Description

Technical Field

[0001] The present application relates to the field of motor technology, and in particular to an energy-saving three-phase motor. Background Art

[0002] A three-phase motor is an AC motor driven by three-phase AC power. A three-phase motor is one in which a rotating magnetic field is generated when three-phase AC power is applied to the motor's three-phase stator windings (each phase differs by 120 degrees electrical angle). This rotating magnetic field cuts through the rotor windings to generate electricity.

[0003] Because three-phase motors generate significant heat during operation, poor heat dissipation can affect motor efficiency and even damage the motor. Currently, a common practice is to install heat sinks on the motor's outer wall and a fan on the rotor to achieve air cooling. In winter, due to the lower ambient temperature, three-phase motors need to run for a longer period of time before generating enough heat to dissipate. The fan, mounted on the rotor, rotates, driving the fan and consuming energy. However, during the initial winter startup phase, the motor does not require fan cooling. Therefore, an energy-saving three-phase motor is needed to address this issue. Utility Model Content

Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0026] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0027] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0028] This specific embodiment is an energy-saving three-phase motor, such as Figure 1As shown, it includes a motor 1, a motor rotor 2 is installed on the motor 1, and a third limiting column 201 is symmetrically fixedly connected to the outer wall of one end of the motor rotor 2. A number of heat sinks 104 are fixedly connected to the outer wall of the motor 1, and a control host 101 is installed on the top of the motor 1. A cover plate 102 is screwed to one end of the motor 1, and a number of ventilation holes 107 are opened on the outer wall of the cover plate 102. A limiting hemisphere 103 is fixedly connected to the inner wall of the cover plate 102; a control component, specifically, a motor rotor 2 is installed in the middle of the motor 1, and a number of heat sinks 104 are fixedly connected to the outer wall of the motor 1. The heat sinks 104 are straight plates made of metal, distributed in a circular array, and parallel to the direction of the motor 1. The setting of the heat sink 104 is to increase the heat dissipation area of ​​the motor 1. The control host 101 is installed on the top outer wall of the motor 1. The control host 1 01 can reduce the speed of the motor rotor 2 when the heat of the motor 1 is too high. The cover 102 is screwed to one end of the motor 1 by screws. The cover 102 is a hollow metal cylinder with a seal at one end. Several ventilation holes 107 are opened on the outer wall of the sealed end. The ventilation holes 107 are hexagonal in shape. The limiting hemisphere 103 is fixedly connected to the inner wall of the cover 102 at the end where the ventilation holes 107 are opened. The third limiting column 201 is symmetrically fixedly connected on both sides of the outer wall of the end of the motor rotor 2 close to the cover 102. The third limiting column 201 is a rectangular parallelepiped made of metal and has an arc at the end away from the motor rotor 2. The control component is used to control the rotation of the fan 7 according to the heat of the motor 1. The control component is connected to the motor 1 and the motor rotor 2. By setting the control component, the rotation of the fan 7 can be controlled to achieve the effect of saving energy.

[0029] Reference Figures 2 to 6As shown, the control component includes four clamping frames 105 fixedly connected to the outer wall of one end of the motor 1, the clamping frames 105 are clamped with a control disk 3, the outer wall of the clamping frames 105 is provided with a segmented groove 106, and the interior of the control disk 3 is provided with a mercury injection groove 301. Specifically, the control component includes four clamping frames 105 fixedly connected to the outer wall of one end of the motor 1, and the four clamping frames 105 are distributed in a circular array, wherein the clamping frames 105 are made of metal, have an overall curvature and are composed of three parts: an arc plate, a straight plate and an S-shaped plate. The clamping frames 105 are subjected to force during the clamping process, which will cause the S-shaped plate and the arc plate to cooperate with each other and deform in their respective bending directions. The several segmented grooves 106 on the outer wall of the S-shaped plate in the clamping frames 105 will cause it to be clamped. During the connection process, it deforms in the direction of its own bending. Such a setting can easily clamp the control disk 3 on the clamping frame 105. The control disk 3 is made of metal, and is in the shape of a truncated cone with a curved side wall. The mercury injection groove 301 is opened inside the control disk 3. The mercury injection groove 301 consists of three annular grooves, six cylindrical grooves and twenty-four cylindrical grooves with a curvature. The cylindrical groove penetrates the three annular grooves, and one end of the curved cylindrical groove passes through the annular groove away from the clamping frame 105, and the other end passes through the end of the control disk 3 away from the clamping frame 105. Such a setting allows the metal mercury in the mercury injection groove 301 to circulate with each other. When the control disk 3 is heated, the mercury in the mercury injection groove 301 will expand due to the heat and flow toward the end of the control disk 3 away from the clamping frame 105.

[0030] Reference Figures 2 to 6As shown, a piston column 4 is slidably connected to the inner wall of one end of the mercury injection groove 301, and one end of the piston column 4 is fixedly connected to a fixed plate 401. A first rotating cylinder 5 is rotatably connected to the outer wall of the fixed plate 401. A first limiting column 502 is fixedly connected to the inner wall of the first rotating cylinder 5, and two second limiting columns 501 are fixedly connected to the outer wall of the first rotating cylinder 5. Specifically, the piston column 4 consists of two parts, a rubber cylinder and a metal cylinder. There are a total of twenty-four of them, which are distributed in a circular array. One end of the twenty-four piston columns 4 is slidably connected to the twenty-four piston columns 4 in the mercury injection groove 301. The inner wall of the cylindrical groove with an arc, and the other end thereof is fixedly connected to the outer wall of the same fixed plate 401. The fixed plate 401 is a hollow metal circular plate. A rotating groove 503 is opened on the outer wall of the end of the first rotating cylinder 5 close to the fixed plate 401. The first rotating cylinder 5 is a plastic hollow cylinder. The rotating groove 503 is an annular groove with a "concave" shape in cross section. The fixed plate 401 is rotatably connected to the inner wall of the rotating groove 503. The first limiting post 502 is fixedly connected to the inner wall of the first rotating cylinder 5 close to the fixed plate 401. The first limiting post 50 2 is a rectangular parallelepiped made of plastic, and the two second limiting posts 501 are symmetrically fixedly connected to the two sides of the outer wall of the first rotating cylinder 5. The second limiting posts 501 are rectangular parallelepiped made of plastic, and the outer wall of the two third limiting posts 201 fixedly connected to the motor rotor 2 mentioned above, which are away from the motor rotor 2, fits the outer wall contour of the first rotating cylinder 5. When the motor rotor 2 is rotating, the third limiting posts 201 rotate on the inner wall of the end of the first rotating cylinder 5 away from the fixed plate 401 until the motor 1 heats up. At this time, the control host 101 mentioned above can When the heat reaches a limited temperature, the speed of the motor rotor 2 is reduced. Mercury expands due to the heat, pushing the piston rod 4 toward the first rotating cylinder 5, driving the first rotating cylinder 5 to move in the same direction. The first limiting rod 502 also moves with the displacement of the first rotating cylinder 5 until it moves to the area where the third limiting rod 201 is limited in speed and rotates slowly. At this time, the third limiting rod 201 will drive the first rotating cylinder 5 to rotate while rotating, cooling the motor 1 to the limited temperature of the control host 101, and restoring the speed of the motor rotor 2.

[0031] The second rotating cylinder 6 is slidably connected to the outer wall of the first rotating cylinder 5. A rotating groove 503 is provided on the outer wall of one end of the first rotating cylinder 5. A fan 7 is fixedly connected to one end of the second rotating cylinder 6. Two sliding grooves 601 are provided on the inner wall of the second rotating cylinder 6. Specifically, the inner wall of the second rotating cylinder 6 is slidably connected to the outer wall of the first rotating cylinder 5. The second rotating cylinder 6 is a hollow cylinder made of plastic. Two sliding grooves 601 are symmetrically provided on both sides of the inner wall of the second rotating cylinder 6 close to the first rotating cylinder 5. The inner wall profile of the sliding groove 601 is adapted to the outer wall profile of the second limiting column 501. The second limiting column 501 can slide on the inner wall of the sliding groove 601, and the fan 7 is fixedly connected to the other end of the second rotating cylinder 6. When the first rotating cylinder 5 rotates, it will drive the second rotating cylinder 6 to rotate, thereby driving the fan 7 to run and cool the motor 1. The limiting hemisphere 103 mentioned above will have its outer wall pressed against the outer wall of the fan 7 during the operation of the fan 7, which can prevent the fan 7 from driving the second rotating cylinder 6 to slide out from the outer wall of the first rotating cylinder 5 during the operation. The above structural setting can adjust the rotation of the fan 7 according to the heat generated by the motor 1, saving the energy consumption of the motor 1.

[0032] Working principle:

[0033] When the motor 1 is in use, the motor rotor 2 will rotate when the power is just turned on, but the fan 7 will not rotate until the motor 1 has been running for a period of time and a large amount of heat is generated. The control host 101 can reduce the speed of the motor rotor 2 when the heat of the motor 1 reaches a limited temperature, and the heat is transferred from the outer wall of the motor 1 to the control disk 3, causing the mercury in the mercury injection groove 301 inside the control disk 3 to expand due to the heat, thereby pushing the piston column 4 to move toward the first rotating cylinder 5, driving the first rotating cylinder 5 to move in the same direction, and the first limiting column 502 will also move with the displacement of the first rotating cylinder 5 until it moves to In the area where the third limiting post 201 is speed-limited and rotates slowly, the third limiting post 201 will drive the first rotating cylinder 5 to rotate during rotation, and the second rotating cylinder 6 slidably connected to the outer wall of the first rotating cylinder 5 will rotate along with the first rotating cylinder 5 under the limitation of the second limiting post 501. At this time, the fan 7 will rotate accordingly, and the wind blown out from the fan 7 will move along the outer wall of the control panel 3 toward the direction of the clamping frame 105, and then blow toward the heat sink 104 along the outer wall of the clamping frame 105, so as to cool the motor 1 and reduce the temperature to the limited temperature of the control host 101, thereby restoring the speed of the motor rotor 2.

[0034] During long-term use, the blades of the fan 7 are inevitably covered with dust. As the dust accumulates, the energy consumption of the motor 1 will increase. At this time, the cover 102 of the motor 1 can be opened and the fan 7 can be removed for cleaning. Since the second rotating cylinder 6 is slidably connected to the outer wall of the first rotating cylinder 5, the fan 7 can be easily removed, and the control disk 3 is clamped on the outer wall of the clamping frame 105. The control disk 3 can be removed by hand by pulling the control disk 3 in conjunction with the deformation of the clamping frame 105 to clean the dust on the control disk 3. The installation method is also very convenient. You only need to put the control disk 3 on the motor rotor 2 and clamp it on the clamping frame 105. At this time, the S-shaped plate on the clamping frame 105 The two parts cooperate with each other and deform along their respective bending directions. The several segmented grooves 106 on the outer wall of the S-shaped plate in the clamping frame 105 will cause it to deform in the direction of its own bending in sequence during the clamping process. After the control disk 3 is clamped, the sliding groove 601 on the second rotating cylinder 6 can be aligned with the second limiting column 501 on the first rotating cylinder 5 and slid. Finally, the cover plate 102 is screwed to the motor 1. The outer wall of the limiting hemisphere 103 on the inner wall of the cover plate 102 will press against the outer wall of the fan 7, which can prevent the fan 7 from driving the second rotating cylinder 6 to slide out of the outer wall of the first rotating cylinder 5 during operation.
