[0057] The following Figure 1 , Figure 2 and Figure 3 will be used to describe an application of the rotary liquid supply device and control method applied to the electric motor of the present application.

[0058] Refer to Figure 1, the first aspect of the present application provides a rotary liquid supply device applied to a motor. The motor 100 generally includes a first rotor 101 and an upper frame 102, and there is a first gap 103 between the first rotor 101 and the upper frame 102. The rotary liquid supply device 200 generally includes a liquid supply tank 201, a liquid receiving tank 202, a sliding power mechanism 203, and a control mechanism 204. Among them, the sliding power mechanism 203 is located in the first gap 103 and is installed on the upper frame 102. The liquid supply tank 201 is connected to the sliding power mechanism 203. The control mechanism 204 is installed on the liquid supply tank 201 and is communicatively connected to the sliding power mechanism 203 to drive the liquid supply tank 201 to rotate. The liquid receiving tank 202 is located in the first gap 103, is installed on the first rotor 101, and is separably connected to the liquid supply tank 201 so that the liquid supply tank 201 can deliver a liquid cooling medium to the liquid receiving tank 202 to cool down the first rotor 101.

[0059] The sliding power mechanism 203 of the rotary liquid supply device applied to the motor of the present invention is arranged in the first gap 103, is installed on the upper frame 102, and the sliding power mechanism 203 is controlled by the control mechanism 204 to drive the liquid supply tank 201 to rotate. Then, the control mechanism 204 controls the connection between the liquid supply tank 201 and the liquid receiving tank 202, so that the liquid receiving tank 202 can be replenished with the liquid cooling medium without stopping the machine, thus not affecting the operation of the rotor and improving the working efficiency.

[0060] In this embodiment, the motor 100 is an existing motor, and both the first rotor 101 and the upper frame 102 are existing. The motor 100 further includes a controller for controlling the operation of the motor 100. The liquid supply tank 201 is a rectangular body or an annular body, and the liquid receiving tank 202 is a rectangular body or an annular body, as long as their shapes are the same. Both the liquid supply tank 201 and the liquid receiving tank 202 are made of stainless steel to avoid rusting. The liquid receiving tank 202 and the first rotor 101 are connected by welding or sealed screws, depending on the requirements.

[0061] Refer to Figure 1 , in a preferred embodiment of the rotary liquid supply device applied to the motor described above, the sliding power mechanism 203 generally includes a sliding connector 205 and a first motor 206. Among them, the sliding connector 205 is installed on the upper frame 102, the first motor 206 is installed inside the sliding connector 205 and is communicatively connected to the control mechanism 204, and the first motor 206 is also connected to the liquid supply tank 201. By installing the first motor 206 inside the sliding connector 205 and controlling the operation of the first motor 206 through the control mechanism 204, the rotation of the liquid supply tank 201 is realized.

[0062] Refer to Figure 1, in the preferred embodiment of the rotary liquid supply device applied to the motor as described above, the sliding connector 205 generally includes a first fixing member 207 and a second fixing member 208 with the same structure. Both the first fixing member 207 and the second fixing member 208 are fixedly connected to the upper frame 102 and are arranged oppositely. An open cavity 209 is formed between the first fixing member 207 and the second fixing member 208 for installing the first motor 206. By fixing the first fixing member 207 and the second fixing member 208 to the upper frame 102, it is convenient to install the first motor 206 and the structure is simple.

[0063] See Figure 3 , in this embodiment, the first fixing member 207 includes a first ring 223 and a first flange 224. The upper edge of the first ring 223 is welded or screwed to the upper frame 102, and the first flange 224 is pressed against the lower edge of the first ring 223. The second fixing member 208 includes a second ring 225 and a second flange 226. The upper edge of the second ring 225 is welded or screwed to the upper frame 102, and the second flange 226 is pressed against the lower edge of the second ring 225. An open cavity 209 is formed between the first fixing member 207 and the second fixing member 208 for installing the first motor 206. Among them, both the first fixing member 207 and the second fixing member 208 are made of stainless steel.

[0064] Refer to again Figure 1 , in the preferred embodiment of the rotary liquid supply device applied to the motor as described above, the first motor 206 generally includes a stator 210, a second rotor 211 and a bearing 213. Among them, the bearing 213 is located in the open cavity 209 and is sleeved on the outside of the first fixing member 207. The second rotor 211 is located in the open cavity 209 and is sleeved on the outside of the bearing 213. The stator 210 is located in the open cavity 209 and is installed on the inner side of the second fixing member 208. There is a second gap 213 between the stator 210 and the second rotor 211. The stator 210 drives the second rotor 211 to rotate around the bearing 213, thereby driving the liquid supply tank 201 to rotate together, and the rotation speed is the same as that of the first rotor 101, so that the liquid supply tank 201 and the liquid receiving tank 202 rotate synchronously, which is beneficial to their connection.

[0065] Specifically, the stator 210, the second rotor 211 and the bearing 213 are all existing ones. The bearing 213 is sleeved on the outside of the first ring 223 and is limited by the first flange 224. The second rotor 211 is sleeved on the outside of the bearing 213 and is welded to the outer ring of the bearing 213. The stator 210 is located inside the second ring 225 and abuts against the second flange 226 to limit it, preventing the stator 210 from falling off.

[0066] In this embodiment, direct current is conducted between the stator 210 and the second rotor 211.

[0067] Continue to refer toFigure 1 , in the preferred embodiment of the rotary liquid supply device applied to the motor, the liquid supply tank 201 and the second rotor 211 are connected by a suspension bracket 214.

[0068] In this embodiment, the suspension bracket 214 is composed of two connecting rods. One ends of the two connecting rods are welded to the bottom surface of the second rotor 211, and the other ends of the two connecting rods are welded to the top surface of the liquid supply tank 201 to improve rigidity and prevent damage when the liquid supply tank 201 rotates.

[0069] Refer to Figure 2 , in the above preferred embodiment, the liquid receiving tank 202 and the liquid supply tank 201 are separably connected by a separation connection assembly 215. Specifically, the separation connection assembly 215 generally includes a telescopic tube mechanism 216 and a sealed socket 217. Among them, the telescopic tube mechanism 216 is installed on the liquid supply tank 201 and communicates with the liquid supply tank 201, and the sealed socket 217 is opened on the liquid receiving tank 202 for connection with the telescopic tube mechanism 216. By installing the telescopic tube mechanism 216 on the liquid supply tank 201 and opening the sealed socket 217 on the liquid receiving tank 202, the telescopic tube mechanism 216 and the sealed socket 217 are inserted to connect the liquid supply tank 201 and the liquid receiving tank 202, so that the liquid (liquid cooling medium) inside the liquid supply tank 201 enters the liquid receiving tank 202 to continuously cool the first rotor 101. It will not stop due to the high temperature of the first rotor 101, thereby improving work efficiency. Among them, the liquid cooling medium is pure water or liquid fluorocarbon (such as freon liquid) or transformer oil.

[0070] Refer to again Figure 2, in the preferred embodiment of the rotary liquid supply device applied to the motor as described above, the telescopic tube mechanism 216 includes a telescopic tube 218, a small motor 219, a lead screw 222, a nut 228, a connecting piece 229 and a solenoid valve 220. Among them, one end of the telescopic tube 218 is connected to the liquid supply tank 201, the solenoid valve 220 is installed on the telescopic tube 218 and is communicatively connected to the control mechanism 204, the small motor 219 is installed on the liquid supply tank 210 and is communicatively connected to the control mechanism 204, and one end of the lead screw 222 is connected to the power output end of the small motor 219. The nut 228 is installed on the lead screw 222 for moving up and down on the lead screw 222. The connecting piece 229 is respectively connected to the nut 228 and the lower part of the telescopic tube 218 to drive the telescopic tube 218 to extend, so that the other end of the telescopic tube 218 is inserted into the sealing insertion port 217. The telescopic tube 218 is driven by the small motor 219 to extend and be inserted into the sealing insertion port 217, and the solenoid valve 220 is opened, and the liquid supply tank 201 and the liquid receiving tank 202 are communicated. When it is not necessary to insert the telescopic tube 218 into the sealing insertion port 217, the small motor 219 drives the telescopic tube 218 to retract, and the solenoid valve 220 is closed, so that the telescopic tube 218 and the sealing insertion port 217 are separated, and the liquid supply tank 201 and the liquid receiving tank 202 are separated.

[0071] Continue to refer to Figure 1 , in the preferred embodiment of the rotary liquid supply device applied to the motor as described above, the control mechanism 204 generally includes a controller 221 and a camera 212. Among them, the controller 221 and the camera 212 are both installed on the liquid supply tank 201, and the controller 221 and the camera 212 are communicatively connected.

[0072] Specifically, the controller 221 is an existing controller. The controller 221 is installed on the liquid supply tank 201 by screws and stores a control program. The camera 212 is also an existing camera. The camera 212 and the controller 221 are communicatively connected through a connecting wire. The camera 212 continuously captures whether the telescopic tube 218 and the sealing insertion port 217 are perpendicular. When their rotation speeds are constant and perpendicular, the small motor 219 drives the telescopic tube 218 to extend and be inserted into the sealing insertion port 217, and then the liquid supply tank 201 and the liquid receiving tank 202 are communicated to supply the liquid cooling medium.

[0073] Continue to refer to Figure 1, in the preferred embodiment of the rotary liquid supply device applied to the motor as described above, the rotary liquid supply device 200 further includes a rotational speed measuring device 227 for reading the rotational speed of the first rotor 101. The rotational speed measuring device 227 is communicatively connected to the controller 221 so that the controller 221 can control the rotational speed of the liquid supply tank 201 to be the same as the rotational speed of the first rotor 101. Among them, the rotational speed measuring device 227 is an existing rotational speed measuring device, and it is communicatively connected to the controller 221 through a connecting wire so that the controller 221 can control the rotational speed of the first motor 206 to be the same as the rotational speed of the first rotor 101, or adjust the rotational speed of the first motor 206 according to the rotational speed of the first rotor 101.

[0074] Refer to Figure 4 , in a second aspect, the present invention provides a control method for a rotary liquid supply device applied to a motor. The control method includes the following steps:

[0075] Step S011: The rotational speed measuring device 227 obtains the rotational speed value of the first rotor 101;

[0076] Step S012: The controller 221 controls the rotational speed value of the second rotor 211 to be the same as the rotational speed value of the first rotor 101 according to the rotational speed value of the first rotor 101;

[0077] Step S013: The camera 212 obtains the video of the telescopic tube 218 and the sealing socket 217;

[0078] Step S014: The controller 221 determines whether the telescopic tube 218 and the sealing socket 217 are perpendicular according to the video;

[0079] Step S015: When the telescopic tube 218 and the sealing socket 217 are perpendicular, the controller 221 controls the small motor 219 to drive the telescopic tube 218 to insert into the sealing socket 217 so that the liquid supply tank 201 and the liquid receiving tank 202 are communicated;

[0080] Step S016: When the telescopic tube 218 and the sealing socket 217 are not perpendicular, the controller 221 controls the second rotor 211 to increase or decrease the rotational speed until the telescopic tube 218 and the sealing socket 217 are perpendicular, and then the controller 221 controls the rotational speed value of the second rotor 211 to be the same as the rotational speed value of the first rotor 101.

[0081] Control method for a rotating liquid supply device applied to an electric motor. By obtaining the rotation speed value of the first rotor 101 and controlling the rotation speed value of the second rotor 211 to be the same as that of the first rotor 101 according to the rotation speed value of the first rotor 101, obtaining videos of the telescopic tube 218 and the sealing socket 217, and judging whether the telescopic tube 218 and the sealing socket 217 in the videos are perpendicular. When the telescopic tube 218 and the sealing socket 217 are perpendicular, control the small electric motor 219 to drive the telescopic tube 218 to insert into the sealing socket 217 so that the liquid supply tank 201 and the liquid receiving tank 202 are connected. If the telescopic tube 218 and the sealing socket 217 are not perpendicular, control the second rotor 211 to increase or decrease the rotation speed until the telescopic tube 218 and the sealing socket 217 are perpendicular, and then the controller 221 controls the rotation speed value of the second rotor 211 to be the same as that of the first rotor 101, so that the liquid supply tank 201 and the liquid receiving tank 202 can be detachably connected, and the liquid cooling medium can be added to the liquid receiving tank 202 without stopping the machine, without affecting the operation of the rotor, and thus the working efficiency can be improved.

[0082] Specifically, for example: when the first rotor 101 starts to rotate, the rotation speed measuring device 227 obtains the rotation speed value of the first rotor 101 as 300 revolutions per minute, and the controller 221 controls the rotation speed value of the second rotor 211 to be also 300 revolutions per minute. The camera 212 takes videos of the telescopic tube 218 and the sealing socket 217 and calculates whether they are perpendicular. When they are perpendicular, the controller 221 controls the power output rod of the small electric motor 219 to extend and drive the telescopic tube 218 to insert into the sealing socket 217, and the liquid supply tank 201 and the liquid receiving tank 202 are connected. In this way, the liquid cooling medium in the liquid supply tank 201 enters the liquid receiving tank 202, and the liquid receiving tank 202 is connected to the hole for the liquid cooling medium of the first rotor 101 to cool the first rotor 101. If the telescopic tube 218 and the sealing socket 217 are not perpendicular, the controller 221 controls the second rotor 211 to increase or decrease the rotation speed until the telescopic tube 218 and the sealing socket 217 in the taken video are perpendicular, and then controls the rotation speed value of the second rotor 211 to be the same as that of the first rotor 101 so that the telescopic tube 218 can be inserted into the sealing socket 217.
