TECHNICAL FIELD

[0001] The present application relates to the field of electric machines, in particular to a high-efficiency amorphous electric machine. BACKGROUND

[0002] Traditional electric machines mostly use silicon steel sheets as core materials, which are low in cost but have high loss, resulting in low overall efficiency. With the progress of science and technology, amorphous alloys as a new material have been introduced into the electric machine industry. Amorphous electric machines have gradually gained market favor due to their low loss and high efficiency, and have become one of the key ways to improve the efficiency of electric machines.

[0012] A rotor is sleeved on the shaft core.

[0013] By adopting the above technical solution, since the coil is circumferentially wound around the bobbin in a spiral manner, the part of the coil parallel to the magnetic field direction is less, so the part of the coil not doing work is less, which can reduce copper loss and improve the efficiency of the electric machine.

[0014] Preferably, the circumferential side wall and the axial side wall of the bobbin are provided with a wire separation block.

[0015] By adopting the above technical scheme, the coil can be prevented from deviating while being wound, and the coil can be conveniently wound between different regions of the winding frame without the wire separating block on the inner wall of the periphery.

[0016] Preferably, the shaft core is provided with two, the two shaft cores are an inner shaft core and an outer shaft core respectively, a shaft stabilizing plate is arranged between the inner shaft core and the outer shaft core, the shaft stabilizing plate is connected to an end face of the winding frame away from the terminal plate, and the shaft stabilizing plate is provided for the end of the inner shaft core and the outer shaft core that are close to each other; the rotor is provided with two, the two rotors are an inner rotor and an outer rotor respectively, the inner rotor is located on the inner side of the winding frame, the inner rotor is connected to the inner shaft core, the outer rotor is in the form of a cover, the outer rotor covers the winding frame and the shaft stabilizing plate, 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.

[0026] Preferably, the outer shaft core is provided with an inner-outer matching rod near one end of the inner shaft core, the inner-outer matching rod penetrates through the end face of the inner shaft core away from the outer shaft core; the inner-outer matching rod and the inner shaft core are provided with a fine matching assembly therebetween, the fine matching assembly is used for fine tuning the speed ratio between the inner shaft core and the outer shaft core.

[0027] By adopting the technical scheme, although the number of shielding rings between the inner rotor and the stator core and the outer rotor and the stator core can be used to change the speed ratio between the inner rotor and the outer rotor, the speed ratio between the inner rotor and the outer rotor is not accurate due to the non-uniformity of the rotating magnetic field strength. The fine matching assembly 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.

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

[0031] Because the coil is circumferentially wound in the annular shape of the bobbin and is also spirally wound, the portion of the coil parallel to the magnetic field direction is less, so the portion of the coil that does not do work is less, and thus the copper loss can be reduced, thereby improving the efficiency of the motor.

[0044] Referring to Figure 1 The second is that the rotor 6 is provided with two, the two rotors 6 are respectively an inner rotor 61 and an outer rotor 62, the inner rotor 61 is located on the inner side of the bobbin 4, the inner rotor 61 is connected with the inner shaft core 21, the outer rotor 62 is in the form of a cover, the outer rotor 62 covers the bobbin 4 and the shaft stabilizing plate 12, the top of the outer rotor 62 is connected with the outer shaft core 22, and the side of the outer rotor 62 corresponds to the position of the bobbin 4, and the inner rotor 61 and the outer rotor 62 are both connected with the locking assembly 7, so that one of 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 Figure 1 And Figure 3 In the case that 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, so the differential control assembly 8 is also provided, and in order to cooperate with the setting of the differential control assembly 8, the mounting hole 13 is formed on the motor shell 1, 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, the plurality of mounting holes 13 are uniformly distributed around the axis of the shaft core 2, so as to provide the mounting space of the differential control assembly 8.

[0047] Referring to Figure 1 And Figure 3The extension spring 83 is arranged in the mounting hole 13 and connected with the connecting column 81, and in the natural state, the shielding ring 82 enters the corresponding inner or outer side of the bobbin 4; the retracting magnet 84 is connected to the opening of the mounting hole 13 away from the shielding ring 82, and the retracting magnet 84 magnetically attracts the connecting column 81, so that the shielding ring 82 leaves the corresponding inner or outer side of the bobbin 4, so that the magnetic field strength of the position of the rotor 6 can be changed by the shielding ring 82, 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 be changed.

[0048] In addition, in the present embodiment, considering that the magnetic field strength is greater away from the stator core 5, the shielding ring 82 closer to the bobbin 4 is thicker.

[0049] Referring to Figure 1 and Figure 4 , due to the non-uniformity of the change of the rotating magnetic field strength, in order to further improve the accuracy of the rotation speed ratio between the inner rotor 61 and the outer rotor 62, the following arrangement is provided, the inner outer matching rod 14 is coaxially fixed to the end of the outer shaft core 22 close to the inner shaft core 21, the inner outer matching rod 14 penetrates the end surface of the inner shaft core 21 away from the outer shaft core 22, and the inner outer matching rod 14 and the inner shaft core 21 are provided with a precision matching assembly 9 for fine adjustment of the rotation speed ratio between the inner shaft core 21 and the outer shaft core 22.

[0050] Referring to Figure 1 and Figure 4 , the precision matching assembly 9 includes a driving wheel 91, a driven wheel 92, an adjusting main shaft 93, an adjusting auxiliary shaft 94, an adjusting spherical wheel 95, a swing gear 96, a swing rack 97, a position adjusting spring 98 and a position adjusting magnet 99, the driving wheel 91 is sleeved on the part of the inner shaft core 21 outside the accommodating cavity 11, the driven wheel 92 is sleeved on the part of the inner outer matching rod 14 outside the accommodating cavity 11, and the wheel diameters of the driving wheel 91 and the driven wheel 92 are the same; the adjusting main shaft 93 is rotationally arranged on the outer wall of the motor shell 1, the adjusting main shaft 93 is parallel to the axis of the inner shaft core 21, and the adjusting main shaft 93 is parallel to the end faces of the driving wheel 91 and the driven wheel 92 close to each other; the adjusting auxiliary shaft 94 is rotationally connected with the adjusting main shaft 93, and the adjusting auxiliary shaft 94 is perpendicular to the adjusting main shaft 93; the adjusting spherical wheel 95 is semispherical, the spherical center of the adjusting spherical wheel 95 is connected with the adjusting auxiliary shaft 94, and the spherical surface of the adjusting spherical wheel 95 is in rolling abutment with the driving wheel 91 and the driven wheel 92, so that the driving wheel 91 and the driven wheel 92 abut the circumferences with different diameters of the adjusting spherical wheel 95 respectively, so as to realize different transmission ratios.

[0051] Referring to Figure 1 and Figure 4The swing gear 96 is coaxially fixed on the adjusting spindle 93. The swing rack 97 is slidably connected to the motor shell 1, and the sliding direction of the swing rack 97 is parallel to the axial direction of the inner-outer cooperation rod 14. The swing rack 97 is engaged with the swing gear 96. The adjusting spring 98 is connected to the outer wall of the motor shell 1 at one end and connected to the swing rack 97 at the other end. The adjusting magnet 99 is arranged on the outer wall of the motor shell 1. The adjusting magnet 99 magnetically attracts the swing rack 97. The adjusting magnet 99 cooperates with the adjusting spring 98 to change the position of the swing rack 97, so as to change the orientation of the adjusting spherical gear 95, thereby finely adjusting the speed ratio between the inner rotor 61 and the outer rotor 62.

[0052] With reference to Figure 1 and Figure 4 In order to more simply brake the inner rotor 61 or the outer rotor 62, the magnetic field strength at which the rotor 6 is located can be weakened, that is, a little resistance is applied when the magnetic field strength at which the rotor 6 is located is the smallest to form the brake. 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 part of the inner shaft core 21 or the outer shaft core 22 outside the accommodating cavity 11 and is made of an elastic material. The locking dynamic ring 72 is slidably sleeved on the part of the inner shaft core 21 or the outer shaft core 22 outside the accommodating cavity 11. The locking dynamic ring 72 is connected to the shaft core 2 in a gap connection, and the locking dynamic ring 72 is connected to the locking static ring 71 in a tight fit connection. The locking magnet 73 is arranged on the outer wall of the motor shell 1. The locking magnet 73 magnetically attracts the locking dynamic ring 72 to make the locking dynamic ring 72 be sleeved on the locking static ring 71. One end of the loose spring 74 is connected to the outer wall of the motor shell 1, and the other end is connected to the locking dynamic ring 72. In a natural state, the loose spring 74 makes the locking dynamic ring 72 be separated from the locking static ring 71. Therefore, in the case that the magnetic field strength is relatively low, the damping between the locking dynamic ring 72 and the locking static ring 71 can be used to brake the rotor 6.

[0053] The implementation principle of the high-efficiency amorphous motor of the embodiment of the application is that the coil is circumferentially wound around the ring-shaped bobbin 4 and is also spirally wound, that is, the inner circumferential side and the outer circumferential side of the stator core 5 both have coils. Therefore, the non-working part of the coil is less, the copper loss is reduced, and the efficiency of the motor is improved.

[0054] The above are preferred embodiments of the application, which do not limit the protection scope of the application. Therefore, equivalent changes made on the basis of the structure, shape, and principle of the application should be covered by the protection scope of the application.
