig.12The stator part is composed of two groups of stator assemblies, one of which is installed on the upper end cover 1, and the other is installed on the lower end cover 2. The stator assembly serves as the stator part of the motor and is used to generate an electric field when energized.

[0053] The stator assembly includes a rotating disk 21 fixedly mounted on the drive shaft 4, a stator disk 9 is mounted on the rotating disk 21, a groove 1 is opened on the upper portion of the stator disk 9, and a groove 2 is opened on the lower portion of the stator disk 9, a plurality of stator windings 8 are fixedly mounted in the groove 2, an insulating disk 15 matched with the groove 2 is fixedly mounted on the bottom of the stator disk 9, the stator winding 8 is mounted inside the groove 2 in the stator disk 9, the volume of the stator assembly can be effectively reduced, thereby realizing the miniaturization of the motor, and with the use of the insulating disk 15, the groove 2 can be blocked to prevent the air in the motor from entering the groove 2 to cause air turbulence, effectively reducing the resistance of the air flow, thereby reducing vibration.

[0054] The rotating disk 21 and the stator disk 9 are rotatably connected via a bearing, and a mechanical rotating sealing component is installed between the rotating disk 21 and the stator disk 9. The function of the rotating disk 21 is to limit the stator disk 9. Since the thickness of the stator disk 9 is relatively thin, generally less than one centimeter, when a large amount of heat is generated during high-speed operation, the stator disk 9 will deform to a certain extent under the action of high temperature. At this time, the stator disk 9 is supported by the rotating disk 21 to reduce the probability of deformation of the stator disk 9. The purpose of using a mechanical seal rotating connection between the rotating disk 21 and the drive shaft 4 is to prevent air from penetrating the gap between the rotating disk 21 and the drive shaft 4, so as to avoid air turbulence in the motor. The mechanical rotating sealing component is an existing rotatable connection component with certain sealing performance, which is not elaborated here.

[0055] Embodiment 3: This embodiment is different from the technical solution of Embodiment 2 in that: Figure 1-Figure 8 , Figure 10-Figure 22 The rotor part is fixedly connected to the driving shaft 4. The rotor part includes a movable rotor assembly and a fixed rotor assembly. The rotor part cooperates with the stator part and is divided into two groups, an upper group and a lower group. The distance between the movable rotor assembly and the corresponding stator part is adjusted by the adjusting assembly 14, and the distance between the fixed rotor assembly and the corresponding stator part is fixed.

[0056] The fixed rotor assembly includes an upper rotor disk yoke 5 fixedly mounted on the drive shaft 4, and a plurality of upper rotor poles 17 matching the stator winding 8 are fixedly mounted on the upper rotor disk yoke 5. Each upper rotor pole 17 is located in a groove 1 on the stator disk 9, and an air gap 6 is left between each upper rotor pole 17 and the stator disk 9. The fixed rotor assembly can provide a stable speed for the motor, and the air gap 6 between the groove 1 and the rotor pole 17 can effectively reduce the wear of the upper rotor pole 17 and the stator disk 9, and will not affect the normal operation of the motor.

[0057] The mobile rotor assembly comprises a lower rotor disk yoke 13 fixedly mounted on the driving shaft 4 , and a plurality of lower rotor poles 19 matched with the stator winding 8 are fixedly mounted on the lower rotor disk yoke 13 .

[0058] An upper magnetic conductive block 18 is fixedly installed between two adjacent upper rotor poles 17, and the thickness of the upper magnetic conductive block 18 is the same as that of the upper rotor pole 17. A lower magnetic conductive block 20 is fixedly installed between two adjacent lower rotor poles 19, and the thickness of each lower magnetic conductive block 20 is greater than that of the lower rotor pole 19. An insulating disk 2 16 that matches the insulating disk 1 15 is fixedly installed on the multiple lower magnetic conductive blocks 20.

[0059] The function of the upper magnetic block 18 is to reduce the mutual influence of the magnetic fields on the sides of two adjacent upper rotor poles 17 to ensure the stability and uniformity of the magnetic field. At the same time, multiple upper rotor poles 17 and multiple upper magnetic blocks 18 cooperate to form a ring, which can effectively prevent air turbulence.

[0060] The thickness of each lower magnetic conductive block 20 is greater than the thickness of the lower rotor pole 19, so that the magnetic field generated by the lower rotor pole 19 can be guided, and the magnetic field around the lower rotor pole 19 can also be guided upward to enhance the vertical upward magnetic field strength. The upper magnetic conductive block 18 and the lower magnetic conductive block 20 are collectively referred to as magnetic conductive blocks, which are existing technical features, are made of metal material, and have certain magnetic conductive functions.

[0061] The function of the insulating disk 2 16 is to block the lower magnetic block 20 and seal the gap between the lower magnetic block 20 and the insulating disk 1 15 to prevent the air in the gap between the lower magnetic block 20 and the insulating disk 15 from entering the lower magnetic block 20 and causing air flow obstruction, thereby making the air flow smoother and reducing air resistance, thereby improving the overall performance of the motor.

[0062] The adjustment assembly 14 includes a lifting mechanism and a sealing mechanism. The lifting mechanism is used to adjust the position of the lower rotor disk yoke 13 and change the distance between the lower rotor pole 19 and the corresponding stator winding 8. The sealing mechanism is used to seal the lifting mechanism to reduce air resistance.

[0063] The lifting mechanism includes a turntable 7 fixedly mounted on the driving shaft 4, a fixing ring 26 is fixedly mounted on the turntable 7, the interior of the fixing ring 26 is hollow, a fixing ring 1 23 is fixedly mounted on the fixing ring 26, a connecting ring 22 fixedly connected to the lower rotor disk yoke 13 is slidably mounted on the fixing ring 1 23, a receiving groove matching the connecting ring 22 is provided on the fixing ring 1 23, and an adjustment structure is installed between the fixing ring 26 and the connecting ring 22.

[0064] When adjusting the position of the lower rotor disk yoke 13, the connecting ring 22 will slide in the receiving groove in the fixing ring 26 under the action of the adjusting structure. The fixing ring 1 23, the fixing ring 26 and the connecting ring 22 are all in the shape of circular rings. In this way, when the fixing ring 1 23, the fixing ring 26 and the connecting ring 22 rotate, they will not cause resistance to the air in the motor, thereby ensuring the smoothness of the air flow in the motor.

[0065] The adjustment structure includes an annular through hole provided on the outer side wall of the fixing ring 26, in which a gear ring 28 is rotatably installed, a plurality of rotating blocks 30 are fixedly installed on the inner bottom of the fixing ring 26, a screw rod 29 is rotatably installed on each rotating block 30, each screw rod 29 passes through the bottom of the fixing ring 1 23 and extends into the receiving groove on the fixing ring 1 23, a nut 33 is threadedly rotatably installed on each screw rod 29, a disc 34 is fixedly installed on each nut 33, a plurality of connecting rods 35 are fixedly installed on each disc 34, each connecting rod 35 is fixedly connected to the bottom of the connecting ring 22, a circular hole is provided at the bottom of the fixing ring 1 23 for the disc 34 to pass through, two adjustment sockets 11 are provided on the lower end cover 2, and a gear rod 12 matching the gear ring 28 is inserted into the two adjustment sockets 11.

[0066] First, the gear rod 12 is inserted into one of the adjustment sockets 11 close to the side away from the central axis of the drive shaft 4, and then passed through the other adjustment socket 11, and then the gear rod 12 is moved in the adjustment socket 11 to the side close to the gear ring 28 until the gear ring 28 and the gear rod 12 are meshed, and then the gear rod 12 is locked. There are many existing structures for locking after insertion, which are not specifically described here for the convenience of description, and are not shown in the figure. After the gear rod 12 is locked, the gear rod 12 will only slide back and forth between the two adjustment sockets 11. When adjusting, it is only necessary to pull the gear rod 12. The pulling distance of the gear rod 12 is determined according to the parameters to be adjusted. The gear rod 12 drives the gear ring 28 to rotate, thereby driving the gear 32 to rotate. The rotation of the gear 32 drives the screw rod 29 to rotate, thereby driving the nut 33 and the disc 34 to move on the screw rod 29. The movement of the disc 34 will drive the connecting ring 22 to move through the connecting rod 35, thereby realizing the position adjustment of the connecting ring 22, that is, the position adjustment of the lower rotor disk yoke 13.

[0067] The blocking mechanism includes a telescopic ring 24 fixedly mounted on a second fixing ring 26, a plurality of elastic telescopic rods 31 fixedly mounted inside the telescopic ring 24, a blocking ring 27 matched with the annular through hole fixedly mounted at the bottom of the telescopic ring 24, the bottom of the blocking ring 27 adopts a recessed design matched with the gear rod 12, a limiting ring 25 matched with the gear rod 12 fixedly mounted on the second fixing ring 26, the limiting ring 25 is located below the blocking ring 27 and abuts against the blocking ring 27.

[0068] When the gear rod 12 moves in the adjustment socket 11 toward the side close to the gear ring 28, the gear rod 12 will move along the upper edge of the limit ring 25, and the gear rod 12 will generate a pressing force on the blocking ring 27, and the pressing force will press the lower part of the blocking ring 27. Since the lower part of the blocking ring 27 adopts a concave design, according to the decomposition of the force, the low pressure will produce separation in the vertical direction, and the component force presses the blocking ring 27 to move the blocking ring 27 upward, and the movement of the blocking ring 27 will release the annular through hole. The ring-shaped through hole is sealed and exposed. At this time, the gear rod 12 continues to be moved, and the gear rod 12 will mesh with the gear ring 28 in the ring-shaped through hole. When the adjustment is completed, the gear rod 12 is pulled out, and the sealing ring 27 will automatically move down and fit with the limit ring 25 under the action of the elastic telescopic rod 31 and the telescopic ring 24 to seal the ring-shaped through hole. The purpose of this design is to isolate the inside of the ring-shaped through hole from the outside, avoid turbulence in air flow, make the flow of the time controller smoother, and improve the operating efficiency of the motor.

[0069] The specific operation steps of this device are as follows:

[0070] Position adjustment of the lower rotor disk yoke 13: First, insert the gear rod 12 from one of the adjustment sockets 11 close to the side away from the central axis of the drive shaft 4, and then pass it out from the other adjustment socket 11, and then move the gear rod 12 in the adjustment socket 11 to the side close to the gear ring 28. When the gear rod 12 moves in the adjustment socket 11 to the side close to the gear ring 28, the gear rod 12 will move along the upper edge of the limit ring 25, and the gear rod 12 will produce a pressing force on the blocking ring 27. The pressing force will press the lower part of the blocking ring 27. Since the lower part of the blocking ring 27 adopts a concave design, according to the decomposition of force, the low pressure will produce separation in the vertical direction, and the component force presses the blocking ring 27 to move the blocking ring 27 upward. The movement of the blocking ring 27 will release the blockage of the annular through hole, exposing the annular through hole. At this time, continue to move the gear rod 12, and the gear rod 12 will mesh with the gear ring 28 in the annular through hole.

[0071] When the adjustment is completed, the gear rod 12 is pulled out, and the blocking ring 27 automatically moves down and fits with the limit ring 25 under the action of the elastic telescopic rod 31 and the telescopic ring 24 to block the annular through hole. The purpose of this design is to isolate the inside of the annular through hole from the outside, avoid turbulence in the air flow, make the time controller flow smoother, and improve the operating efficiency of the motor;

[0072] Until the gear ring 28 and the gear rod 12 are meshed, the gear rod 12 is then locked. There are many existing structures that lock after insertion. For the sake of convenience of description, they are not elaborated here and are not shown in the figure. After the gear rod 12 is locked, the gear rod 12 will only slide back and forth between the two adjustment holes 11. When adjusting, you only need to pull the gear rod 12. The pulling distance of the gear rod 12 is determined according to the parameters that need to be adjusted. The gear rod 12 drives the gear ring 28 to rotate, thereby driving the gear 32 to rotate. The rotation of the gear 32 drives the screw rod 29 to rotate, thereby driving the nut 33 and the disk 34 to move on the screw rod 29. The movement of the disk 34 will drive the connecting ring 22 to move through the connecting rod 35, thereby realizing the position adjustment of the connecting ring 22, that is, the position adjustment of the lower rotor disk yoke 13.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
