Description

Technical Field

[0001] This invention relates to the field of synchronous motor technology, and in particular to a low-voltage, high-power, high-efficiency permanent magnet synchronous motor. Background Technology

[0002] A permanent magnet synchronous motor is a type of synchronous motor that uses permanent magnets to establish an excitation magnetic field. It features high efficiency, high power density, and excellent speed regulation performance, and is widely used in new energy vehicles, industrial automation, home appliances, aerospace and other fields.

[0003] Electric motors generate heat during operation. Therefore, a through-hole is usually made at the end of the motor, and a filter plate is installed at the through-hole to dissipate heat and prevent debris from entering the motor. The filter screen is usually installed at the edge of the through-hole. If the motor is used in an industrial workshop or placed in an industrial environment, it may be exposed to situations such as workpieces falling or forklift collisions. The strength of the filter plate frame is usually insufficient to withstand such impacts. Therefore, multiple baffles are usually set at one end of the filter plate as the "first line of defense" to protect the filter plate from damage. However, even with the addition of baffles for protection, dust or oil will accumulate on the surface. When dust and oil mix together, they will condense on the surface of the baffles. If they are not cleaned in time, it will affect the heat dissipation efficiency. Furthermore, excessive dust accumulation also poses a risk of entering the motor and affecting its service life. Summary of the Invention

[0009] In one embodiment, a rack is fixedly installed on the inner wall of the side of the cross plate that is not on the outside, and the end of the rotating rod moves through the inner wall of the movable frame and is fixedly sleeved with a gear on the outside, and the rack meshes with the gear for transmission.

[0010] In one embodiment, the movable frame has a groove on one side of the inclined groove, a fixed cylinder is fixedly installed on the inner wall of the groove, a movable rod is movably installed inside the fixed cylinder, and a push plate is fixedly installed at the end of the movable rod away from the fixed cylinder.

[0011] In one embodiment, a return spring is axially symmetrically fixed on both sides of the side where the push plate is connected to the movable rod, and the end of the return spring away from the push plate is fixedly connected to the inner wall of the groove.

[0012] In one embodiment, the movable rod has a vertical groove, and a movable block is movably disposed in the vertical groove. The bottom of the movable block is connected to the inner wall of the vertical groove by a positioning spring.

[0013] In one embodiment, a vertical plate is fixedly installed on one side of the movable frame, and a horizontal bar is movably installed through the center of the vertical plate. A positioning block is fixedly installed at one end of the horizontal bar, and a limiting groove is opened at one end of the positioning block. A notch is opened on one side of the movable block, and the notch movably abuts against the limiting groove.

[0014] In one embodiment, the end of the crossbar furthest from the positioning block is longer than the width of the movable frame, and a ring is fixedly sleeved on the outer side of the crossbar. The ring is fixedly connected to the vertical plate by a locking spring.

[0024] The following is combined Figures 1-9 The present invention describes a low-voltage, high-power, high-efficiency permanent magnet synchronous motor.

[0025] like Figures 1-7 As shown, in one embodiment, the low-voltage, high-power, high-efficiency permanent magnet synchronous motor includes a housing 1 and an end cover 3 fixedly installed at one end of the housing 1, and further includes: The rotating shaft 2 is rotatably mounted on the end of the housing 1 away from the end cover 3; Through hole 31 is provided on end cap 3; The filter plate 4 is detachably installed in the through hole 31, and has multiple filter holes 41. The horizontal plates 5 are installed in a linear array from top to bottom in the through holes 31. Multiple plates are set and located on one side of the filter plate 4. There are equal intervals between adjacent horizontal plates 5. The lead screw 6 is rotatably installed in the through hole 31, located on one side of the horizontal plate 5, and the number of both is the same; The movable frame 7 is movably installed on the outside of the lead screw 6. A groove 71 is provided on one side. The part with the groove 71 slides and fits against the surface of the horizontal plate 5. A slot 72 is provided on the surface of the groove 71. Movable plate 8 is movably installed inside slot 72; The shaking component 9 is located inside the movable frame 7 and is used to drive the movable plate 8 to shake.

[0026] Specifically, one end of the rotating shaft 2 is connected to other mechanical equipment to provide it with a power source. During motor operation, heat is generated, which is discharged through the filter plate 4 and filter holes 41 installed in the through hole 31. This effectively controls the heat inside the motor, ensuring its working efficiency. Secondly, the presence of the filter plate 4 also prevents large particles of impurities from entering the motor and affecting its normal operation. The end cover 3, located on the outer side of the filter plate 4, also has multiple horizontal plates 5 installed. These horizontal plates 5 are spaced apart to ensure adequate heat dissipation for the motor. Furthermore, the horizontal plates 5 provide some protection for the filter plate 4. If a workpiece falls onto the end cover 3, the horizontal plates 5 will collide with the workpiece, preventing direct collision between the filter plate 4 and the workpiece, thus avoiding damage to the filter plate 4 and affecting the motor's heat dissipation and dust removal effect. The horizontal plates 5 are horizontally installed in the through hole 31. During motor use, some dust will accumulate on the surface of the horizontal plates 5. If the motor... If there is oil in the working environment, some of the oil will mix with dust and accumulate. Over time, it will solidify and become difficult to remove. Therefore, the upper surface of the horizontal plate 5 needs to be cleaned regularly. If manual cleaning is used, it will greatly increase the labor intensity of workers. At this time, the motor of the lead screw 6 can be started. The lead screw 6 rotates and drives the moving frame 7 to move laterally from one end of the horizontal plate 5 to the other end. The part of the moving frame 7 with the inclined groove 71 is in contact with the surface of the horizontal plate 5, which can remove the mixture of dust and oil on the surface of the horizontal plate 5. The mixture will accumulate on the surface of the inclined groove 71 of the moving frame 7 and the movable plate 8. Some of the mixture will stick to the movable plate 8 and is not easy to detach from the movable plate 8. Therefore, during the movement of the moving frame 7, the shaking component 9 drives the movable plate 8 to shake slightly in the groove 72 to prevent the mixture from sticking to the surface of the movable plate 8 and facilitate subsequent detachment. The housing 1 provides support for the rotating shaft 2.

[0027] See Figure 5 and Figure 7 As shown, in this embodiment, the shaking component 9 includes a connecting plate 91. One end of the connecting plate 91 is fixedly connected to the inner wall of the movable plate 8. The bottom of the connecting plate 91 is connected to the inner wall of the movable frame 7 by a plurality of shaking springs 92. The four sides of the movable plate 8 that abut against the slot 72 are made of an elastic material.

[0028] Specifically, the portion of the movable frame 7 with the inclined groove 71 slides along the surface of the horizontal plate 5 to scoop up the mixture on the surface. After the mixture is scooped up, it will accumulate on the surface of the movable plate 8. Therefore, during the movement, the connecting plate 91 is moved laterally back and forth. The lateral movement of the connecting plate 91 will cause the shaking component 9 to swing, thereby causing the connecting plate 91 to shake. The amplitude of the movement of the connecting plate 91 should not be too large, just a slight shake. The shaking of the connecting plate 91 will cause the movable plate 8 to shake within the groove 72. The contact point between the movable plate 8 and the inner wall of the groove 72 is made of an elastic material, which allows the movable plate 8 to slightly shift within the groove 72 due to the shaking. In this step, the shaking of the movable plate 8 can effectively prevent the mixture from sticking to the surface of the movable plate 8 and affecting subsequent cleaning.

[0029] See Figures 4-5 and Figure 7 As shown, in this embodiment, a vertical rod 93 is rotatably installed inside the movable frame 7 at one end of the connecting plate 91, and a cam 94 is fixedly sleeved on the outside of the vertical rod 93, with the outside of the cam 94 movably abutting against the side wall of the connecting plate 91.

[0030] Specifically, rotating the vertical rod 93 causes the cam 94 to rotate, which in turn causes the connecting plate 91 to swing slightly. With the help of the vibration spring 92, the movable plate 8 will vibrate slightly within the slot 72, thus preventing the mixture on its surface from sticking together and affecting subsequent detachment.

[0031] See Figures 5-7 As shown, in this embodiment, a rotating rod 10 is rotatably provided at the end of the movable frame 7 away from the vertical rod 93. One end of the rotating rod 10 moves through the inner wall of the movable frame 7, and the end of the rotating rod 10 is located on one side of the side wall of the horizontal plate 5. The rotating rod 10 and the vertical rod 93 are connected by a belt 11.

[0032] Specifically, when the movable frame 7 slides along the surface of the horizontal plate 5 under the action of the lead screw 6, it uses the inclined groove 71 to scoop up the mixture on the surface of the horizontal plate 5. During the movement, the rotating rod 10 also moves together. The rotation of the rotating rod 10 will drive the vertical rod 93 to rotate synchronously through the action of the belt 11. The rotation of the vertical rod 93 will drive the cam 94 to rotate, thereby realizing the shaking of the connecting plate 91 and the movable plate 8, which can prevent the mixture from sticking.

[0033] See Figure 6 As shown, in this embodiment, a rack 12 is fixedly installed on the inner wall of the side of the horizontal plate 5 that is not on the outside. The end of the rotating rod 10 moves through the inner wall of the movable frame 7 and is fixedly sleeved with a gear 13 on the outside. The rack 12 and the gear 13 mesh and drive each other.

[0034] Specifically, during the movement of the movable frame 7, the rotating rod 10 and the gear 13 move synchronously together. During the movement of the gear 13, it will mesh with the rack 12 installed on the inner side wall of the horizontal plate 5. The gear 13 will rotate, driving the rotating rod 10 to rotate synchronously. With the help of the belt 11, the vertical rod 93 will rotate, which can realize the shaking of the movable plate 8. In this step, the cooperation of the gear 13 and the rack 12 can realize that the movable plate 8 can shake while the movable frame 7 is shoveling the mixture, avoiding the mixture from sticking together. The operation is highly coordinated and convenient and quick.

[0035] See Figures 4-7 As shown, in this embodiment, the movable frame 7 has a groove 73 on one side of the inclined groove 71. A fixed cylinder 14 is fixedly installed on the inner wall of the groove 73. A movable rod 15 is movably installed inside the fixed cylinder 14. A push plate 16 is fixedly installed at the end of the movable rod 15 away from the fixed cylinder 14. The push plate 16 is inclined and slides against the surface of the inclined groove 71.

[0036] Specifically, the movable frame 7 is provided with a push plate 16 on one side of the inclined groove 71. The push plate 16 is inclined and parallel to the surface of the inclined groove 71. During the movement of the movable frame 7, the push plate 16 remains on one side of the inclined groove 71. The movable rod 15 is mostly located inside the fixed cylinder 14. When the movable frame 7 moves along one end of the horizontal plate 5 to the other end, the inclined groove 71 part of the movable frame 7 scoops up all the mixture on the surface of the horizontal plate 5. After being shaken by the movable plate 8, the mixture does not stick to the movable plate 8. At this time, the movable rod 15 is pulled outward of the fixed cylinder 14. The movable rod 15 moves laterally relative to the groove 73 and drives the push plate 16 to slide along the surface of the inclined groove 71. The push plate 16 can push all the mixture on the surface of the inclined groove 71 and the movable plate 8 to the end of the end cover 3 away from the filter plate 4. A dust collection frame can be set at the position of the end cover 3 below the through hole 31. The mixture impurities are pushed by the push plate 16 and fall into the dust collection frame for subsequent processing.

[0037] See Figure 7 As shown, in this embodiment, a return spring 17 is axially symmetrically fixed on both sides of the connection between the push plate 16 and the movable rod 15, and the end of the return spring 17 away from the push plate 16 is fixedly connected to the inner wall of the groove 73.

[0038] Specifically, during the movement of the movable frame 7, the push plate 16 is located at one end of the inclined groove 71 near the groove 73, and the return spring 17 is in a compressed state. When the movable frame 7 reaches the other end of the horizontal plate 5, the compression state of the return spring 17 is released. Under the action of the return spring 17, the push plate 16 will slide along the inclined groove 71 and the movable plate 8 to push away the mixture on the surface. The movable rod 15 moves outward along the fixed cylinder 14 to ensure that the push plate 16 will not deviate during the movement. Both the movable rod 15 and the fixed cylinder 14 need to be made of materials with low coefficient of friction to reduce the friction force during the movement of the movable rod 15.

[0039] See Figure 8 and Figure 9 As shown, in this embodiment, the movable rod 15 has a vertical groove 151, and a movable block 18 is movably disposed in the vertical groove 151. The bottom of the movable block 18 is connected to the inner wall of the vertical groove 151 by a positioning spring 19.

[0040] Specifically, when the return spring 17 is in the compressed state, part of the movable block 18 is located outside the vertical groove 151, and a limiting force is applied to one end of the movable block 18. The positioning spring 19 is in the normal extension and contraction state. At this time, the push plate 16 is located at one end of the inclined groove 71. When the moving frame 7 reaches the other end of the horizontal plate 5, the force applied to the movable block 18 is released. Under the action of the return spring 17, the push plate 16 will slide along the surface of the inclined groove 71 to remove the mixture accumulated on the surface.

[0041] See Figure 8 and Figure 9 As shown, in this embodiment, a vertical plate 20 is fixedly installed on one side of the movable frame 7, and a horizontal bar 21 is movably installed through the center of the vertical plate 20. A positioning block 22 is fixedly installed at one end of the horizontal bar 21, and a limiting groove 221 is opened at one end of the positioning block 22. A notch 181 is opened on one side of the movable block 18, and the notch 181 movably abuts against the limiting groove 221.

[0042] Specifically, when the push plate 16 is located at one end of the inclined groove 71, the end of the positioning block 22 without the limiting groove 221 abuts against the end of the movable block 18 without the notch 181, and the return spring 17 is in a compressed state. When the moving frame 7 reaches the other end of the horizontal plate 5, the horizontal bar 21 moves towards the fixed cylinder 14. The horizontal bar 21 moves laterally relative to the vertical plate 20, which drives the positioning block 22 to move laterally. The positioning block 22 no longer abuts against the movable block 18. Under the action of the return spring 17, it drives the movable rod 15 and the push plate 16 to move. The push plate 16 can push away the mixture accumulated on the surface of the inclined groove 71 and the movable plate 8. After cleaning, the moving frame 7 moves in the opposite direction along the horizontal plate 5 under the drive of the screw 6. At this time, The reverse movement of the horizontal bar 21 returns the positioning block 22 to its initial position. Then, the push plate 16 is pushed to move the movable rod 15 into the fixed cylinder 14. During the movement, the movable rod 15 causes the notch 181 of the movable block 18 to abut against the limiting groove 221 of the positioning block 22. The movable block 18 moves downward along the vertical groove 151, thereby compressing the positioning spring 19. When the movable block 18 passes under the positioning block 22 and moves to the other side of the positioning block 22, it will be driven to move upward under the action of the positioning spring 19. The end of the movable block 18 without the notch 181 abuts against the end of the positioning block 22 without the limiting groove 221. The movable block 18 remains fixed, which facilitates the subsequent cleaning of the horizontal plate 5.

[0043] See Figure 8As shown, in this embodiment, the end of the crossbar 21 away from the positioning block 22 is longer than the width of the movable frame 7. A ring 23 is fixedly sleeved on the outside of the crossbar 21, and the ring 23 is fixedly connected to the vertical plate 20 by a locking spring 24.

[0044] Specifically, the moving frame 7 slides along the surface of the horizontal plate 5. When it is about to reach the other end of the horizontal plate 5, the end of the horizontal bar 21 away from the positioning block 22 first abuts against the inner wall on the other side of the through hole 31. The moving frame 7 continues to move in the same direction. Under the action of the inner wall, the horizontal bar 21 will move in the opposite direction, driving the ring 23 to move and compressing the locking spring 24. The positioning block 22 will move laterally and no longer abut against the movable block 18. Under the action of the reset spring 17, the push plate 16 will move laterally to push the mixture. Then the moving frame 7 moves in the opposite direction, and the horizontal bar 21 no longer abuts against the inner wall of the through hole 31. Under the action of the locking spring 24 returning to its original state, the ring 23, the horizontal bar 21 and the positioning block 22 will move in the opposite direction to the initial position. Then the push plate 16 and the movable block 18 will be pushed in the opposite direction to the initial position, which is convenient for subsequent cleaning of the surface of the horizontal plate 5.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
