Description

Technical Field

[0001] The invention relates to the technical field of permanent magnet motor assembly, and in particular to a water-cooled permanent magnet motor. Background Art

[0002] Permanent magnet motor is a synchronous motor that generates a synchronous rotating magnetic field by excitation of permanent magnets. It is composed of stators, rotors, end covers and other components. It has the characteristics of small size, light weight, good dynamic performance, high operating efficiency, high power factor, good reliability, etc. However, when using permanent magnet motors, certain heat dissipation measures need to be taken to reduce the temperature inside the permanent magnet motor, ensure the insulation performance of the motor windings, avoid the phenomenon of permanent magnet demagnetization, and thus extend the service life of the motor. Common motor cooling types include air cooling and water cooling. Compared with air cooling, water cooling has strong heat dissipation capacity, good cooling effect, and low noise.

[0003] Existing water-cooled motors are cooled by embedding cooling pipes in the interlayer between the shells, and the inlet and outlet water pipes are installed on the side of the motor, which requires side space. After a certain period of use, scale will form inside the cooling pipe, resulting in poor heat dissipation, so the cooling pipe needs to be replaced regularly. When replacing the cooling pipe, the motor needs to be disassembled, which is cumbersome and requires shutting down the motor. It cannot adapt to scenarios where some motors do not stop (such as the glass manufacturing industry).

[0004] Therefore, it is necessary to invent a water-cooled permanent magnet motor, which can replace the cooling pipe without shutting down and disassembling the motor, and can save side space so that the motor can be installed in a smaller space. Summary of the invention

[0006] Furthermore, the frame is provided with a first cooling channel liquid inlet and a second cooling channel liquid inlet connected to the liquid inlet pipe, and a first cooling channel liquid outlet and a second cooling channel liquid outlet connected to the liquid outlet pipe; The on-off switching assembly includes two cooling pipe one on-off pipes slidably mounted on the bracket and intermittently connected to the connector one, two cooling pipe two on-off pipes slidably mounted on the bracket and intermittently connected to the connector two, a switching plate one fixedly mounted on the cooling pipe one on-off pipe and elastically connected to the bracket, and a switching plate two fixedly mounted on the cooling pipe two on-off pipes and elastically connected to the bracket; The first on-off tube of the cooling pipeline is provided with a pair of cooling pipeline interfaces that are intermittently connected to a cooling pipeline liquid inlet or a cooling pipeline liquid outlet; the second on-off tube of the cooling pipeline is provided with two pairs of cooling pipeline interfaces that are intermittently connected to a cooling pipeline liquid inlet or a cooling pipeline liquid outlet.

[0007] Furthermore, the on-off switching assembly also includes a prying rod 1 rotatably connected to the switching plate 1, and a prying rod 2 rotatably connected to the switching plate 2.

[0008] Furthermore, a sealing ring 1 for intermittently sealing a liquid inlet of a cooling pipe or a liquid outlet of a cooling pipe is installed at a position on the on-off pipe of the cooling pipe 1, which is located on one side of a pair of interfaces of the cooling pipe; a sealing ring 2 for intermittently sealing a liquid inlet of a cooling pipe or a liquid outlet of a cooling pipe is installed at a position on the on-off pipe of the cooling pipe 2, which is located on one side of a pair of interfaces of the cooling pipe.

[0009] Furthermore, a first limiting column for fixing and connecting two folded pipes together is provided on several folded parts of the cooling pipe one; a second limiting column for fixing and connecting two folded pipes together is provided on several folded parts of the cooling pipe two; The limiting assembly includes a buckle that is slidably installed on the outer support shell and intermittently clamps the limiting column one or the limiting column two, a pushing block that is slidably installed on the outer support shell and intermittently lifts the buckle, and a spring piece that is fixedly installed on the outer support shell and clamps the buckle.

[0010] Furthermore, the pushing block corresponding to the buckle for clamping the limiting column one is fixedly connected to the sliding frame one slidably installed on the outer support shell; the pushing block corresponding to the buckle for clamping the limiting column two is fixedly connected to the sliding frame two slidably installed on the outer support shell.

When replacing the cooling pipe, there is no need to disassemble the permanent magnet motor body. The cooling pipe can be replaced without stopping the permanent magnet motor body. When one set of cooling pipe one or cooling pipe two is removed, the other set of cooling pipes can still work normally to cool the permanent magnet motor body. In addition, the liquid inlet pipe and the liquid outlet pipe are not installed on the side of the permanent magnet motor body, which effectively saves the side space and enables the permanent magnet motor body to be installed in a smaller space.

[0016] 2. The present invention is also provided with a cooling pipe removal mechanism for assisting in removing the cooling pipe. The operation is simple and there is no need for the operator to directly contact cooling pipe one or cooling pipe two, thus avoiding the operator from being scalded.
