Description

Technical Field

[0001] This utility model relates to the field of vertical permanent magnet motor technology, and in particular to a vertical permanent magnet direct drive motor. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field, which acts on the rotor to create magnetoelectric torque.

[0003] There are many types of motors, but the vertical permanent magnet direct drive motor mainly converts electrical energy into electromagnetic energy, and drives the shaft to rotate through magnetic force. The vertical permanent magnet direct drive motor consists of a housing, an upper end cover, a lower end cover, a stator winding, and a rotor.

[0004] Vertical permanent magnet direct drive motors generate a certain amount of heat during use. Traditional heat dissipation methods typically use heat sinks, which are generally ineffective and require air circulation to help dissipate heat. Excessive temperature can affect the long-term safe and stable operation of the permanent magnet direct drive motor.

[0005] Therefore, it is necessary to provide a vertical permanent magnet direct drive motor to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a vertical permanent magnet direct drive motor, which solves the problem that heat dissipation through heat sinks is ineffective and that excessively high temperatures can affect the long-term safe and stable operation of the permanent magnet direct drive motor.

[0007] To solve the above-mentioned technical problems, the vertical permanent magnet direct drive motor provided by this utility model includes: a mounting bracket;

[0008] A permanent magnet motor is mounted on the top of a mounting frame. The permanent magnet motor includes a lower end cover, heat sinks, and an upper end cover. Each of the lower and upper end covers has an installation port at one adjacent end. Heat sinks are provided with heat dissipation pipes. One end of each heat dissipation pipe is fixedly connected to a delivery pipe, and the other end is fixedly connected to a return pipe. A cooling fan is installed at the bottom of the inner wall of the upper end cover, and a filter cover is installed on the top of the upper end cover by a mounting bolt.

[0009] The mounting plate is fixedly connected to the outer surface of the lower end cover on one side. A cooling liquid tank is installed at the bottom of the mounting plate, and a protective shell is installed at the top of the mounting plate near the back. A delivery pump is installed inside the protective shell.

[0010] The permanent magnet motor also includes internal stator windings, a rotor, and a structure on the upper end cover. Multiple heat sinks are mounted between the upper and lower end covers via a housing. These heat sinks are spaced apart and form an arc shape. Cooling pipes are wound between every two heat sinks, with the bent sections located inside the mounting openings, thus allowing for a change in shape. (See reference for details.) Figure 3 or Figure 5 The other end of the delivery pipe is fixedly connected to the outlet of the delivery pump, and the other end of the return pipe is fixedly connected to one side of the cooling liquid tank. The mounting bolt is installed at the bottom of the inner wall of the upper end cover.

[0011] Preferably, a stabilizing shell is installed on the top of the inner wall of the mounting bracket, and a rotating shaft is installed at the output end of the permanent magnet motor.

[0012] The pivot point extends through the top center of the mounting bracket.

[0013] Preferably, a connector is installed at the bottom end of the rotating shaft, and a rotating rod is installed at the bottom of the connector.

[0014] Preferably, a plurality of heat-conducting blocks are installed at the bottom of the inner wall of the upper end cover, and the interior of the upper end cover and the top of the heat sink are connected.

[0015] Thermal blocks are made of materials that can conduct heat quickly.

[0017] Preferably, mounting bolts are installed at the bottom of the inner wall of the upper end cover near both sides, and the top of the mounting bolts has threaded holes.

[0018] Compared with related technologies, the vertical permanent magnet direct drive motor provided by this utility model has the following beneficial effects:

[0019] This invention provides a vertical permanent magnet direct drive motor. When the vertical permanent magnet direct drive motor requires heat dissipation during use, the heat dissipation pipe is first passed through the heat sink fins, ensuring a tight fit between the heat dissipation pipe and the heat sink fins. Then, both ends of the heat dissipation pipe are connected to the outlet of the delivery pump and the cooling liquid tank respectively through a delivery pipe and a return pipe. Installation ports for installing the heat dissipation pipe are provided adjacent to the upper and lower end covers. During the use of the vertical permanent magnet direct drive motor, it is only necessary to start the delivery pump to deliver the cooling liquid from the cooling liquid tank to the interior of the heat dissipation pipe, which then dissipates the cooling liquid through the heat sink fins. The heat exchange between the heat sinks allows for rapid heat dissipation, while the cooling fan activates to create airflow between the heat sinks and the outer surface of the heat pipes. This, combined with the cooling pipes, helps to cool the vertical permanent magnet direct drive motor. The structure allows the cooling fan to draw air upwards from the outer surface of the motor, creating airflow. Heat exchange between the heat sinks transfers heat to the cooling fluid inside the heat pipes, improving the motor's cooling efficiency and preventing high temperatures from affecting its stable operation over extended periods.

[0032] The permanent magnet motor 2 also includes an internal stator winding, rotor, and structure on the upper end cover 202. Multiple heat sinks 201 are mounted between the upper end cover 202 and the lower end cover 203 via a housing. The heat sinks 201 are spaced apart and form an arc shape. A heat dissipation pipe 3 is wound between every two heat sinks 201, and the bent portion of the heat dissipation pipe 3 is located inside the mounting opening 17, thus allowing for a change in shape. (See reference for details.) Figure 3 or Figure 5The other end of the delivery pipe 5 is fixedly connected to the outlet of the delivery pump 18, and the other end of the return pipe 6 is fixedly connected to one side of the cooling liquid tank 7. The mounting bolt 16 is installed at the bottom of the inner wall of the upper cover 202. The inlet of the delivery pump 18 is connected to the back of the cooling liquid tank 7 through a pipe.

[0037] Multiple heat-conducting blocks 14 are installed at the bottom of the inner wall of the upper end cover 202, and the interior of the upper end cover 202 is connected to the top of the heat sink 201.

[0038] The heat-conducting block 14 is made of a material that can conduct heat quickly. The location of the connection between the upper cover 202 and the mounting opening for the heat sink 201 can be referenced. Figure 3 .

[0042] The filter cover 4 is installed on top of the upper cover 202 by bolts.

[0043] The working principle of the vertical permanent magnet direct drive motor provided by this utility model is as follows:

[0044] First, the heat dissipation pipe 3 is passed through the heat sink 201 to ensure a tight fit between the heat dissipation pipe 3 and the heat sink 201. Then, both ends of the heat dissipation pipe 3 are connected to the outlet of the delivery pump 18 and the cooling liquid tank 7 through the delivery pipe 5 and the return pipe 6, respectively. The upper end cover 202 and the lower end cover 203 are respectively provided with mounting ports 17 for installing the heat dissipation pipe 3. During the use of the vertical permanent magnet direct drive motor, it is only necessary to start the delivery pump 18 to deliver the cooling liquid inside the cooling liquid tank 7 to the inside of the heat dissipation pipe 3. The heat exchange between the heat dissipation pipe 3 and the heat sink 201 can quickly dissipate heat for the heat sink 201. At the same time, the cooling fan 15 will start to create air circulation between the heat sink 201 and the outer surface of the heat dissipation pipe 3, thereby cooperating with the heat dissipation pipe 3 to dissipate heat for the vertical permanent magnet direct drive motor.

[0045] Compared with related technologies, the vertical permanent magnet direct drive motor provided by this utility model has the following beneficial effects:

[0046] When the vertical permanent magnet direct drive motor requires heat dissipation during operation, first pass the heat dissipation pipe 3 through the space between the heat sink 201, ensuring a tight fit between the heat dissipation pipe 3 and the heat sink 201. Then, connect both ends of the heat dissipation pipe 3 to the outlet of the delivery pump 18 and the cooling liquid tank 7 via the delivery pipe 5 and return pipe 6, respectively. Mounting ports 17 for installing the heat dissipation pipe 3 are provided adjacent to the upper end cover 202 and the lower end cover 203. During operation, simply start the delivery pump 18 to deliver the cooling liquid from the cooling liquid tank 7 to the heat dissipation pipe 3, allowing the heat dissipation pipe 3 to connect with the heat sink 201. Heat exchange can quickly dissipate heat from the heat sink 201. At the same time, the cooling fan 15 will start to create airflow between the heat sink 201 and the outer surface of the heat pipe 3, which can work with the heat pipe 3 to dissipate heat from the vertical permanent magnet direct drive motor. Through this structure, the cooling fan 15 can draw the air from the outer surface of the vertical permanent magnet direct drive motor upward, thereby creating airflow. Heat exchange between the heat sinks 201 transfers heat to the cooling liquid inside the heat pipe 3, which can improve the heat dissipation effect of the vertical permanent magnet direct drive motor and prevent the vertical permanent magnet direct drive motor from being affected by high temperature during operation for a long time to ensure stable operation.
