Description

Technical Field

[0001] This utility model relates to the field of amorphous motor technology, specifically a dual-stator amorphous motor. Background Technology

[0002] Amorphous motors are motors that use amorphous materials as their core, combining high efficiency, environmental friendliness, and energy saving. These motors use amorphous materials instead of traditional silicon steel sheets, exhibiting high permeability and low hysteresis loss, enabling more effective utilization of magnetic fields and thus improving the motor's output power and power factor. To achieve even higher output power and speed, amorphous motors often employ a dual-stator design. In the prior art, patent publication number CN 218387033 U discloses a dual-stator motor, including a motor body with a drive shaft running through it; several fixing ribs are arrayed on the sidewalls of the motor body, forming heat dissipation grooves between adjacent ribs; and a bracket connected to the fixing ribs, with the ends of the ribs connected to the bracket. Although a dual-stator design is used, heat dissipation through heat dissipation grooves alone is slow during operation. Even with cooling fans to force airflow for heat dissipation, the heat dissipation location is not accurate enough, increasing the probability of excessively high internal motor temperatures. Utility Model Content

Both the heat sink 1 and the heat sink 2 are hollow sheets and are connected to the circulating inner shell. Through the cooperation of the heat sinks and the circulating inner shell, the air inside the dual-stator amorphous motor is guided to circulate along a specified trajectory, accurately guiding the air at the heat-generating location of the dual-stator amorphous motor to the hollow heat sink for heat dissipation. This makes the heat dissipation location more accurate, reduces the probability of excessively high internal temperature of the dual-stator amorphous motor, and improves the heat dissipation efficiency of the dual-stator amorphous motor.

The end of heat sink two away from the motor shaft is connected to the confluence cavity on the outer edge of the guide plate, and the end of heat sink two near the motor shaft is connected to the air duct in the middle of the guide plate, guiding air to circulate inside the motor.

[0009] Furthermore, the heat dissipation mechanism also includes a fan blade, which is disposed at the rear end of the outer arc surface of the motor shaft. The fan blade is rotatably connected to the air intake cavity in the middle of the guide plate to provide power for the circulation of air inside the motor.

[0010] Furthermore, the rear end of the outer arc surface of the motor housing is provided with air inlets, and the rear side of the motor housing is provided with air outlets. Both the air inlets and outlets are installed in conjunction with the heat sink to provide space for forced airflow.

[0011] Furthermore, the heat dissipation mechanism also includes a second fan blade, which is disposed at the rear end of the motor shaft. The second fan blade is located between the second heat sink and the rear inner wall of the motor housing, providing power for the forced flow of external air.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This dual-stator amorphous motor has the following advantages:

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6This embodiment provides a technical solution: a dual-stator amorphous motor, including a motor housing 1, a motor shaft 2 rotatably connected to the front end of the motor housing 1 via a bearing, an amorphous rotor 3 located in the middle of the outer arc surface of the motor shaft 2, and two amorphous stators 4 inside the motor housing 1. The dual-stator design can provide higher output power and speed under the same power consumption. The motor core is made of amorphous material, such as amorphous alloy, which has the characteristics of high magnetic permeability and low energy loss. A junction box is provided on the surface of the motor housing 1, and the output end of the junction box is electrically connected to the input end of the coil of the amorphous stator 4.

Both heat sink 51 and heat sink 57 are hollow sheets and are connected to the circulating inner shell 52. The heat dissipation mechanism 5 also includes a flow guide plate 521 and a flow guide ring 522 in the circulating inner shell 52. The flow guide plate 521 is disposed at the rear end of the inner arc surface of the motor housing 1, and the flow guide ring 522 is disposed at the front end of the inner arc surface of the motor housing 1. Amorphous stators 4 are disposed on the inner arc surface of the flow guide ring 522. Heat sink 51 passes through the outer arc surface of the motor housing 1. The through hole is connected to the guide ring 522. The rear end of the guide ring 522 is connected to the confluence cavity on the outer edge of the guide disk 521. The end of the heat sink 57 away from the motor shaft 2 is connected to the confluence cavity on the outer edge of the guide disk 521, and the end of the heat sink 57 near the motor shaft 2 is connected to the air intake cavity in the middle of the guide disk 521. The heat dissipation mechanism 5 also includes a first suction hole 54 and a second suction hole 55. The first suction hole 54 is respectively located at the front end of the inner arc surface of the guide ring 522 and is installed with the bearing of the motor shaft 2. The second suction hole 55 is respectively located in the middle of the inner arc surface of the guide ring 522 and is installed with the amorphous stator 4. Hot air from the bearing of the motor shaft 2 enters the interior of the guide ring 522 through the first suction hole 54. Air surrounding the stator 4 enters the guide ring 522 through the second air intake 55. The hot air entering the guide ring 522 is dispersed into the heat sink 51. Utilizing the heat conduction of the heat sink 51, heat is transferred to the naturally flowing air outside. After being cooled by the heat sink 51, the air flows into the confluence cavity at the outer edge of the guide plate 521. Guided by the guide plate 521, the air enters the second heat sink 57. Under the heat conduction of the second heat sink 57, heat is transferred to the forced airflow outside. The air, after secondary cooling by the second heat sink 57, leaves the second heat sink 57 and enters the air intake cavity in the middle of the guide plate 521. The air then returns to the interior of the circulation inner shell 52. The heat dissipation mechanism 5 also includes a guide plate 56. The airflow guides 56 are respectively located on the inner arc wall of the airflow guide ring 522, and the airflow guides 56 are respectively located in front of the second air intake 55. The airflow guides 56 are respectively located inside the first heat sink 51, guiding the air inside the airflow guide ring 522 to disperse into the first heat sink 51. The heat dissipation mechanism 5 also includes a fan blade 58, which is located at the rear end of the outer arc surface of the motor shaft 2. The fan blade 58 is rotatably connected to the air intake cavity in the middle of the airflow guide plate 521, providing power for the circulation of air inside the inner casing 52. The rear end of the outer arc surface of the motor casing 1 is provided with an air inlet 6, and the rear side of the motor casing 1 is provided with an air outlet 7. The air inlet 6 and the air outlet 7 are both installed in conjunction with the second heat sink 57. The heat dissipation mechanism 5 also includes a second fan blade 53, which is located at the rear end of the motor shaft 2.Fan blade 53 is located between heat sink 57 and the rear inner wall of motor housing 1. Motor shaft 2 drives fan blade 53 to rotate, forcibly guiding external air into the rear end of motor housing 1 through air inlet 6, and finally expelling it through air outlet 7, thus forcibly guiding the flow of external air.

[0024] The working principle of the dual-stator amorphous motor provided by this utility model is as follows: During the use of the dual-stator amorphous motor, current passes through the coils of the two amorphous stators 4 respectively, generating a rotating magnetic field, which drives the amorphous rotor 3 to rotate the motor shaft 2, thus enabling the dual-stator amorphous motor to work. During operation, the motor shaft 2 drives the fan blades 58 to rotate, providing power for the airflow inside the circulation inner shell 52. The hot air at the bearing of the motor shaft 2 enters the guide ring 522 through the suction hole 54, and the air around the amorphous stators 4 enters the guide ring 522 through the suction hole 55, accurately dissipating heat from the heat-generating parts of the dual-stator amorphous motor. The hot air entering the guide ring 522 is dispersed into the heat sink 51 under the guidance of the guide plate 56, utilizing the heat conduction effect of the heat sink 51. The heat is transferred to the naturally flowing air outside. After being cooled by the heat sink 51, the air flows into the confluence cavity on the outer edge of the guide plate 521. Under the guidance of the guide plate 521, the air enters the interior of the heat sink 57. At this time, the motor shaft 2 drives the fan blade 53 to rotate, forcibly guiding the external air from the air inlet 6 into the rear end of the motor housing 1, and finally out from the air outlet 7. Under the heat conduction of the heat sink 57, the heat is transferred to the external forced airflow. The air that has been cooled by the heat sink 57 leaves the heat sink 57 and enters the air intake cavity in the middle of the guide plate 521. Under the guidance of the fan blade 58, the air returns to the interior of the circulation inner shell 52, which efficiently and accurately cools the interior of the dual-stator amorphous motor and prevents external dust from entering the interior of the dual-stator amorphous motor.
