[0035] ​The utility model provides a water -cooled high -efficient brushless motor, including main body motor 1 and setting in the middle part of main body motor 1 stabilizing mechanism 2, main body motor 1 includes setting in the outside of main body motor 1 motor shell 101, the one end outside fixed ear 102 of motor shell 101 is fixed with the fixed ear 102, and the rear of motor shell 101 is installed with the installation rear shell 103, the upper side of motor shell 101 is provided with water inlet joint 104, and the upper side of motor shell 101 is provided with water outlet joint 105.

[0036] Stabilizing mechanism 2 includes setting in the middle part of main body motor 1 rotating shaft 201, the outer surface annular of rotating shaft 201 is provided with rotor core 202, and the outside of rotor core 202 is provided with stator tooth portion 203, the upper end of stator tooth portion 203 is integrally fixed with stator yoke portion 204, and the bottom of stator tooth portion 203 is provided with slot 205 on both sides, and one side of stator tooth portion 203 is provided with auxiliary tooth portion 206, and the top of auxiliary tooth portion 206 is integrally fixed with auxiliary yoke portion 207, one side of stator yoke portion 204 is provided with matching boss 208, and the other side of stator yoke portion 204 is provided with matching groove 209.

[0037] The outer surface of auxiliary yoke portion 207 is fixed with thickened yoke block 210, and the connecting place of stator tooth portion 203 and stator yoke portion 204 is provided with first magnetic flux guide bridge 211 on both sides, and the connecting place of auxiliary tooth portion 206 and auxiliary yoke portion 207 is provided with second magnetic flux guide bridge 212 on both sides, and the outside of stator tooth portion 203 and auxiliary tooth portion 206 is provided with insulating wrapping sleeve 213.

[0038] Stator tooth portion 203 and stator yoke portion 204 are provided with nine groups about the outside of rotating shaft 201, and one group of auxiliary tooth portion 206 and auxiliary yoke portion 207 is arranged between every three groups of stator tooth portion 203 and stator yoke portion 204, and auxiliary tooth portion 206 and auxiliary yoke portion 207 are provided with three groups about the outside of rotating shaft 201.

[0039] Every two stator yoke portions 204 of adjacent groups are connected by embedding through matching boss 208 and matching groove 209, and the embedding connection of adjacent two stator yoke portions 204 and auxiliary yoke portion 207 is also through matching boss 208 and matching groove 209, first magnetic flux guide bridge 211 is integrally arranged between stator tooth portion 203 and stator yoke portion 204, and second magnetic flux guide bridge 212 is integrally arranged between auxiliary tooth portion 206 and auxiliary yoke portion 207.

[0040] By matching the boss 208 and the matching groove 209, the three auxiliary electrodes formed by the three groups of auxiliary teeth 206 and auxiliary yoke parts 207 can be equidistantly assembled between the stator teeth 203 and the stator yoke parts 204, so that the auxiliary teeth 206, the auxiliary yoke parts 207, the stator teeth 203 and the stator yoke parts 204 together form the stator core of the main motor 1. After the insulating wrapping sleeve 213 is sleeved on the stator teeth 203 and the auxiliary teeth 206, the wire is wound outside the corresponding insulating wrapping sleeve 213 of each stator tooth 203, so that the stator core can cooperate with the existing rotor core 202 to rotate the rotating shaft 201 after energization, thereby realizing the function of twelve-slot ten-pole on the basis of the existing nine-slot ten-pole scheme, improving the winding coefficient, and combining the auxiliary slot and the increased slot number to further reduce the torque ripple, which is conducive to reducing the radial tension after electromagnetic energization, so that the overall vibration noise is lower. At the same time, the existing nine-slot stator is modified, without the need to additionally set the winding method and independently set the multiple stator modules, without the need for integral molding processing, thereby reducing the cost of research and development and manufacturing.

[0041] The thickened yoke block 210 integrally formed with the outer surface of the auxiliary yoke part 207 increases the position thickness of each auxiliary yoke part 207, forms a protruding yoke part, and increases the magnetic area of the thickened auxiliary yoke part 207 to accommodate the magnetic flux near the auxiliary slot, thereby avoiding the problem that the added auxiliary yoke part 207 is easily saturated due to the concentration of magnetic flux. The first magnetic bridge 211 and the second magnetic bridge 212 are arranged at the connection position of the stator tooth root and the yoke part, and the magnetic flux of the tooth part is shunted to the yoke part through the magnetic bridge to reduce the main magnetic flux density of the tooth part and further reduce the problem of magnetic flux saturation. The magnetic bridge is integrally arranged with the tooth part and the yoke part, and does not increase the magnetic resistance, thereby facilitating the efficient and stable operation of the motor after the auxiliary electrode is arranged.

[0042] In order to solve the technical problem that the stator will be displaced by thermal expansion and tensile extrusion in a high-temperature and high-speed environment, these forces will be directly transmitted to the machine shell, thereby affecting the stable use of the motor, such as Figures 1-8 As shown in the figure, the following preferred technical solutions are provided:

[0043] The outer surface of the stabilizing mechanism 2 is provided with a supporting mechanism 3, which includes a supporting pad sleeve 301 arranged between the stator yoke part 204 and the inner wall of the mounting rear shell 103. The supporting pad sleeve 301 is provided with two mounting cavities 302 on the inside, and a first memory spring 303 is arranged in each of the two mounting cavities 302.

[0044] The inner side of the installation cavity 302 is fixedly provided with a fixed guide plate 304, one side of the fixed guide plate 304 is provided with a fixed seat 305, the front side of the fixed seat 305 is fixedly provided with a plug-in sliding plate 306, the plug-in sliding plate 306 is slidably connected with the fixed guide plate 304, one end of the fixed seat 305 is fixedly connected with the first memory spring 303, the other end of the first memory spring 303 is fixedly connected with the side wall of the installation cavity 302, and the thickness of the support pad sleeve 301 is greater than the thickness of the thickened yoke block 210.

[0045] The upper and lower sides of the two ends of the support pad sleeve 301 are provided with fixed ends 307, the inner side of the middle part of the fixed end 307 is provided with a plug-in sliding groove 308, the front end of the plug-in sliding groove 308 is provided with a connecting pad 309, the fixed end 307 is fixedly connected with the connecting pad 309, the plug-in sliding plate 306 is slidably connected with the plug-in sliding groove 308, the first memory spring 303 is a memory metal spring that can deform with temperature, and it is in an extended state at normal temperature and is in a contracted state when high temperature is encountered, and the specific temperature deformation can be specially made according to the use of different motors, such as being contracted when high temperature of fifty degrees is encountered.

[0046] When the motor is stably working at normal temperature, the first memory spring 303 is in an expanded state, at which time the plug-in sliding plate 306 is plugged into the plug-in sliding groove 308 in the middle of the fixed end 307, and the upper surface of the fixed end 307 is attached to the inner wall of the installed rear shell 103, and the lower surface is attached to the upper surface of the stator yoke 204, so that the stator realizes hard support between the hard fixed end 307 and the inner wall of the installed rear shell 103, thereby ensuring smooth operation when the motor is stably working. When the motor is working at high power and high speed for a long time, the temperature of the motor as a whole will continue to rise, and the radial tension received by the stator will also continue to increase. At this time, as the temperature rises, the first memory spring 303 will be recovered and compressed, thereby driving the plug-in sliding plate 306 out of the plug-in sliding groove 308 with the fixed seat 305, so that the middle interlayer of the fixed end 307 loses the support of the hard plug-in sliding groove 308. The material of the connecting pad 309 and the support pad sleeve 301 is a silicon rubber composite material with a certain elasticity, and the elastic deformation is small, such as plus or minus 0.05 millimeters, to prevent excessive deformation from affecting the stable use of the motor. At this time, the stator will be supported by the elastic connecting pad 309 and the support pad sleeve 301 with the inner wall of the installed rear shell 103. When the motor cooling is not timely or fails, due to working in a high temperature and high speed environment, the stator may be deformed by thermal expansion and tensile pressure. At this time, the small deformation of the connecting pad 309 and the support pad sleeve 301 can allow the stator to deform a certain displacement, thereby reducing the possibility of these forces being directly transmitted to the installed rear shell 103. It can directly buffer the radial magnetic tension, further reduce vibration and noise, and simplify manufacturing and maintenance, adapt to wide working conditions, to ensure efficient use of the motor. When the motor is stably working at normal temperature, the first memory spring 303 will be stretched again, pushing the plug-in sliding plate 306 back into the plug-in sliding groove 308 to realize the hard support of the plug-in sliding groove 308 and the fixed end 307.

[0047] To solve the technical problem that the water-cooled motor cannot automatically adjust the cooling power according to its own temperature, which is easy to cause excessive consumption or poor cooling effect, as shown in Figure 1 、 Figure 2 and Figures 9-11 , the following preferred technical solutions are provided:

[0048] The upper part of the main body motor 1 is provided with a temperature guide mechanism 4, which comprises a mounting groove 401 formed in the rear inner wall of the mounting rear shell 103, a second memory spring 402 mounted at the rear of the mounting groove 401, a mounting sliding plate 403 fixed at the front end of the second memory spring 402, a rotating frame 404 mounted on one end of the upper part of the mounting sliding plate 403, and the rotating frame 404 is rotatably connected with the mounting groove 401, the mounting sliding plate 403 is slidably connected with the mounting groove 401, and the second memory spring 402 is a memory metal that expands when heated.

[0049] The upper side of the rotating frame 404 is provided with a shielding sliding plate 405, the rear side of the shielding sliding plate 405 is provided with a first water inlet 406, one side of the first water inlet 406 is provided with a second water inlet 407, the output end of the first water inlet 406 is connected with a first flow-through groove 411, the output end of the second water inlet 407 is connected with a second flow-through groove 412, the first water inlet 406 and the second water inlet 407 are communicated and arranged below the front side of the water inlet connector 104, the water inlet connector 104 is connected with an external circulating refrigeration pump, and the shielding sliding plate 405 is adapted with the sliding groove of the mounting groove 401.

[0050] The front end of the mounting sliding plate 403 is fixed with a fixed top rod 408, the front side of the fixed top rod 408 is provided with a contact button 409, the contact button 409 is mounted on the lower front side of the mounting groove 401, the lower side of the contact button 409 is connected with a connecting line 410, the inner side of the water outlet connector 105 is fixed with a water distribution plate 5, the upper side of the water distribution plate 5 is provided with a one-way rotating plate 6, the first water inlet 406 is communicated with the lower water outlet of the first flow-through groove 411 and the one-way rotating plate 6, the second water inlet 407 and the second flow-through groove 412 are communicated with the rear opposite side water outlet of the one-way rotating plate 6, the first flow-through groove 411 and the second flow-through groove 412 are spirally arranged on the upper surface of the mounting rear shell 103, and they are not communicated, the contact button 409 is a high-power control key of the motor external refrigeration pump, and is connected with the external refrigeration pump control end through the connecting line 410.

[0051] When the motor is working normally, the external refrigeration pump is in a low-power state at this time, the second memory spring 402 is in a contracted state, and the blocking slide plate 405 closes the first water inlet 406 of the second flow channel 412, so that the cooling liquid of the water inlet connector 104 only passes through the second water inlet 407 through the first flow channel 411, and finally flows out from the opposite side of the one-way rotating plate 6 in the water outlet connector 105. The one-way rotating plate 6 of the one-way liquid outlet can prevent the cooling liquid from flowing back into the second flow channel 412, so that the second flow channel 412 is in an idle state, so that when the motor is working at low power, the cooling liquid can flow and dissipate heat in a small range and at low power. When the motor is working at high power, the temperature continues to rise, at which time the second flow channel 412 dissipates heat, and the low-power running cooling pump cannot meet the heat dissipation, and the temperature of the motor continues to rise. At this time, the second memory spring 402 is continuously expanded and moved forward under the influence of the temperature, so as to drive the middle part of the rotating frame 404 to rotate around the mounting groove 401 by using the installation slide plate 403, so that the rotating frame 404 pulls the blocking slide plate 405 to the left, so that the blocking slide plate 405 loses the closing of the first water inlet 406. At the same time, the fixed top rod 408 is also pulled forward by the installation slide plate 403 to press and trigger the contact button 409. At this time, the opened first water inlet 406 will pass the cooling liquid into the second flow channel 412, and finally flow out from the one-way rotating plate 6 into the water outlet connector 105, so as to flow in double channels and improve the heat dissipation area. The triggered contact button 409 can increase the power of the refrigeration pump to speed up the circulation efficiency. In this way, the automatic reaction to the temperature can realize on-demand heat dissipation, which can ensure that the temperature does not exceed at high temperature, and avoid excessive cooling at low temperature, so that the motor always works in the best temperature range, which is beneficial to energy saving and also ensures the use effect of the motor.
