Description

Technical Field

[0001] This utility model relates to the field of hollow cup motor technology, specifically a low-consumption, high-energy hollow cup motor. Background Technology

[0002] A coreless motor is a type of electric motor in which the coil is shaped like a cup. It has sensitive and convenient control characteristics and stable operation characteristics, and has been widely used in many fields. Coreless motors are divided into brushed and brushless types. However, existing coreless motors still have certain defects in use. The limit sleeve is often welded to the inner wall of the motor, making it inconvenient to adjust the distance between the limit sleeve and the rotor. The working range is small and the use is inconvenient, which greatly reduces the accuracy of the coreless motor.

[0003] Patent CN216490117U discloses a high-precision hollow cup motor. By setting a docking ring, the precision of the hollow cup motor can be greatly improved. In use, the hydraulic device set inside the docking ring and the hydraulic fixing rod set at one end of the hydraulic device can drive the hydraulic fixing rod to move under the action of the hydraulic device. By moving the two hydraulic fixing rods set inside the docking ring relative to each other, the connected object of the hollow cup motor can be fixed, thereby enabling the rotor inside the hollow cup motor to run stably. In this way, the precision of the hollow cup motor can be improved indirectly.

[0004] In the aforementioned patent, the hollow cup motor solves the problems mentioned above. However, the hollow cup motor in this patent still has the following problems: during the operation of the hollow cup motor, heat dissipation is required through the heat dissipation grooves opened on the outside of the hollow cup motor body. However, the hollow cup motor body and the welding plate are sealed, resulting in the motor's interior being sealed. This prevents the heat generated during the operation of the hollow cup motor from being dissipated quickly, accelerating the rise in the internal temperature of the hollow cup motor. This will aggravate the loss of electrical energy inside the motor and affect the electrical energy conversion rate of the hollow cup motor.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing hollow cup motor structure. Utility Model Content

[0006] The purpose of this utility model is to provide a low-consumption, high-energy hollow cup motor to solve the problem mentioned in the background art that the hollow cup motor body and the welding plate are sealed together, resulting in a sealed state inside the motor. This prevents the heat generated by the hollow cup motor during operation from being dissipated quickly, accelerates the rise in the internal temperature of the hollow cup motor, and thus aggravates the loss of internal electrical energy and affects the electrical energy conversion rate of the hollow cup motor.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-consumption, high-energy hollow cup motor, comprising a housing and an upper end cover that is snapped onto the upper end of the housing;

[0008] The lower end of the housing is fitted with a lower end cover, and a connector is fixedly installed at the lower end of the lower end cover. A rotating shaft is rotatably installed inside the housing. A connecting plate is fixedly installed on the outer side of the rotating shaft through a commutator, and a cup-shaped coil located inside the housing is fixedly installed on the outer side of the connecting plate.

[0009] A mating flange is fixedly installed on the upper end of the lower end cover, and a permanent magnet is engaged on the upper end of the mating flange. Dustproof arc plates are engaged inside the upper and lower end covers.

[0010] Preferably, an arc-shaped magnetic strip is fixedly installed at one end of the dustproof arc plate near the outer shell, and the arc-shaped magnetic strip is in close contact with the upper end cover and the lower end cover respectively.

[0011] Preferably, two sets of the dustproof arc plate and the arc-shaped magnetic strip are respectively provided inside the upper end cover and the lower end cover, and the two sets of dustproof arc plates and arc-shaped magnetic strips are arranged symmetrically about the vertical central axis of the rotation axis.

[0012] Preferably, the outer side of the rotating shaft is provided with an inner shell that is fixedly installed with the docking flange, and the inner shell is located inside the permanent magnet.

[0013] Preferably, a heat dissipation ring is bonded to the outer side of the outer shell, and a heat dissipation plate is fixedly installed at equal angles on the outer side of the heat dissipation ring. Furthermore, the heat dissipation plate and the heat dissipation ring have internal slots for heat dissipation.

[0014] Preferably, the upper end cover and the lower end cover are rotatably connected to the rotating shaft, and the permanent magnet outside the rotating shaft is located inside the cup-shaped coil, and the thickness of the permanent magnet is greater than the thickness of the cup-shaped coil.

[0015] Preferably, the two sets of dustproof arc plates inside the upper end cover and the two sets of dustproof arc plates inside the lower end cover are arranged to overlap, and the interior of the dustproof arc plates is made of high composite polyester material.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By installing a dustproof arc plate and an arc-shaped magnetic strip on the outside of the hollow cup motor, the high-temperature gas inside the hollow cup motor can be quickly discharged, reducing the rate of temperature rise inside the hollow cup motor and preventing dust from entering the motor. At the same time, the dustproof arc plate can be removed for cleaning through the arc-shaped magnetic strip, ensuring the ventilation effect of the hollow cup motor, improving the conversion of electrical energy into kinetic energy inside the hollow cup motor, and achieving the goal of low consumption and high energy.

[0018] 2. Furthermore, by setting up heat dissipation rings and heat dissipation plates, the heat dissipation rings and heat dissipation plates can absorb the heat inside the casing, and at the same time realize the heat transfer between the heat dissipation rings and heat dissipation plates and the air. At the same time, the installation position of the heat dissipation rings and heat dissipation plates can be adjusted according to specific conditions to achieve rapid cooling inside the motor, further ensuring the low-consumption and high-energy effect of the motor.

[0019] 3. Furthermore, the motor has a simple internal structure, allowing for rapid production and use, resulting in good economic benefits and broad application prospects. Attached Figure Description

[0028] 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.

[0029] In a specific embodiment, such as Figures 1-7The basic cooling process of the hollow cup motor is shown in the figure.

[0030] The housing 1 has an upper cover 2 that is snapped onto its upper end; the lower end of the housing 1 has a lower cover 3 that is snapped onto its lower end, and a connector 4 is fixedly installed at the lower end of the lower cover 3. A rotating shaft 5 is rotatably mounted inside the housing 1, and a connecting plate 7 is fixedly mounted on the outer side of the rotating shaft 5 via a commutator 6. A cup-shaped coil 8 located inside the housing 1 is fixedly mounted on the outer side of the connecting plate 7. A mating flange 9 is fixedly installed at the upper end of the lower cover 3, and a permanent magnet 10 is snapped onto the upper end of the mating flange 9. The upper and lower cover 3 are internally connected... The assembly is equipped with a dustproof arc plate 14. An arc-shaped magnetic strip 15 is fixedly installed at one end of the dustproof arc plate 14 near the outer shell 1. The arc-shaped magnetic strip 15 is in close contact with the upper end cover 2 and the lower end cover 3 respectively. Two sets of dustproof arc plates 14 and arc-shaped magnetic strips 15 are respectively arranged inside the upper end cover 2 and the lower end cover 3. The two sets of dustproof arc plates 14 and arc-shaped magnetic strips 15 are symmetrically arranged about the vertical central axis of the rotating shaft 5. An inner shell 11 is fixedly installed on the outer side of the rotating shaft 5 and is located inside the permanent magnet 10.

[0031] When using this low-power, high-energy hollow cup motor, the positive and negative wire groups of the external connector 4 need to be connected. After connection, the hollow cup motor can be powered and made to work. During the operation of the hollow cup motor, the cup-shaped coil 8 will rotate with the rotating shaft 5, and the commutator 6 and the connecting plate 7 will rotate synchronously with the rotating shaft 5. During the operation of the hollow cup motor, heat will be generated, which will reduce the efficiency of the conversion of electrical energy into kinetic energy inside the hollow cup motor. The increase in internal temperature of the motor will lead to an increase in the resistance of its internal electrical structure, which will increase the conversion of electrical energy into heat energy. According to the law of conservation of energy, the efficiency of the conversion of electrical energy into kinetic energy will naturally decrease, increasing the energy consumption during the operation of the hollow cup motor.

[0032] The dustproof arc plate 14 allows direct airflow between the two ends of the motor and the outside, satisfying the conditions for air flow inside and outside the motor. During the rotation of the motor, the cup-shaped coil 8 rotates, thereby driving the airflow inside the motor. This airflow between the inside and outside of the motor allows the hot air inside the hollow cup motor to be discharged through the dustproof arc plate 14 inside the upper end cover 2 and the lower end cover 3, allowing ambient air to enter the hollow cup motor. This accelerates the heat transfer between the inside and outside of the hollow cup motor, thereby slowing down the rise in the internal temperature of the hollow cup motor and ensuring the efficiency of converting electrical energy into kinetic energy inside the hollow cup motor. This achieves the effect of low energy consumption and high energy efficiency of the hollow cup motor. Furthermore, the dustproof arc plate 14 reduces the entry of dust from the outside air into the motor. The dustproof arc plate 14 and the arc-shaped magnetic strip 15 can be removed to clean the dust adhering to the outside of the dustproof arc plate 14, ensuring the ventilation effect of the dustproof arc plate 14 and thus ensuring the low energy consumption and high energy efficiency of the hollow cup motor.

[0033] In one specific embodiment, such as Figures 1-4 The process of heat dissipation on the outside of the hollow cup motor is shown in the figure.

[0034] A heat dissipation ring 12 is bonded to the outer side of the outer shell 1, and a heat dissipation plate 13 is fixedly installed at equal angles on the outer side of the heat dissipation ring 12. The heat dissipation plate 13 and the heat dissipation ring 12 have slots for heat dissipation. The upper end cover 2 and the lower end cover 3 are rotatably connected to the rotating shaft 5. The permanent magnet 10 on the outer side of the rotating shaft 5 is located inside the cup-shaped coil 8, and the thickness of the permanent magnet 10 is greater than the thickness of the cup-shaped coil 8. The two sets of dustproof arc plates 14 inside the upper end cover 2 and the two sets of dustproof arc plates 14 inside the lower end cover 3 are arranged overlappingly, and the interior of the dustproof arc plate 14 is made of high composite polyester material.

[0035] Before the low-power, high-energy hollow cup motor can be put into operation, it needs to be fixed in a designated position, and the heat dissipation ring 12 needs to be installed on the outside of the outer casing 1. Simultaneously, the heat dissipation plate 13 must not interfere with the normal operation of the hollow cup motor. During operation, heat transfer between the outer casing 1 and the outside environment is necessary to ensure effective heat dissipation. After the heat dissipation ring 12 and heat dissipation plate 13 are installed, the heat transfer between the inside and outside of the hollow cup motor is accelerated. The heat dissipation ring 12 absorbs heat from inside the outer casing 1, and the heat dissipation plate 13 absorbs heat from inside the heat dissipation ring 12 again. Then, heat transfer occurs between the heat dissipation plate 13 and the air, accelerating the rapid heat transfer within the outer casing 1. This results in a rapid decrease in the internal temperature of the hollow cup motor, reducing current loss due to temperature increases, ensuring the low-power, high-energy performance of the hollow cup motor, and increasing its overall practicality.
