DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0029] Embodiment 1: Figure 1-Figure 7 As shown, a stator assembly includes a liquid cooling assembly 1, and the liquid cooling assembly 1 includes a tooth frame 101, and a plurality of tooth mounting platforms 102 are installed on the outer side of the tooth frame 101. A coil 104 is sleeved on the tooth mounting platform 102, and the outer side of the coil 104 is fixed by a shell 4. This is a tooth yoke separation type stator, and a cooling pipe assembly is detachably installed on the tooth mounting platform 102. Through the technical solution of the present invention, the cooling pipe assembly can greatly reduce the temperature of the stator assembly, and can also reduce the temperature inside the entire motor, and the detachable cooling pipe assembly has great advantages in maintenance and installation, and is simple and efficient.

[0030] A terminal block 6 is fixedly mounted on the upper side of the tooth skeleton 101, and a terminal post 7 is rotatably mounted on the terminal block 6. Notches 9 are provided on the terminal block 6 and the terminal post 7. The wire ends on the coil 104 are stuck in the notches 9, and then the rotating cap 8 is installed on the terminal post 7. The terminal post 7 is connected to a power source, and the wire ends wound on the coil 104 are inserted into the notches 9. The terminal post 7 is rotated and the wire ends are wound around the terminal post 7. Because the terminal post 7 is connected to a power source, the coil 104 can be energized, which allows the coil 104 to be energized and also facilitates wiring.

[0031] In this embodiment, the cooling pipe assembly includes an annular pipe 103, which is sleeved between the coil 104 and the tooth mounting platform 102. The portion of the tooth mounting platform 102 where the annular pipe 103 is sleeved is thinner than other portions. Specifically, a step is formed on the tooth mounting platform 102 near the tooth frame. The annular pipe 103 is sleeved on the lower portion of the step on the tooth mounting platform 102, and the outer side of the annular pipe 103 is flush with the higher portion of the step on the tooth mounting platform 102. When the annular pipe 103 is sleeved on the tooth mounting platform 102, the step of the tooth mounting platform 102 abuts against the annular pipe 103, which plays a role of limiting. After the annular pipe 103 is sleeved, the diameter is the same as other portions, and then the coil 104 is sleeved on the outer side of the annular pipe 103, which can stably fix the coil 104, and finally the housing 4 is sleeved on the outer side of the tooth mounting platform 102.

[0032] A motor comprises the above-mentioned stator assembly, and also comprises a rotor 3, a central shaft 5 is mounted on the rotor 3, the rotor 3 is installed in the stator assembly, a wind cooling assembly 2 is mounted on the central shaft 5, the wind cooling assembly 2 comprises a fan 201, a stirring wheel 202 and a blocking plate 205, the fan 201, the stirring wheel 202 and the blocking plate 205 are fixedly mounted on the central shaft 5 from the inside to the outside, a plurality of one-way holes 206 are fixedly mounted on the blocking plate 205, the one-way holes 206 are unidirectionally ventilated, and the ventilation is ventilated from the outside to the inside of the blocking plate 205; a circular inclined Plate 1 203 and annular inclined plate 204, specifically, the bottom end of the annular inclined plate 1 203 is fixedly connected to the blocking plate 205, that is, it is connected to the central axis 5 through the blocking plate 205, and the annular inclined plate 204 is fixedly connected to the periphery of the stirring wheel 202, that is, the annular inclined plate 204 is fixedly connected to the central axis 5 through the stirring wheel 202, the purpose of which is to allow the annular inclined plate 1 203 and the annular inclined plate 204 to rotate synchronously with the central axis 5. As long as the synchronous rotation can be guaranteed, other connection methods also fall within the protection scope of this case, such as Figure 6As shown, the annular inclined plate 204 is divided into three parts. The first part is the inclined part. At the outermost side, a horizontal part is arranged on the inner side of the top end of the inclined part, and a connecting part is arranged on the inner side of the horizontal part. The connecting part is fixedly connected to the agitator wheel 202. The inclined surface arranged on the side of the annular inclined plate 1 203 is upward away from the axis, and the inclined surface of the annular inclined plate 204 is downward away from the axis. The annular inclined plate 204 is on the outer side of the annular inclined plate 1 203. A one-way hole 207 is fixedly installed on the annular inclined plate 204, and the one-way hole 207 ventilates from the inside to the outside. The diameter of the sealing plate 205 is smaller than the diameter of the outer shell 4. When the central axis 5 rotates, the fan 201 blows air into the motor, and the air enters from the one-way hole 1 206. When passing through the agitator 202, heavy particles such as dust will be thrown to the side wall of the annular inclined plate 1 203. Along with the shape of the annular inclined plate 1 203, the particles move into the motor, and finally move to the horizontal part of the annular inclined plate 204, and are blocked by this horizontal part and cannot continue to move into the motor, and then are discharged from the motor along the inclined part of the annular inclined plate 204. The centrifugal force generated by the rotation of the annular inclined plates 1 203 and 204 throws out the impurities, and the wind enters the motor from the one-way hole 1 206 and is blown out from the one-way hole 207. At the same time, the outward blowing is also directed toward the inclined part of the annular inclined plate 204 to blow air out of the motor, thereby assisting in the discharge of impurities.

[0033] Implemented two: Figure 8 As shown, the difference from the first embodiment is the liquid cooling assembly 1. In this embodiment, the cooling pipe assembly in the liquid cooling assembly 1 includes a cooling pipe 108, on which a water inlet pipe 109 and a water outlet pipe 110 are installed. A plurality of liquid cooling plates 107 are arranged on the cooling pipe 108, and a pipeline connected to the cooling pipe 108 is arranged in the liquid cooling plate 107. A circular groove 105 is arranged on the tooth frame 101, and a vertical groove 106 is arranged on the tooth mounting platform 102, which is used to cooperate with the cooling pipe 108 and the liquid cooling plate 107. The water inlet pipe 109 and the water outlet pipe 110 are connected by an external circulation pump. In the first embodiment, the cooling liquid in the liquid cooling assembly 1 does not circulate, and the inner side of the liquid cooling plate 107 is covered with pipelines that can be arranged arbitrarily. Through the technical solution of the present invention, the cooling pipe structure can be installed or removed very quickly and can be kept fixed.

[0034] Implemented three: Figure 9-11As shown, the difference from the first embodiment is the liquid cooling component 1. In this embodiment, the cooling pipe assembly in the liquid cooling component 1 includes a second cooling pipe 113, on which a second water inlet pipe 111 and a second water outlet pipe 112 are installed. The second cooling pipe 113 is annular, and a plurality of transverse cooling pipes 114 are arranged on the second cooling pipe 113. A fixing plate 122 is fixedly installed on the lower side of the transverse cooling pipe 114, and a longitudinal cooling pipe 115 is installed on the fixing plate 122. There are two channels in the transverse cooling pipe 114 and the longitudinal cooling pipe 115, and the two channels can form a loop, and finally the second water inlet pipe 111 and the second water outlet pipe 112 are connected respectively, and the longitudinal cooling pipe 115 is connected to the transverse cooling pipe 114; a hydraulic cylinder 116 is fixedly installed on the fixing plate 122, and the two channels of the longitudinal cooling pipe 115 are connected to the hydraulic cylinder 116 respectively. The front and rear ends of 116 are used to control the cylinder arm. The hydraulic cylinder 116 is driven by the longitudinal cooling pipe 115. A circulating pump and a relief valve throttle valve are arranged outside the liquid cooling component 1 to control the pressure of the hydraulic cylinder 116. A first connecting rod 118 is hinged on the cylinder arm of the hydraulic cylinder 116. A second connecting rod 119 is hinged on the first connecting rod 118. The second connecting rod 119 is hinged on a fixed shaft 121. The fixed shaft 121 is fixedly installed on a fixed plate 122. A top plate 120 is hinged at the hinge of the second connecting rod 119 and the first connecting rod 118; a plurality of return pipes 123 are installed on the lower side of the cooling pipe 113, and the return pipe 123 is connected to the cooling pipe 113. A cooling hole is arranged on the tooth skeleton 101, and the return pipe 123 is inserted into the cooling hole. The top plate 120 just supports the outer edge of the coil 104.

[0035] When in use, first install the coil 104. After the installation is completed, the entire cooling pipe assembly is inserted from the top, and the return pipe 123 enters the cooling hole on the tooth skeleton 101. The fixing plate 122 is located outside the coil 104. After being inserted to the bottom, the coolant starts to circulate and the pressure is adjusted to control the cylinder arm of the hydraulic cylinder 116 to extend. At this time, the hinge point of the first connecting rod 118 and the second connecting rod 119 will be arched, and the top plate 120 will be able to fit the outside of the coil 104, and then squeeze to tightly fix the coil 104. In this way, a slightly loose coil 104 can be designed, which will be more efficient during installation. It is then fixed by the top plate 120, which can both complete cooling and fixation. Through the technical solution of the present invention, the cooling pipe assembly can cool the inside of the tooth mounting platform 102, and the circulating liquid drives the hydraulic cylinder 116 to work. The hydraulic cylinder 116 can push the top plate 120 to clamp the coil 104, which can both cool and fix.

[0036] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
