Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a multi-winding anti-overheating motor. Background Art

[0002] A multi-winding structure motor refers to a motor that contains multiple independent windings, and each winding can be energized separately or used in combination.

[0003] Through the winding combination inside the multi-winding structure motor, the torque can be increased or decreased according to the need. This multi-winding structure motor is widely used in various industrial and manufacturing fields and has high flexibility and adaptability.

[0004] When the multi-winding structure motor is working, it will start the required winding structure through the PLC in the internal controller for power-on use. The energized winding itself will generate a lot of heat, while the other non-energized winding structures are not powered on.

[0005] Since each winding structure is generally arranged horizontally and sleeved on the rotor, and the cooling fan of the multi-winding structure motor is generally only installed on the end cover singly and realizes overall cooling of all the winding structures inside the motor housing, this will cause the heat of a certain working winding structure to not be effectively dissipated and cause overheating, which will reduce the service life of the multi-winding structure motor.

[0006] The above problems are widespread and urgently need to be improved. Content of the Utility Model

[0007] The purpose of the utility model is to solve the above-mentioned drawbacks in the prior art and propose a multi-winding anti-overheating motor.

[0008] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0009] Design a multi-winding anti-overheating motor, including a motor housing. The outer wall of the motor housing is provided with heat sinks, and the heat sinks are provided with heat discharge ports. The motor housing is provided with an end cover, and the end cover is provided with a controller. The motor housing is provided with a first air inlet cover, a second air inlet cover, a third air inlet cover, and a fourth air inlet cover. The motor housing is provided with a bottom mounting seat, and the bottom mounting seat is provided with a mounting plate and an air passage. The motor housing is provided with a first discharge cover, a second discharge cover, a third discharge cover, and a fourth discharge cover. The first discharge cover is provided with a first fan, the second discharge cover is provided with a second fan, the third discharge cover is provided with a third fan, and the fourth discharge cover is provided with a fourth fan. The bottom mounting seat is provided with air holes and heat conduction grooves.

[0010] Further, there are fifteen heat sinks arranged in a circular pattern, and the heat sinks are embedded in the outer wall of the motor housing. The heat exhaust port is a long strip-shaped opening structure.

[0011] Further, the side cross-section of the bottom mounting base is trapezoidal, and the air passage runs longitudinally through the bottom mounting base.

[0012] Further, the side cross-section of the heat conduction groove is arc-shaped, and the heat conduction groove runs longitudinally through the bottom mounting base and communicates with the air vent holes.

[0013] Further, the controller is installed on the right end face of the end cover.

[0014] Further, the first exhaust cover is arranged at the top of the motor housing, the second exhaust cover is arranged at the top of the motor housing, the third exhaust cover is arranged at the top of the motor housing, and the fourth exhaust cover is arranged at the top of the motor housing.

[0015] Further, dust-proof nets are provided at the tops of the first exhaust cover, the second exhaust cover, the third exhaust cover, and the fourth exhaust cover.

[0016] A multi-winding anti-overheating motor proposed by the present utility model has the following beneficial effects:

[0017] 1. By arranging a controller on the end cover, four groups of electric control needle-type air extraction and heat dissipation structures on the motor housing, a through-type air passage and heat conduction grooves on the bottom mounting base, and providing targeted air vent holes on the bottom mounting base, the present utility model can perform targeted air extraction and heat dissipation for a certain working winding structure in the motor housing, avoiding the situation where the heat of a certain working winding structure cannot be effectively dissipated and overheats due to only relying on a single fan on the end cover to conduct overall heat dissipation inside the motor housing, thereby improving the service life of the multi-winding structure motor.

[0018] 2. By arranging a heat sink structure with a heat exhaust port on the outer wall surface of the motor housing, the present utility model can further improve the effective auxiliary heat dissipation effect for the overall heat of the motor housing. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Referring to Figures 1-6 , a multi-winding anti-overheating motor includes a motor housing 1. A heat sink 5 is provided on the outer wall of the motor housing 1, and a heat exhaust port 51 is provided on the heat sink 5. An end cover 2 is provided on the motor housing 1, and a controller 21 is provided on the end cover 2. The motor housing 1 is provided with a first air inlet cover 11, a second air inlet cover 12, a third air inlet cover 13, and a fourth air inlet cover 14. A bottom mounting seat 3 is provided on the motor housing 1, and a mounting plate 4 and an air passage 30 are provided on the bottom mounting seat 3. The motor housing 1 is provided with a first exhaust cover 61, a second exhaust cover 62, a third exhaust cover 63, and a fourth exhaust cover 64. A first fan 81 is provided in the first exhaust cover 61, a second fan 82 is provided in the second exhaust cover 62, a third fan 83 is provided in the third exhaust cover 63, and a fourth fan 84 is provided in the fourth exhaust cover 64. Air holes 31 and heat conduction grooves 32 are formed on the bottom mounting seat 3. The motor housing 1 is a commonly used motor housing with a multi-winding structure, and four groups of multi-winding structures are arranged horizontally inside it. It is drawn in the figure and is prior art.

[0028] When performing air extraction for heat dissipation, the first air inlet cover 11, the second air inlet cover 12, the third air inlet cover 13, and the fourth air inlet cover 14 will respectively draw external cold air into the inner cavity of the motor housing 1. The cold air will exchange heat with the heat to form a hot air flow, and the hot air flow will be drawn upward and discharged to achieve a rapid air extraction heat dissipation effect.

[0029] The inner cavities of the first air inlet cover 11, the second air inlet cover 12, the third air inlet cover 13, and the fourth air inlet cover 14 are respectively communicated with the inner cavity of the motor housing 1 to achieve the air inlet effect. Moreover, filters are preset on the first air inlet cover 11, the second air inlet cover 12, the third air inlet cover 13, and the fourth air inlet cover 14 to prevent dust from entering the motor housing 1.

[0030] Specifically, there are fifteen heat sinks 5 arranged in a circular pattern. The heat sinks 5 are embedded in the outer wall of the motor housing 1. The heat exhaust port 51 is a long strip-shaped opening structure. The heat sinks 5 are made of red copper, which has excellent thermal conductivity. It can quickly conduct the heat transferred from the metal motor housing 1 and then quickly dissipate it through the heat exhaust port 51.

[0031] Furthermore, the side cross-section of the bottom mounting seat 3 is a trapezoidal structure, and the trapezoidal bottom mounting seat 3 has excellent supporting stability.

[0032] The air passage 30 longitudinally penetrates the bottom mounting seat 3. Part of the heat will also be transferred to the air passage 30 through the air holes 31 and then quickly dissipate through the penetrated air passage 30 to prevent heat accumulation.

[0033] Still further, the side cross-section of the heat conduction groove 32 is an arc-shaped structure. The heat conduction groove 32 longitudinally penetrates the bottom mounting seat 3 and is communicated with the air holes 31. Part of the heat is conducted through the outer shell of the motor housing 1 to the heat sinks 5 below and accumulates, and is dissipated through the penetrated heat conduction groove 32 to prevent heat accumulation.

[0034] More specifically, the controller 21 is installed on the right end face of the end cover 2. A PLC is preset in the controller 21. When one group, or two, or all of the four winding structures in the motor housing 1 are energized and start working, a signal will be given to the PLC, and the PLC will start the corresponding fan for targeted air extraction and heat dissipation.

[0035] Generally speaking, the first exhaust cover 61 is arranged at the top of the motor housing 1, the second exhaust cover 62 is arranged at the top of the motor housing 1, the third exhaust cover 63 is arranged at the top of the motor housing 1, and the fourth exhaust cover 64 is arranged at the top of the motor housing 1. The inner cavities of the first exhaust cover 61, the second exhaust cover 62, the third exhaust cover 63, and the fourth exhaust cover 64 are respectively communicated with the inner cavity of the motor housing 1 to achieve the rapid upward discharge of the hot air flow.

[0036] Finally, dust-proof nets 7 are provided at the tops of the first exhaust cover 61, the second exhaust cover 62, the third exhaust cover 63, and the fourth exhaust cover 64. When the motor is in use, the dust-proof nets 7 can prevent dust from entering from above.

[0037] Working mode: When the motor is powered on and in use, there are four groups of winding structures arranged horizontally inside the motor housing 1. Taking the first group of winding structures near the motor shaft on the left side of the motor housing 1 as an example, if this group of winding structures needs to be powered on and used at this time, the PLC inside the controller 21 will receive the signal given by the first group of winding structures. At this time, the PLC inside the controller 21 will control the start of the first fan 81 in the first row of covers 61. The first fan 81 will form a suction force from bottom to top, which can extract the heat generated by the currently working first group of winding structures in a targeted manner. Then the heat will be quickly discharged upward through the first row of covers 61. At the same time, during the targeted air extraction and heat dissipation, part of the heat will be discharged through the air passage 30, the air holes 31, and the heat conduction grooves 32, which can perform targeted air extraction and heat dissipation for a certain working winding structure in the motor housing 1, avoiding the situation that the heat of a certain working winding structure cannot be effectively dissipated and overheated due to only relying on a single fan on the end cover 2 to dissipate the heat inside the motor housing 1 as a whole, thereby improving the service life of the multi-winding structure motor.

[0038] In addition, part of the heat will be transferred to each heat sink 5 through the metal motor housing 1, and then the heat will be dissipated and discharged through the heat discharge port 51, which can further improve the effective auxiliary heat dissipation effect for the overall motor housing 1.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
