Description

Technical Field

[0001] The present application relates to the field of motors, and in particular to a high-efficiency amorphous motor. Background Art

[0002] Traditional motors mostly use silicon steel sheets as core materials. Although the cost is low, the overall efficiency is low due to the large loss. With the advancement of technology, amorphous alloys have been introduced into the motor industry as a new material. Amorphous motors have gradually gained favor in the market due to their low loss and high efficiency, becoming one of the key ways to improve motor efficiency.

[0003] In the related art, since the part of the coil that is tangential to the direction of the magnetic field will do work, and the part that is parallel to the direction of the magnetic field will not do work, copper loss will occur, and the stator will heat up, which will lead to lower motor efficiency. Summary of the invention

[0004] In order to reduce copper loss and improve the efficiency of the motor, the present application provides a high-efficiency amorphous motor.

[0005] The present application provides a high-efficiency amorphous motor using the following technical solutions: A high-efficiency amorphous motor, comprising: The motor housing is provided with a containing cavity; A shaft core is rotatably disposed on the motor housing; A wiring board, fixedly connected to the inner wall of the accommodating cavity, wherein the wiring board is perpendicular to the shaft core; A winding frame connected to the axial end surface of the wiring board, the winding frame is in a hollow ring shape, and the winding frame is used for the coil to be spirally wound along its own ring-shaped direction; A stator core is arranged in the inner cavity of the winding frame; The rotor is sleeved on the shaft core.

[0006] By adopting the above technical solution, since the coil is wound in a circular shape of the winding frame and is also spirally wound, the portion of the coil parallel to the direction of the magnetic field will be smaller, so the portion of the coil that does not do work will be smaller, which can reduce copper loss and thus improve the efficiency of the motor.

[0007] Preferably, the circumferential outer wall and the axial side wall of the winding frame are both provided with wire spacers.

[0008] By adopting the above technical solution, the coil can be prevented from deviating during winding, and at the same time, there is no wire separator on the inner wall of the peripheral side, which also facilitates the winding of the coil between different areas of the winding frame.

[0009] Preferably, there are two shaft cores, which are an inner shaft core and an outer shaft core respectively, and a shaft stabilizing plate is arranged between the inner shaft core and the outer shaft core, and the shaft stabilizing plate is connected to the end surface of the winding frame away from the terminal board, and the shaft stabilizing plate is passed through one end of the inner shaft core and the outer shaft core which are close to each other; there are two rotors, which are an inner rotor and an outer rotor respectively, and the inner rotor is located on the inner side of the winding frame, and the inner rotor is connected to the inner shaft core, and the outer rotor is in a cover shape, and the outer rotor covers the winding frame and the shaft stabilizing plate, and the top of the outer rotor is connected to the outer shaft core, and the side of the outer rotor corresponds to the position of the winding frame; the inner rotor and the outer rotor are both connected to a locking assembly.

[0010] By adopting the above technical solution, due to the special winding method of the coil, there are coils on the inside and outside of the stator core, so the rotating magnetic field generated by the stator core and the coil is on the inside and outside of the stator core, so an inner rotor and an outer rotor can be provided, and a locking assembly can be provided at the same time, so that one of the inner rotor or the outer rotor can be rotated, or the inner rotor and the outer rotor can be rotated together, thereby expanding the application range of the motor.

[0011] Preferably, a differential control component is provided between the inner rotor and the outer rotor for changing the speed ratio between the inner rotor and the outer rotor.

[0012] By adopting the above technical solution, due to the setting of the differential control component, when both the inner rotor and the outer rotor can rotate, the speed ratio between the inner rotor and the outer rotor can be changed, thereby further expanding the application range of the motor.

[0013] Preferably, the motor housing is provided with a mounting hole, the center line of which is parallel to the axis of the shaft core; the differential control assembly comprises a connecting column, a shielding ring, an extension spring and a retraction magnet, the connecting column is slidably inserted into the mounting hole, and the sliding direction of the connecting column is parallel to the center line direction of the shaft core; the shielding ring is arranged in the accommodating cavity, the shielding ring is connected to one end of the connecting column close to the accommodating cavity, and the plurality of shielding rings are divided into two groups, one group is located between the winding frame and the inner rotor, and the other group is located between the winding frame and the outer rotor, and the plurality of shielding rings in each group are arranged in a spaced manner; the extension spring is arranged in the mounting hole, the extension spring is connected to the connecting column, and is used to make the shielding ring enter the inner side or the outer side of the circle corresponding to the winding frame; the retraction magnet is connected to the opening of the mounting hole away from the end of the shielding ring, and the retraction magnet is magnetically connected to the connecting column, and is used to make the shielding ring leave the inner side or the outer side of the circle corresponding to the winding frame.

[0014] By adopting the above technical solution, when the retracting magnet is started to absorb the connecting column, the shielding ring will leave the area between the winding frame and the rotor. When the retracting magnet is closed, the shielding ring will enter the area between the winding frame and the rotor under the action of the extending spring. Therefore, the shielding ring can be used to change the magnetic field strength at the position of the rotor, thereby changing the rotational speed of the inner rotor and the outer rotor respectively, and also changing the rotational speed ratio between the inner rotor and the outer rotor.

[0015] Preferably, in each group of the shielding rings, the shielding rings that are closer to the winding frame are thicker.

[0016] By adopting the above technical solution, since the magnetic field strength is higher at the distance from the stator core, the thickness of the shielding ring at different positions is different, so the magnetic field strength at the rotor position can be weakened by an equal amount, thereby more accurately adjusting the rotor speed.

[0017] Preferably, the locking assembly includes a locking static ring, a locking movable ring, a locking magnet and a loose spring, the locking static ring is sleeved on the portion of the inner shaft core or the outer shaft core outside the accommodating cavity, and the locking static ring is made of elastic material; the locking movable ring is slidably sleeved on the portion of the inner shaft core or the outer shaft core outside the accommodating cavity, the locking movable ring and the shaft core are gap-connected, and the locking movable ring and the locking static ring are tightly-fitted; the locking magnet is arranged on the outer wall of the motor housing, and the locking magnet magnetically attracts the locking movable ring to make the locking movable ring sleeved on the locking static ring; one end of the loose spring is connected to the outer wall of the motor housing, and the other end is connected to the locking movable ring to make the locking ring fall off from the locking static ring.

[0018] By adopting the above technical solution, when it is necessary to stop the rotor from rotating, all the shielding rings can be extended to reduce the magnetic field strength of the rotor to the minimum value. At the same time, the locking magnet is started to allow the locking movable ring to be inserted into the locking static ring, so that the purpose of braking the rotor can be achieved with the help of the damping between the locking movable ring and the locking static ring.

[0019] Preferably, an inner and outer matching rod is provided at one end of the outer shaft core close to the inner shaft core, and the inner and outer matching rod passes through the end face of the inner shaft core away from the outer shaft core; a precision matching component is provided between the inner and outer matching rod and the inner shaft core, and the precision matching component is used to fine-tune the speed ratio between the inner shaft core and the outer shaft core.

[0020] By adopting the above technical solution, although the speed ratio between the inner rotor and the outer rotor can be changed by the different numbers of shielding rings between the inner rotor and the stator core, and between the outer rotor and the stator core, the speed ratio between the inner rotor and the outer rotor is still not accurate enough due to the unevenness of the change in the intensity of the rotating magnetic field, so the setting of the precise matching component can further fine-tune the speed ratio between the inner rotor and the outer rotor on this basis, thereby improving the accuracy of the speed ratio between the inner rotor and the outer rotor.

[0021] Preferably, the precision matching assembly includes a driving wheel, a driven wheel, an adjusting main shaft, an adjusting secondary shaft, an adjusting spherical wheel, a swinging gear, a swinging rack, an adjusting spring and an adjusting magnet; the driving wheel is sleeved on the portion of the inner shaft core outside the accommodating cavity; the driven wheel is sleeved on the portion of the inner and outer matching rods outside the accommodating cavity; the adjusting main shaft is rotatably arranged on the outer wall of the motor housing, the adjusting main shaft is parallel to the axis of the inner shaft core, and the adjusting main shaft is parallel to the end faces of the driving wheel and the driven wheel that are close to each other; the adjusting secondary shaft is rotatably connected to the adjusting main shaft, and the adjusting secondary shaft is rotatably connected to the adjusting main shaft The adjusting spherical wheel is hemispherical, the center of the adjusting spherical wheel is connected to the adjusting secondary shaft, and the spherical surface of the adjusting spherical wheel is in rolling contact with the driving wheel and the driven wheel; the swinging gear is sleeved on the adjusting main shaft; the swinging rack is slidably connected to the motor housing, and the swinging rack is meshed with the swinging gear; one end of the adjusting spring is connected to the outer wall of the motor housing, and the other end is connected to the swinging rack; the adjusting magnet is arranged on the outer wall of the motor housing, and the adjusting magnet magnetically attracts the swinging rack, and is used to cooperate with the adjusting spring to change the position of the swinging rack.

[0022] By adopting the above technical solution, the position of the swing rack is changed by cooperating with the adjusting magnet and the adjusting spring, and the direction of the adjusting spherical wheel is changed by cooperating with the swing rack and the swing gear, so that the driving wheel and the driven wheel respectively abut against the circumference of the adjusting spherical wheel with different diameters, so that the transmission ratio between the inner and outer matching rods and the inner shaft core can be changed, so that the speed ratio between the inner rotor and the outer rotor can be precisely adjusted.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: Because the coil is wound in a circular shape on the winding frame and is also wound in a spiral shape, the portion of the coil parallel to the direction of the magnetic field will be smaller, so the portion of the coil that does not do work will be smaller, which can reduce copper loss and thus improve the efficiency of the motor; Due to the special winding method of the coil, there are coils on both the inside and outside of the stator core, so the rotating magnetic field generated by the stator core and the coil is on both the inside and outside of the stator core, so an inner rotor and an outer rotor can be provided, and a locking assembly can be provided at the same time, so that either the inner rotor or the outer rotor can be rotated, or the inner rotor and the outer rotor can be rotated together, thereby expanding the application range of the motor; Due to the setting of the differential control component, when both the inner rotor and the outer rotor can rotate, the speed ratio between the inner rotor and the outer rotor can be changed, thereby further expanding the application range of the motor.

[0029] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0030] The embodiment of the present application discloses a high-efficiency amorphous motor.

[0031] Reference Figure 1 and Figure 2The high-efficiency amorphous motor includes a motor housing 1, an axis core 2, a terminal block 3, a winding frame 4, a stator core 5 and a rotor 6. The motor housing 1 is integrally formed with a receiving cavity 11; the axis core 2 is rotatably penetrated on the motor housing 1; the terminal block 3 is fixedly connected to the inner wall of the receiving cavity 11, and the terminal block 3 allows the axis core 2 to pass through, and the terminal block 3 is perpendicular to the axis core 2; the winding frame 4 is connected to one of the axial end faces of the terminal block 3, and the winding frame 4 is a hollow ring. The winding frame 4 is used for winding the coil, and the winding method is spiral winding, and the winding direction is around the center of the axis core 2; the stator core 5 is fixedly installed in the inner cavity of the winding frame 4; the rotor 6 is sleeved on the axis core 2. In summary, due to the special winding method of the coil, the part of the coil parallel to the magnetic field direction will be less, so the part of the coil that does not do work will be less, which can reduce copper loss, thereby improving the efficiency of the motor.

[0032] Reference Figure 1 and Figure 2 In order to prevent the coil from deviating during the winding process, the circumferential outer wall and the axial side wall of the winding frame 4 are integrally formed with wire spacer blocks 41. Multiple wire spacer blocks 41 are evenly distributed in a circle around the center of the winding frame 4. This can prevent the coil from deviating and allow the coil to be smoothly wound between different areas of the winding frame 4.

[0033] Reference Figure 1 Since there are coils on both the inner and outer sides of the stator core 5, the rotating magnetic field generated by the stator core 5 exists on both the inner and outer sides of the stator core 5. Based on this condition, in order to further expand the application scope of the motor, the following settings are correspondingly provided. First, there are two shaft cores 2, which are an inner shaft core 21 and an outer shaft core 22 respectively. A stabilizing plate 12 is provided between the inner shaft core 21 and the outer shaft core 22. The stabilizing plate 12 is connected to the end face of the winding frame 4 away from the terminal board 3, and the stabilizing plate 12 is provided for passing through the end where the inner shaft core 21 and the outer shaft core 22 are close to each other.

[0034] Reference Figure 1 Secondly, two rotors 6 are provided, and the two rotors 6 are an inner rotor 61 and an outer rotor 62. The inner rotor 61 is located on the inner side of the winding frame 4, and the inner rotor 61 is connected to the inner shaft core 21. The outer rotor 62 is in a cover shape, and the outer rotor 62 covers the winding frame 4 and the shaft stabilizing plate 12. The top of the outer rotor 62 is connected to the outer shaft core 22, and the side of the outer rotor 62 corresponds to the position of the winding frame 4. At the same time, the inner rotor 61 and the outer rotor 62 are both connected with a locking assembly 7, so that either the inner rotor 61 or the outer rotor 62 can be rotated, or the inner rotor 61 and the outer rotor 62 can be rotated together, thereby expanding the application range of the motor.

[0035] Reference Figure 1 and Figure 3In the case where both the inner rotor 61 and the outer rotor 62 can rotate, the speed ratio between the inner rotor 61 and the outer rotor 62 can also be adjusted, and a differential control component 8 is also provided. In order to cooperate with the setting of the differential control component 8, a mounting hole 13 is opened on the motor housing 1, and the center line of the mounting hole 13 is parallel to the axis of the shaft core 2, and a plurality of mounting holes 13 are provided, and the plurality of mounting holes 13 are evenly distributed around the axis of the shaft core 2, so as to provide an installation space for the differential control component 8.

[0036] Reference Figure 1 and Figure 3 Specifically, the differential control assembly 8 includes a connecting column 81, a shielding ring 82, an extending spring 83 and a retracting magnet 84. The connecting column 81 is slidably inserted into the mounting hole 13, and the sliding direction of the connecting column 81 is parallel to the center line direction of the shaft core 2; the shielding ring 82 is arranged in the accommodating cavity 11, and the shielding ring 82 is connected to one end of the connecting column 81 close to the accommodating cavity 11. The multiple shielding rings 82 are divided into two groups, one group is located between the winding frame 4 and the inner rotor 61, and the other group is located between the winding frame 4 and the outer rotor 62. In each group, the multiple shielding rings 82 are arranged in a spaced manner.

[0037] Reference Figure 1 and Figure 3 The extending spring 83 is arranged in the mounting hole 13, and the extending spring 83 is connected to the connecting column 81. In a natural state, the shielding ring 82 will enter the inner side or the outer side of the circle corresponding to the winding frame 4; the retracting magnet 84 is connected to the hole opening of the mounting hole 13 away from the end of the shielding ring 82, and the retracting magnet 84 magnetically attracts the connecting column 81 to make the shielding ring 82 leave the inner side or the outer side of the circle corresponding to the winding frame 4, so the shielding ring 82 can be used to change the magnetic field strength at the position of the rotor 6, so that the rotation speed of the inner rotor 61 and the outer rotor 62 can be changed, and the rotation speed ratio between the inner rotor 61 and the outer rotor 62 can also be changed.

[0038] In addition, in this embodiment, considering that the magnetic field strength is greater at the stator core 5 , the shielding ring 82 closer to the winding frame 4 is thicker.

[0039] Reference Figure 1 and Figure 4 Due to the unevenness of the change in the intensity of the rotating magnetic field, in order to further improve the accuracy of the speed ratio between the inner rotor 61 and the outer rotor 62, the following settings are correspondingly arranged: an inner and outer matching rod 14 is coaxially fixed to one end of the outer shaft core 22 close to the inner shaft core 21, and the inner and outer matching rod 14 passes through the end surface of the inner shaft core 21 away from the outer shaft core 22. At the same time, a precision matching component 9 is arranged between the inner and outer matching rod 14 and the inner shaft core 21 to fine-tune the speed ratio between the inner shaft core 21 and the outer shaft core 22.

[0040] Reference Figure 1 and Figure 4The precision matching assembly 9 includes a driving wheel 91, a driven wheel 92, an adjusting main shaft 93, an adjusting secondary shaft 94, an adjusting spherical wheel 95, a swinging gear 96, a swinging rack 97, an adjusting spring 98 and an adjusting magnet 99. The driving wheel 91 is sleeved on the portion of the inner shaft core 21 outside the accommodating cavity 11, and the driven wheel 92 is sleeved on the portion of the inner and outer matching rods 14 outside the accommodating cavity 11. The wheel diameters of the driving wheel 91 and the driven wheel 92 are the same; the adjusting main shaft 93 is rotatably arranged on the outer wall of the motor housing 1, and the adjusting main shaft 93 is parallel to the inner shaft core 21, the adjusting main shaft 93 is parallel to the end faces of the driving wheel 91 and the driven wheel 92 which are close to each other; the adjusting secondary shaft 94 is rotatably connected to the adjusting main shaft 93, and the adjusting secondary shaft 94 is perpendicular to the adjusting main shaft 93; the adjusting spherical wheel 95 is hemispherical, and the center of the adjusting spherical wheel 95 is connected to the adjusting secondary shaft 94, and the spherical surface of the adjusting spherical wheel 95 is in rolling contact with the driving wheel 91 and the driven wheel 92, so that the driving wheel 91 and the driven wheel 92 can respectively contact the circumference of the adjusting spherical wheel 95 with different diameters, so as to achieve different transmission ratios.

[0041] Reference Figure 1 and Figure 4 , a swing gear 96 is coaxially fixedly sleeved on the adjusting main shaft 93; a swing rack 97 is slidably connected to the motor housing 1, and the sliding direction of the swing rack 97 is parallel to the axial direction of the inner and outer matching rods 14, and the swing rack 97 is meshed with the swing gear 96; one end of the adjustment spring 98 is connected to the outer wall of the motor housing 1, and the other end is connected to the swing rack 97; an adjustment magnet 99 is arranged on the outer wall of the motor housing 1, and the adjustment magnet 99 magnetically attracts the swing rack 97. The adjustment magnet 99 cooperates with the adjustment spring 98 to change the position of the swing rack 97, thereby changing the direction of the adjustment spherical wheel 95, so that the speed ratio between the inner rotor 61 and the outer rotor 62 can be precisely adjusted.

[0042] Reference Figure 1 and Figure 4In order to brake the inner rotor 61 or the outer rotor 62 more simply, the shielding ring 82 can be used to weaken the magnetic field strength of the rotor 6, that is, a little resistance can be applied when the magnetic field strength of the rotor 6 is the smallest to form braking. Specifically, the locking assembly 7 includes a locking static ring 71, a locking dynamic ring 72, a locking magnet 73 and a loose spring 74. The locking static ring 71 is sleeved on the portion of the inner shaft core 21 or the outer shaft core 22 outside the accommodating chamber 11. The locking static ring 71 is made of elastic material; the locking dynamic ring 72 is slidably sleeved on the portion of the inner shaft core 21 or the outer shaft core 22 outside the accommodating chamber 11. The locking ring 72 and the shaft core 2 are connected with each other with a gap, and the locking ring 72 and the locking static ring 71 are connected with each other with a tight fit; the locking magnet 73 is arranged on the outer wall of the motor housing 1, and the locking magnet 73 magnetically attracts the locking ring 72 so that the locking ring 72 is sleeved on the locking static ring 71; one end of the loose spring 74 is connected to the outer wall of the motor housing 1, and the other end is connected to the locking ring 72. In the natural state, the loose spring 74 will allow the locking ring 72 to fall off from the locking static ring 71, so when the magnetic field strength is relatively low, the rotor 6 can be braked with the help of the damping between the locking ring 72 and the locking static ring 71.

[0043] The implementation principle of a high-efficiency amorphous motor in an embodiment of the present application is as follows: since the coil is wound in a circular shape of a winding frame 4 and is also spirally wound, that is, there are coils on both the inner and outer sides of the stator core 5, the portion of the coil that does not do work will be smaller, which can reduce copper loss and thus improve the efficiency of the motor.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
