Description

Technical Field

[0001] This utility model relates to the field of three-phase torque motor technology, specifically a three-phase torque motor. Background Technology

[0002] A three-phase motor is a type of motor in which, when three-phase alternating current is applied to the three-phase stator windings (each phase differing by 120 electrical degrees), a rotating magnetic field is generated. This rotating magnetic field cuts the rotor windings, thereby inducing current in the rotor windings (the rotor windings are closed circuits). The current-carrying rotor conductors generate electromagnetic force under the action of the stator rotating magnetic field, thus forming an electromagnetic torque on the motor shaft, driving the motor to rotate, and the direction of motor rotation is the same as the direction of the rotating magnetic field.

[0003] The existing three-phase torque motors have the following drawbacks during use: the three-phase torque motors generate a lot of heat during operation. The heat dissipation mechanism of the existing three-phase torque motors mainly relies on the heat dissipation fins on the outside for natural heat dissipation, or on the high-speed fan connected to the shaft for heat dissipation. The heat inside the three-phase torque motor is dissipated by the rotation of the high-speed fan, which has low heat dissipation efficiency. Therefore, this application proposes a new type of three-phase torque motor. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is: a three-phase torque motor, including: a body and a heat dissipation mechanism, wherein the body includes a motor body, a base fixed to the bottom of the motor body, and heat dissipation fins fixed in a ring array on the outer side of the motor body.

[0006] The heat dissipation fins include a main heat dissipation fin fixed on the outer side of the motor body and multiple fins fixed on both sides of the main heat dissipation fin. The top of the main heat dissipation fin has a through hole that connects to the inner cavity of the motor body.

[0007] The heat dissipation mechanism includes an annular shell sleeved on the outside of the heat dissipation fins, a tube fixed to the inner wall of the annular shell with one side attached to the end of the motor body, a high-speed fan installed on the inner wall of the tube, a guide shell fixed to one side of the annular shell, and a dustproof net sleeved on the outside of the annular shell.

[0008] In a preferred embodiment, the present invention can be further configured such that: air holes are arranged in a ring array on one side of the motor body.

[0009] In a preferred embodiment, the present invention can be further configured such that: slots are arranged in a ring array on the outer surface of the annular shell, the heat dissipation fins are fitted into the slots, and the top of the heat dissipation fins is located inside the slots.

[0010] In a preferred embodiment, the present invention can be further configured such that: ear plates are fixed on both sides of the annular shell, and bolts pass through the ear plates to fix the annular shell to the base.

[0011] In a preferred embodiment, this invention can be further configured such that an air duct is formed between adjacent heat dissipation fins and the annular shell.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, a heat dissipation mechanism is provided, which consists of an annular shell, a tube body, a high-speed fan, and a guide shell. The annular shell is fitted onto the heat dissipation fins on the outside of the motor body. This arrangement creates an airflow channel between adjacent heat dissipation fins. Meanwhile, the tube body is attached to the side of the motor body with an air vent. During operation, the high-speed fan rotates, drawing out hot air from the inner cavity of the motor body and blowing it into the guide shell. Under the action of the guide shell, the high-speed airflow enters the airflow channel formed by the annular shell and adjacent heat dissipation fins, which can quickly remove the heat from the heat dissipation fins, improving the heat dissipation efficiency of the three-phase torque motor. Moreover, the high-speed fan is powered independently and is not affected by the speed of the three-phase torque motor, ensuring stable and high-speed exhaust.

[0014] 2. In this utility model, the heat dissipation fins on the outer side of the motor body consist of a main heat dissipation fin and multiple fins symmetrically fixed on both sides of the main heat dissipation fin. This effectively increases the heat dissipation area of ​​the heat dissipation fins, allowing more heat to be carried away when high-speed air passes through, further improving heat dissipation efficiency. In addition, through holes communicating with the inner cavity of the motor are opened on each heat dissipation fin, serving as air inlets for the inner cavity of the motor body. This design allows cold air from the outside to enter the inner cavity of the motor body evenly, ensuring uniform air circulation within the inner cavity of the motor body. Furthermore, a dustproof net is installed on the outer side of the annular shell, effectively preventing dust from entering the inner cavity of the motor body through the through holes, further enhancing practicality.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example 1

[0026] Combination Figure 1-6 As shown, this embodiment provides a three-phase torque motor, including: a body 100 and a heat dissipation mechanism 200.

[0027] The body 100 includes a motor body 110, a base 120 fixed to the bottom of the motor body 110, and heat dissipation fins 130 fixed in a ring array on the outer side of the motor body 110.

[0028] The motor body 110 serves as a drive source for driving external equipment. A ring array of air vents 111 is provided on one side of the motor body 110 to facilitate the exhaust of hot air from the inner cavity of the motor body 110. The base 120 is used to fix the motor body 110 and facilitates the installation of the motor body 110 on the equipment.

[0029] The heat dissipation fins 130 can conduct heat out of the inner cavity of the motor body 110 and exchange heat with the outside air to achieve heat dissipation of the motor body 110. The heat dissipation fins 130 include a main heat dissipation fin 131 fixed on the outer surface of the motor body 110 and multiple fins 132 fixed on both sides of the main heat dissipation fin 131. This configuration effectively increases the heat dissipation area of ​​the heat dissipation fins 130, allowing more heat to be carried away when high-speed air passes through, thus improving heat dissipation efficiency. In addition, a through hole 1311 is opened at the top of the main heat dissipation fin 131 to connect to the inner cavity of the motor body 110. This configuration allows the outside cold air to enter the inner cavity of the motor body 110 evenly, ensuring the uniformity of air circulation in the inner cavity of the motor body 110 and preventing airflow from circulating only in a single part of the inner cavity of the motor.

[0030] The heat dissipation mechanism 200 is used to dissipate heat from the motor body 110, including an annular shell 210 sleeved on the outside of the heat dissipation fins 130, a tube 220 fixed on the inner wall of the annular shell 210 and with one side close to the end of the motor body 110, a high-speed fan 230 installed on the inner wall of the tube 220, a guide shell 240 fixed on one side of the annular shell 210, and a dustproof net 250 sleeved on the outside of the annular shell 210.

[0031] The outer surface of the annular shell 210 has slots 211 arranged in a ring array. The heat dissipation fins 130 are fitted into the slots 211, and the top of the heat dissipation fins 130 is located inside the slots 211 to avoid mutual interference between air intake and exhaust. Through this arrangement, an air duct is formed between adjacent heat dissipation fins 130 and the annular shell 210, which facilitates the passage of high-speed airflow to remove the heat on the heat dissipation fins 130.

[0032] In addition, ear plates 212 are provided on both sides of the bottom of the annular shell 210. Bolts pass through the ear plates 212 to fix the annular shell 210 to the base 120, ensuring the stability of the annular shell 210 and facilitating the installation and disassembly of the annular shell 210.

[0033] The tube body 220 is fixed inside the annular shell 210, with its end attached to the end of the air vent 111 of the motor body 110. The high-speed fan 230 is installed on the inner wall of the tube body 220 and is independently set up and powered by an independent power supply. It is used to extract the hot air from the inner cavity of the motor body 110 and blow it into the air guide shell 240.

[0034] The airflow guide shell 240 is used to guide high-speed airflow into the air duct between the adjacent heat sink fins 130 and the annular shell 210. The dustproof net 250 can prevent dust from entering the inner cavity of the motor body 110 through the through hole 1311 on the main heat sink 131.

[0035] The working principle and usage process of this utility model are as follows: When in use, the high-speed fan 230 rotates, drawing out the hot air inside the motor body 110 through the air hole 111 and blowing it into the guide shell 240. Under the action of the guide shell 240, the high-speed airflow enters the air duct formed by the shell and the adjacent heat dissipation fins 130, which can quickly carry away the heat on the main heat dissipation fins 131 and fins 132, and finally discharge it into the external environment. After the high-speed fan 230 discharges the hot air inside the motor, the air pressure inside the motor decreases. At this time, the cold air from the outside enters the motor evenly through the through hole 1311 on the main heat dissipation fin 131, absorbs heat, and is then drawn out by the high-speed fan 230, forming a circulation, ensuring efficient heat dissipation of the motor body 110.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
