Description
Technical Field
[0001] The utility model relates to an electric motor, in particular to a self-cooling electric motor with double flanges, double shaft extensions and high efficiency in wind collection. Background Art
[0002] With the rapid development of industrial automation and mechanical equipment, the performance and efficiency of electric motors, as the core components of drive equipment, are particularly important.
[0003] Traditional electric motors have limitations in heat dissipation and structural design. With typical self-cooling methods, heat generated internally during motor operation is transferred to the surface of the casing, where it is removed by airflow generated by a fan. The fan, typically mounted on the motor shaft, rotates as the motor rotates, removing heat through convection. However, airflow away from the fan diffuses outward with increasing distance, preventing effective convection, resulting in higher motor temperature rise and lower efficiency.
[0004] At the same time, due to the lack of reasonable space control when installing the fan on the end cover of the traditional motor, both the end cover and the fan occupy too much axial space. Especially when used on a double-axle motor, the two directly lead to an increase in the motor shaft length, affecting the output torque of the motor. Generally speaking, under the same conditions, the shorter the motor shaft, the greater the output torque. Utility Model Content

The side flange is set to be flat, and the fan outer cover is provided with a wind cover, and the wind cover is connected to the flange on the same side. An air collecting duct is installed between the flanges at both ends, and a heat dissipation channel is formed between the air collecting duct and the casing. The heat dissipation channel connects the air outlet and the air inlet and outlet channels on the flange at one end where the fan is located.
[0007] Furthermore, a plurality of air inlet and outlet channels are provided on the flange at one end where the fan is located, and the plurality of air inlet and outlet channels are all connected to the heat dissipation channel.
[0008] Furthermore, the air collecting tube is fixedly connected to the heat dissipation ribs arranged along the axial direction outside the casing by screws.
[0009] Furthermore, the wind collecting tube is fixedly connected to a positioning platform provided on a flange at one end where the fan is located through its end wall.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0029] Embodiment 1;
[0030] Figure 1 As shown, this embodiment discloses a double-flange double-axle extension wind collection high-efficiency self-cooling motor, including a motor body, and also includes flanges installed at both ends of the casing of the motor body. In this embodiment, the flanges at both ends of the casing 1 include Figure 5 The front flange 2 and Figure 6 The rear flange 3 shown in FIG. 1 shows the motor's rotating shaft 4 extending from the front flange 2 and rear flange 3, respectively. The rear flange 3 is configured to be flat, and a fan 5 is mounted on the rotating shaft extension on one side of the rear flange 3. The fan 5 is covered by a wind shield 6, which is screwed to the flange on the same side. A wind duct 7 is mounted between the front flange 2 and the rear flange 3. In this embodiment, the wind duct is fixedly connected to the positioning platform 16 provided on the rear flange 3 via its end wall. Thus, a heat dissipation channel 9 is formed between the wind duct 7 and the housing 1. The heat dissipation channel 9 connects the air outlet 11 and the air inlet and outlet channels on the rear flange 3. The wind force generated by the fan 5 during rotation is pressurized within the wind shield 6, enters the heat dissipation channel 9 through the air inlet and outlet channels 10, removes heat from the housing 1, and is discharged from the air outlet 11. The purpose of configuring the rear flange 3 to be flat is to fully save the installation space of the fan 5 and shorten the shaft extension length on this side.
[0031] In order to improve the air intake efficiency of the heat dissipation channel 9 , a plurality of air inlet and outlet channels are provided on the rear end flange 3 , and the plurality of air inlet and outlet channels are all connected to the heat dissipation channel.
[0032] The lower edge of the front flange 2 has a downwardly extending air collecting platform 15, forming an air outlet between the air collecting platform 15 and the air collecting tube 7. The air outlet and the heat dissipation channel form a U-shaped circulation channel. The air outlet 11 is formed between the air collecting platform 15 on the front flange 2 and the air collecting tube 7, and the opening of the air outlet faces the rear flange 3. Therefore, the setting of the air outlet forms a detour for the heat dissipating air from the air collecting tube 7. This heat dissipating air can be turned back from the direction of the front flange 2 outside the air collecting tube 7 and blow toward the rear flange 3, which can remove some of the heat from the air collecting tube 7. The combined effect of the heat dissipating air inside and outside the air collecting tube 7 plays a continuous positive feedback role in the heat dissipation of the casing 1, thereby further improving the heat dissipation efficiency.
[0033] Embodiment 2:
[0034] Figure 2 and Figure 3 As shown, this embodiment discloses a dual-flange, dual-extension, air-collecting, and efficient self-cooling motor, comprising a motor body and flanges mounted on both ends of the motor housing. In this embodiment, the flanges at both ends of the housing 1 include a front flange 2 and a rear flange 3. The motor's rotating shaft 4 extends from the front flange 2 and rear flange 3, respectively. A fan 5 is mounted on the shaft extensions of the front flange 2 and rear flange 3. The fan 5 is covered by a wind shield 6, which is screwed to the flanges on the same side. An air collector 7 is mounted between the front flange 2 and rear flange 3. In this embodiment, the air collector 7 is screwed to a heat dissipation rib 8 provided along the axial direction of the housing 1. It should be understood that the wide width of the heat dissipation rib 8 facilitates the provision of screw holes for mounting the screws. Simultaneously, a plurality of heat dissipation ribs 12 are provided along the axial direction of the housing 1. The narrow width of the heat dissipation ribs 12 accelerates heat exchange and removes heat from the housing more quickly. The air outlet and the heat dissipation channel form a U-shaped flow channel, with the air outlet opening facing the rear flange 3.
[0035] Embodiment 3;
[0036] Based on the second embodiment, Figure 4As shown, a wire outlet hole 13 is provided on the rear end flange 3, and the wire outlet hole 13 is also located in a groove 14 provided on the outer side of the rear end flange 3, and the groove 14 is arranged along the radial direction of the rear end flange 3. Therefore, the output wires of the motor are led out through the groove of the rear end flange and fixed to the preset bracket for installing the wind hood with a cable fixing buckle. In this embodiment, the motor is installed on the base, and the base is composed of a foot and a bracket. The terminal block, switch, and protection system of the motor can be installed in the base bracket. The rear flange cover of the motor is connected to the upper plane of the base and locked with bolts. The design of the base allows the terminal block, switch, protection system, etc. to be installed in the base bracket, which is convenient for maintenance and operation. The output wires of the motor are led out through the groove of the rear end cover and fixed to the bracket for installing the wind hood with a cable fixing buckle, ensuring the safety and beauty of the output wires.
[0037] It can be seen from the above embodiments that the motor can achieve double-head installation and double-head shaft output without affecting the self-cooling effect, which directly improves the flexibility of installation and increases the scope of application compared to single-head shaft output. It should be noted that the double-flange double-shaft extended wind collection and efficient self-cooling motor supports vertical and horizontal installation, meeting the needs of different application scenarios.
[0038] In particular, in Example 1, the air collection tube is mounted on a housing with heat dissipation ribs. Tests have shown that the effective utilization rate of air is over 95%, significantly reducing the temperature rise of the motor and improving its operating efficiency. Furthermore, the sleek air collection tube design in the above three embodiments enhances the motor's aesthetic appeal.
[0039] In summary, the double-flange, double-extension, air-collecting, and efficient self-cooling motor has significant technical advantages in improving motor efficiency, reducing temperature rise, enhancing heat dissipation performance, and installation flexibility, providing a more efficient and reliable drive solution for industrial production and automation equipment.
[0040] The above-mentioned implementation manner is not a limitation of the present invention, and the present invention is not limited to the above-mentioned examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
