Small-frame high-power motor

Abstract

This utility model discloses a small-base, high-power motor, belonging to the field of motor technology. It solves the problem of heat accumulation inside the casing of existing motors during operation, hindering rapid heat dissipation. Its external structure includes an outer shell, a front cover, a rear cover, and a shaft. The shaft is located inside the outer shell, and support seats are provided at both ends of the bottom of the outer shell. A heat dissipation assembly is provided on the outer surface of the outer shell. Heat is absorbed inside the outer shell by heat-conducting fins, and air is blown into the mounting tube and annular plate by a cooling fan. The air is then discharged through the air outlet and circulates between adjacent heat-conducting fins, carrying away heat from the area around the fins and accelerating their heat dissipation rate. This, in turn, dissipates heat from the outer shell, preventing heat buildup inside and improving the overall heat dissipation efficiency, thus extending the motor's lifespan.

Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a small-frame, high-power motor. Background Technology

[0002] Small-frame, high-power motors refer to motors that can output high power in a relatively small frame size. They typically use high-magnetic-energy materials, high-performance materials, and precision manufacturing processes. Through reasonable circuit design and control, they achieve high-efficiency energy conversion, converting more electrical energy into mechanical energy, thereby outputting high power in a small volume.

[0003] A search revealed that patent application number 202421045301.1 discloses a high-power asynchronous motor with an anti-vibration structure, relating to the field of motor anti-vibration technology. The motor includes a motor body, a motor base frame, and an anti-vibration structure. The anti-vibration structure includes a support member, a base, a support plate, and a damper. The support member includes a support horizontal plate and a support vertical plate. The top two sides of the support vertical plate are machined with a second inclined surface, and the other side of the support plate is machined with a first inclined surface. Although this high-power asynchronous motor with an anti-vibration structure utilizes a base to mount the anti-vibration structure between the bottoms of two motor base frames, causing the bottom of the support components on the anti-vibration structure to protrude from the bottom surface of the motor base frame, facilitating the damping of vibrations generated during motor operation, the motor's casing continuously generates and accumulates heat during operation, and rapid heat dissipation is difficult. As operating time increases, if this heat cannot be effectively dissipated in a timely manner, it will not only lead to a significant increase in the internal temperature of the motor, accelerating the aging of insulation materials and reducing motor operating efficiency, but may also cause bearing lubrication failure, winding short circuits, and other faults, seriously threatening the reliability and service life of the motor, and even potentially affecting the stable operation of the entire system.

[0004] Therefore, we propose a small-frame, high-power motor. Utility Model Content

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a small-base high-power motor, the external structure of which includes an outer shell, a front cover, a rear cover and a shaft. The left and right ends of the outer shell are respectively equipped with the front cover and the rear cover. The shaft is provided inside the outer shell and extends to the left side of the front cover. Support seats are provided at both the left and right ends of the bottom of the outer shell. The outer surface of the housing is provided with a heat dissipation component; The heat dissipation assembly includes a heat-conducting component disposed on the outer surface of the outer shell. A hollow annular plate is fixedly fitted onto the outer surface of the outer shell on the right side of the heat-conducting component. The left side of the annular plate has evenly distributed air outlet holes. An installation tube communicating with its inner cavity is fixedly installed on the top surface of the annular plate. A cooling fan is fixedly installed on the inner wall of the top end of the installation tube.

[0007] Preferably, the heat-conducting component includes two heat-conducting elements symmetrically distributed on the outer surface of the outer shell. Each heat-conducting element includes a heat-conducting sheet, a connecting lug, and two semi-circular connecting plates. An array of heat-conducting sheets is disposed between the two connecting plates. The heat-conducting sheets are made of copper and are in contact with the arc surface of the outer shell. Heat inside the outer shell is conducted into the heat-conducting sheets.

[0008] Preferably, the two ends of the heat-conducting sheet are respectively fixedly installed on the side wall of the connecting plate on the same side. The side wall of the connecting plate is provided with ventilation holes that are distributed in an array and staggered with the heat-conducting sheets. The ventilation holes are provided to facilitate the flow of air between adjacent heat-conducting sheets.

[0009] Preferably, both ends of the connecting plate are fixedly installed with connecting ears, and the sidewalls of the connecting ears are provided with connecting holes. Adjacent connecting ears are connected by bolts and nuts. The connecting ears are provided to facilitate fixing two heat-conducting components together.

[0010] Preferably, the support base includes a support block and a support rod. The support block is fixedly installed on the arc surface of the outer shell, and the support rod is provided on the bottom surface of the support block. The support block and the support rod are integrally formed. Mounting holes are provided at both ends of the support rod. The outer shell is supported by the support block and the support rod, and the support base can be fixed in a specific installation position by using bolts passing through the mounting holes.

[0011] This utility model provides a small-frame, high-power motor. It has the following advantages: 1. This small-base, high-power motor absorbs heat from inside the outer casing through heat-conducting plates. A cooling fan blows air into the mounting tube and annular plate, and the air is then discharged through the air outlet and flows between adjacent heat-conducting plates through the ventilation holes. This removes heat from the area around the heat-conducting plates, accelerating the heat dissipation rate of the heat-conducting plates and thus dissipating heat from the outer casing. This prevents heat buildup inside the outer casing, improves the heat dissipation efficiency of the outer casing, and helps extend the service life of the motor. It solves the problem in existing devices where heat accumulates inside the motor casing during operation, making it difficult to dissipate heat quickly. 2. This small-base high-power motor can be installed on the outer surface of the outer shell by placing two heat-conducting components on the outer surface of the outer shell, and then fixing the two adjacent connecting ears together with bolts and nuts. This achieves the purpose of easy installation on the outer surface of the outer shell and is simple and convenient to use. Attached Figure Description

The front cover 2 and the rear cover 3 are respectively installed at the left and right ends of the outer shell 1. The shaft 4 is provided inside the outer shell 1, and the shaft 4 extends to the left side of the front cover 2. Support seats 5 are provided at both the left and right ends of the bottom of the outer shell 1. A heat dissipation assembly 6 is provided on the outer surface of the outer shell 1. The heat dissipation assembly 6 includes a heat-conducting component 61 provided on the outer surface of the outer shell 1. An annular plate 62, which is fixedly fitted on the outer surface of the outer shell 1 and is hollow inside, is provided on the right side of the heat-conducting component 61. The left side of the annular plate 62 has evenly distributed air outlet holes 63. The top surface of the annular plate 62 is fixedly installed. There is an installation tube 64 connected to its inner cavity. A cooling fan 65 is fixedly installed on the inner wall of the top of the installation tube 64. The heat is absorbed by the heat conduction plate 612. The cooling fan 65 can blow air into the installation tube 64 and the annular plate 62. Then the air is discharged through the air outlet 63 and flows between two adjacent heat conduction plates 612 through the ventilation hole 614. It can carry away the heat around the heat conduction plate 612, so as to accelerate the heat dissipation rate of the heat conduction plate 612 and then dissipate heat from the outer shell 1. This can prevent heat accumulation inside the outer shell 1 and achieve the purpose of improving the heat dissipation efficiency of the outer shell 1, which is beneficial to increasing the service life of the motor.

[0016] Example 2: like Figure 1-4 As shown: The heat-conducting component 61 includes two heat-conducting elements symmetrically distributed on the outer surface of the outer casing 1. Each heat-conducting element includes a heat-conducting plate 612, a connecting lug 613, and two semi-circular connecting plates 611. An array of heat-conducting plates 612 is arranged between the two connecting plates 611. The heat-conducting plates 612 are made of copper and are in contact with the arc surface of the outer casing 1. The two ends of the heat-conducting plates 612 are respectively fixedly installed on the side wall of the connecting plate 611 on the same side. The side wall of the connecting plate 611 has openings that correspond to the array of heat-conducting plates 612. The ventilation holes 614 are staggered. Both ends of the connecting plate 611 are fixedly installed with connecting ears 613. Connecting holes are opened on the side wall of the connecting ears 613. Adjacent connecting ears 613 are connected by bolts and nuts. By fitting two heat-conducting components onto the outer surface of the outer shell 1 respectively, and then fixing the two adjacent connecting ears 613 together with bolts and nuts, the two heat-conducting components can be installed on the outer surface of the outer shell 1. This achieves the purpose of facilitating the installation of 31 on the outer surface of the outer shell 1, making it simple and convenient to use.

The support rod 52 is provided on the bottom surface of the support block 51. The support block 51 and the support rod 52 are integrally formed. Mounting holes 53 are provided at both ends of the support rod 52. The outer shell 1 is supported by the support block 51 and the support rod 52. The support base 5 can be fixed in a specific installation position by using bolts through the mounting holes 53.

[0018] The working principle and usage process of this utility model: The heat inside the front cover 2 of this small base high-power motor is conducted to the heat conduction plate 612. When the cooling fan 65 is started, air can be blown into the mounting tube 64 and the annular plate 62. Then the air is discharged through the air outlet 63 and flows between two adjacent heat conduction plates 612 through the ventilation hole 614. This can remove the heat around the heat conduction plate 612, so as to accelerate the heat dissipation rate of the heat conduction plate 612, and then dissipate heat from the outer shell 1. When assembling the heat-conducting component 61, the two heat-conducting components are respectively fitted onto the outer surface of the outer shell 1, and then the two adjacent connecting ears 613 are fixed together with bolts and nuts, so that the two heat-conducting components can be installed on the outer surface of the outer shell 1.
