Description

A high-efficiency amorphous motor Technical Field

[0001] This application relates to the field of electric motors, and in particular to a high-efficiency amorphous electric motor. Background Technology

[0002] Traditional electric motors mostly use silicon steel sheets as the core material. Although this is inexpensive, it results in low overall efficiency due to significant losses. With technological advancements, amorphous alloys have been introduced into the motor industry as a new material. Amorphous motors, due to their low losses and high efficiency, are gradually gaining market favor and have become one of the key ways to improve motor performance.

[0003] In related technologies, the part of the coil that is tangent to the direction of the magnetic field does work, while the part that is parallel to the direction of the magnetic field does not, resulting in copper loss. This causes the stator to heat up, which leads to low motor efficiency. Invention Overview

[0004] In order to reduce copper losses and improve motor efficiency, this application provides a high-efficiency amorphous motor.

[0005] The high-efficiency amorphous motor provided in this application adopts the following technical solution:

[0006] A high-efficiency amorphous motor, comprising:

[0007] The motor housing has a receiving cavity;

[0008] The shaft is rotatably mounted on the motor housing;

[0009] A terminal block is fixedly connected to the inner wall of the accommodating cavity, and the terminal block is perpendicular to the shaft core;

[0010] A winding frame is connected to the axial end face of the terminal block. The winding frame is in the shape of a hollow ring, and the winding frame allows the coil to be spirally wound along its own annular winding direction.

[0011] The stator core is disposed in the inner cavity of the winding frame;

[0012] The rotor is fitted onto the shaft core.

[0013] By adopting the above technical solution, since the coil is wound in a ring shape on the winding frame and is also wound in a spiral, the portion of the coil parallel to the direction of the magnetic field will be less, so the portion of the coil that does no work will be less, which will reduce copper loss and thus improve the efficiency of the motor.

[0014] Preferably, the outer peripheral wall and the axial side wall of the winding frame are provided with wire dividers.

[0015] By adopting the above technical solution, the coil can be prevented from deviating during winding. At the same time, the absence of wire dividers on the inner wall of the perimeter facilitates the winding of the coil between different areas of the winding frame.

[0016] Preferably, there are two shafts, an inner shaft and an outer shaft, with a stabilizing plate between the inner and outer shafts. The stabilizing plate is connected to the end face of the winding frame away from the terminal block, and the stabilizing plate allows the ends of the inner and outer shafts to pass through. There are two rotors, an inner rotor and an outer rotor. The inner rotor is located inside the winding frame and is connected to the inner shaft. The outer rotor is cap-shaped, covering the winding frame and the stabilizing plate. The top of the outer rotor is connected to the outer shaft, and the side of the outer rotor corresponds to the position of the winding frame. Both the inner and outer rotors are connected to locking components.

[0017] By adopting the above technical solution, due to the special winding method of the coil, there are coils on both the inner and outer sides of the stator core. Therefore, the rotating magnetic field generated by the stator core and the coil will exist on both the inner and outer sides of the stator core. Thus, an inner rotor and an outer rotor can be set. With the addition of a locking component, 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.

[0018] Preferably, a differential speed control component is provided between the inner rotor and the outer rotor to change the speed ratio between the inner rotor and the outer rotor.

[0019] By adopting the above technical solution, due to the setting of the differential control component, the speed ratio between the inner rotor and the outer rotor can be changed when both the inner rotor and the outer rotor can rotate, thereby further expanding the application range of the motor.

[0020] Preferably, the motor housing is provided with a mounting hole, the centerline of which is parallel to the axis of the shaft core; the differential control assembly includes a connecting post, a shielding ring, an extension spring, and a retractable magnet; the connecting post is slidably inserted into the mounting hole, and the sliding direction of the connecting post is parallel to the centerline of the shaft core; the shielding ring is disposed in the receiving cavity, and the shielding ring is connected to the end of the connecting post near the receiving cavity; 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; the plurality of shielding rings in each group are spaced apart; the extension spring is disposed in the mounting hole, and the extension spring is connected to the connecting post, for causing the shielding ring to enter the inner or outer circumference of the winding frame; the retractable magnet is connected to the opening of the mounting hole at the end away from the shielding ring, and the retractable magnet is magnetically connected to the connecting post, for causing the shielding ring to leave the inner or outer circumference of the winding frame.

[0021] By adopting the above technical solution, the retractable magnet is activated to attract the connecting column, and the shielding ring will leave the area between the winding frame and the rotor. When the retractable magnet is closed, the shielding ring will enter the area between the winding frame and the rotor under the action of the extension spring. Therefore, the magnetic field strength at the location of the rotor can be changed by means of the shielding ring, thereby changing both the speed of the inner and outer rotors and the speed ratio between the inner and outer rotors.

[0022] Preferably, the shielding ring closer to the winding frame in each group of shielding rings is thicker.

[0023] By adopting the above technical solution, since the magnetic field strength is higher at a distance from the stator core, the thickness of the shielding ring at different locations is different, which can reduce the magnetic field strength at the rotor location by an equal amount, thereby enabling more accurate adjustment of the rotor speed.

[0024] Preferably, the locking assembly includes a locking stationary ring, a locking moving ring, a locking magnet, and a release spring. The locking stationary ring is sleeved on the portion of the inner shaft or the outer shaft outside the receiving cavity, and the locking stationary ring is made of an elastic material. The locking moving ring is slidably sleeved on the portion of the inner shaft or the outer shaft outside the receiving cavity. The locking moving ring and the shaft are connected with a gap, and the locking moving ring and the locking stationary ring are tightly fitted together. The locking magnet is disposed on the outer wall of the motor housing and magnetically attracts the locking moving ring, thereby causing the locking moving ring to be sleeved on the locking stationary ring. One end of the release spring is connected to the outer wall of the motor housing, and the other end is connected to the locking moving ring, thereby causing the locking moving ring to disengage from the locking stationary ring.

[0025] 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 a minimum. At the same time, the locking magnet is activated to allow the locking stop ring to be fitted onto the locking stationary ring. With the help of the damping between the locking stop ring and the locking stationary ring, the rotor can be braked.

[0026] Preferably, an inner and outer mating rod is provided at one end of the outer shaft core near the inner shaft core, and the inner and outer mating rods extend out of the end face of the inner shaft core away from the outer shaft core; a fine matching component is provided between the inner and outer mating rods and the inner shaft core, and the fine matching component is used to finely adjust the speed ratio between the inner shaft core and the outer shaft core.

[0027] By adopting the above technical solution, although the speed ratio between the inner rotor and the outer rotor can be changed by varying the number 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 will still be inaccurate due to the non-uniformity of the rotating magnetic field intensity. Therefore, the setting of the fine-matching component can further fine-tune the speed ratio between the inner rotor and the outer rotor, thereby improving the accuracy of the speed ratio between the inner rotor and the outer rotor.

[0028] 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 oscillating gear, an oscillating 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, and the driven wheel is sleeved on the portion of the inner and outer mating rods outside the accommodating cavity. The adjusting main shaft is rotatably mounted on the outer wall of the motor housing, parallel to the axis of the inner shaft core, and 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. The adjustment spherical wheel is perpendicular to the motor housing; the center of the adjustment spherical wheel is connected to the adjustment sub-shaft, and the spherical surface of the adjustment spherical wheel rolls against the driving wheel and the driven wheel; the oscillating gear is sleeved on the adjustment main shaft; the oscillating rack is slidably connected to the motor housing, and the oscillating rack meshes with the oscillating 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 oscillating rack; the adjusting magnet is disposed on the outer wall of the motor housing, and the adjusting magnet magnetically attracts the oscillating rack, which is used to cooperate with the adjusting spring to change the position of the oscillating rack.

[0029] By adopting the above technical solution, the position of the oscillating rack is changed by the cooperation of the adjusting magnet and the adjusting spring. Furthermore, the orientation of the adjusting spherical wheel is changed by the cooperation of the oscillating rack and the oscillating gear, so that the driving wheel and the driven wheel abut against the circumference of the adjusting spherical wheel of different diameters respectively. Therefore, the transmission ratio between the inner and outer mating rods and the inner shaft core can be changed, thereby allowing for precise adjustment of the speed ratio between the inner rotor and the outer rotor. Beneficial effects

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] Because the coil is wound in a ring around the winding frame, and also in a spiral shape, the portion of the coil parallel to the direction of the magnetic field will be less, so the portion of the coil that does no work will be less, which will reduce copper losses and thus improve the efficiency of the motor.

[0032] Due to the special winding method of the coil, there are coils on both the inner and outer sides of the stator core. Therefore, the rotating magnetic field generated by the stator core and the coil will exist on both the inner and outer sides of the stator core. Thus, an inner rotor and an outer rotor can be set. With the addition of a locking component, 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.

[0033] Due to the differential control component, the speed ratio between the inner and outer rotors can be changed when both the inner and outer rotors can rotate, thereby further expanding the application range of the motor. Attached Figure Description

[0039] The present application will be further described in detail below with reference to Figures 1-4.

[0040] This application discloses a high-efficiency amorphous motor.

[0041] Referring to Figures 1 and 2, the high-efficiency amorphous motor includes a motor housing 1, a shaft 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 shaft core 2 is rotatably mounted on the motor housing 1. The terminal block 3 is fixedly connected to the inner wall of the receiving cavity 11, allowing the shaft core 2 to pass through. The terminal block 3 is perpendicular to the shaft core 2. The winding frame 4 is connected to one of the axial end faces of the terminal block 3. The winding frame 4 is a hollow ring shape, used for winding the coil. The winding method is helical winding, and the winding direction is around the center of the shaft 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 shaft core 2. In summary, due to the special winding method of the coil, the portion of the coil parallel to the magnetic field direction is less, so the portion of the coil that does no work is less, which reduces copper loss and thus improves the efficiency of the motor.

[0042] Referring to Figures 1 and 2, to prevent the coil from deviating during the winding process, the outer periphery and axial sidewalls of the winding frame 4 are integrally formed with partition blocks 41. Multiple partition blocks 41 are evenly distributed in a circle around the center of the winding frame 4. This can prevent the coil from deviating and also allow the coil to be wound smoothly between different areas of the winding frame 4.

[0043] Referring to Figure 1, since there are coils on both the inner and outer circumferences of the stator core 5, the rotating magnetic field generated by the stator core 5 will exist on both the inner and outer sides of the stator core 5. Based on this condition, in order to further expand the application range of the motor, the following settings are made: First, there are two shaft cores 2, namely an inner shaft core 21 and an outer shaft core 22. 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 plate 3. The stabilizing plate 12 allows the inner shaft core 21 and the outer shaft core 22 to pass through each other.

[0044] Referring to Figure 1, secondly, there are two rotors 6: an inner rotor 61 and an outer rotor 62. The inner rotor 61 is located inside the winding frame 4 and is connected to the inner shaft core 21. The outer rotor 62 is cover-shaped and covers the winding frame 4 and the 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, both the inner rotor 61 and the outer rotor 62 are connected to locking components 7, so that either the inner rotor 61 or the outer rotor 62 can rotate, or the inner rotor 61 and the outer rotor 62 can rotate together, thereby expanding the application range of the motor.

[0045] Referring to Figures 1 and 3, if both the inner rotor 61 and the outer rotor 62 can rotate, and the speed ratio between the inner rotor 61 and the outer rotor 62 can be adjusted, then a differential control component 8 is also provided. In order to accommodate the differential control component 8, a mounting hole 13 is provided on the motor housing 1. The center line of the mounting hole 13 is parallel to the axis of the shaft core 2, and multiple mounting holes 13 are provided. The multiple mounting holes 13 are evenly distributed around the axis of the shaft core 2, thus providing installation space for the differential control component 8.

[0046] Referring to Figures 1 and 3, specifically, the differential control assembly 8 includes a connecting post 81, a shielding ring 82, an extension spring 83, and a retracting magnet 84. The connecting post 81 is slidably inserted into the mounting hole 13, and the sliding direction of the connecting post 81 is parallel to the center line direction of the shaft core 2. The shielding ring 82 is disposed in the receiving cavity 11, and the shielding ring 82 is connected to the end of the connecting post 81 near the receiving 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 spaced apart.

[0047] Referring to Figures 1 and 3, the extending spring 83 is disposed in the mounting hole 13 and connected to the connecting post 81. Under normal conditions, the extending spring 83 allows the shielding ring 82 to enter the inner or outer side of the winding frame 4. The retracting magnet 84 is connected to the opening at the end of the mounting hole 13 away from the shielding ring 82. The retracting magnet 84 magnetically attracts the connecting post 81, causing the shielding ring 82 to leave the inner or outer side of the winding frame 4. Therefore, the magnetic field strength at the location of the rotor 6 can be changed by means of the shielding ring 82, thereby changing both the rotational speed of the inner rotor 61 and the outer rotor 62, as well as the rotational speed ratio between the inner rotor 61 and the outer rotor 62.

[0048] In addition, in this embodiment, considering that the magnetic field strength is greater at a distance from the stator core 5, the shielding ring 82, which is closer to the winding frame 4, will be thicker.

[0049] Referring to Figures 1 and 4, due to the non-uniformity of the rotating magnetic field intensity, in order to further improve the accuracy of the speed ratio between the inner rotor 61 and the outer rotor 62, the following configuration is provided: an inner and outer mating rod 14 is coaxially fixed at one end of the outer shaft core 22 near the inner shaft core 21. The inner and outer mating rod 14 extends out of the end face of the inner shaft core 21 away from the outer shaft core 22. At the same time, a fine matching component 9 is provided between the inner and outer mating rod 14 and the inner shaft core 21 to finely adjust the speed ratio between the inner shaft core 21 and the outer shaft core 22.

[0050] Referring to Figures 1 and 4, the precision matching assembly 9 includes a drive wheel 91, a driven wheel 92, an adjusting main shaft 93, an adjusting secondary shaft 94, an adjusting spherical wheel 95, a oscillating gear 96, an oscillating rack 97, an adjusting spring 98, and an adjusting magnet 99. The drive wheel 91 is sleeved on the portion of the inner shaft core 21 outside the receiving cavity 11, and the driven wheel 92 is sleeved on the portion of the inner and outer mating rods 14 outside the receiving cavity 11. The drive wheel 91 and the driven wheel 92 have the same wheel diameter. The adjusting main shaft 93 is rotatably mounted on the outer wall of the motor housing 1, and the adjusting main shaft 93 is parallel to... On the axis of 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 that are close to each other; the adjusting secondary shaft 94 is rotatably connected to the adjusting main shaft 93 and 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. The spherical surface of the adjusting spherical wheel 95 rolls and abuts against the driving wheel 91 and the driven wheel 92, so that the driving wheel 91 and the driven wheel 92 abut against the circumferences of the adjusting spherical wheel 95 with different diameters, thereby achieving different transmission ratios.

[0051] Referring to Figures 1 and 4, the oscillating gear 96 is coaxially fixedly sleeved on the adjusting main shaft 93; the oscillating rack 97 is slidably connected to the motor housing 1, and the sliding direction of the oscillating rack 97 is parallel to the axial direction of the inner and outer mating rods 14. The oscillating rack 97 meshes with the oscillating gear 96; one end of the adjusting spring 98 is connected to the outer wall of the motor housing 1, and the other end is connected to the oscillating rack 97; the adjusting magnet 99 is set on the outer wall of the motor housing 1, and the adjusting magnet 99 magnetically attracts the oscillating rack 97. The adjusting magnet 99 cooperates with the adjusting spring 98 to change the position of the oscillating rack 97, thereby changing the orientation of the adjusting spherical wheel 95, so as to finely adjust the speed ratio between the inner rotor 61 and the outer rotor 62.

[0052] Referring to Figures 1 and 4, to more easily brake the inner rotor 61 or the outer rotor 62, braking can be achieved by weakening the magnetic field strength of the rotor 6 using the shielding ring 82. Specifically, braking can be achieved by applying a small amount of resistance when the magnetic field strength of the rotor 6 is at its minimum. The locking assembly 7 includes a locking stationary ring 71, a locking moving ring 72, a locking magnet 73, and a release spring 74. The locking stationary ring 71 is sleeved on the portion of the inner shaft core 21 or the outer shaft core 22 outside the receiving cavity 11, and is made of an elastic material. The locking moving ring 72 is slidably sleeved on the portion of the inner shaft core 21 or the outer shaft core 22 outside the receiving cavity 11. In some parts, the locking stop ring 72 and the shaft core 2 are connected by a gap, while the locking stop ring 72 and the locking stationary ring 71 are connected by a tight fit. The locking magnet 73 is set on the outer wall of the motor housing 1, and the locking magnet 73 magnetically attracts the locking stop ring 72 so that the locking stop ring 72 is fitted onto the locking stationary ring 71. One end of the release spring 74 is connected to the outer wall of the motor housing 1, and the other end is connected to the locking stop ring 72. Under natural conditions, the release spring 74 will cause the locking stop ring 72 to disengage from the locking stationary ring 71. Therefore, when the magnetic field strength is relatively low, the rotor 6 can be braked by means of the damping between the locking stop ring 72 and the locking stationary ring 71.

[0053] The implementation principle of a high-efficiency amorphous motor in this application embodiment is as follows: because the coil is wound in a ring shape on the winding frame 4, and is also wound in a spiral shape, that is, there are coils on both the inner and outer circumferences of the stator core 5, the part of the coil that does no work will be less, which can reduce copper loss and thus improve the efficiency of the motor.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
