[0018] like Figure 1 As shown, the testing device includes a pneumatic system, a water system, a control system module, and test ports. The pneumatic system is connected to the test ports via pipes and simultaneously to the control system module via lines. The water system is also connected to the test ports via pipes and simultaneously to the control system module via lines. The control system module includes an industrial computer and a gigabit Ethernet switch connected to the industrial computer. The pneumatic system provides the air source for the electric motor performance test. The air source can be general-purpose compressed air from the factory or a separate high-capacity air compressor. The water system provides the water source for the electric motor performance test. The water quality requirement is soft water, including steam condensate and distilled water. The test ports are used to connect the input ports of each electric motor, connecting the testing device and the low-voltage electric motor. Their features are similar to a standard four-hole dental chair connector. The control system module collects some electrical signals from the testing system and allows for electrical control operations during the electric motor performance test. It mainly includes a gigabit Ethernet switch for data exchange and an industrial computer for operator testing, data viewing, and test report generation.

[0019] The gas path system includes pipelines connecting to the gas source and a gas distribution block. The gas distribution block is connected to one end of the pipeline. The pipeline is sequentially equipped with a ball valve A1, a pressure reducing valve A2, a filter A3, and another ball valve A4. Branch pipelines are connected to the gas distribution block, each branch pipeline connecting to a test connection terminal of a test port. Each branch pipeline also connects to the control system module. The ball valves control the opening and closing of the gas path pipelines, the pressure reducing valves ensure the gas path system maintains a suitable pressure value, and the filters filter impurities from the compressed air. The gas distribution block is used for gas distribution at each test port. Its input end connects to the upstream switch ball valve of the gas path, and the 10 output ports are equipped with ball valves A5~A14 and tee interfaces, respectively, connecting to 20 gas connectors at the final test terminal.

[0020] The number of branch pipes corresponds to the number of test ports. Each branch pipe is equipped with a ball valve, which is connected to a gigabit Ethernet switch within the control system module.

[0021] The gigabit Ethernet switch is connected within the ball valve A1 control system module.

[0022] The water system includes a water tank and a distribution block. The water tank is connected to the distribution block via pipes. The pipes are sequentially equipped with a ball valve B4, a water pump B5, a filter B6, and a ball valve B7. An overflow pipe is also provided on the water tank and the pipes. One end of the overflow pipe is connected to the water tank, and the other end is connected to the front end of the ball valve B7 on the pipe. A ball valve B20 is provided on the overflow pipe. Branch pipes are connected to the distribution block. Each branch pipe is connected to the test connection end of the test port. Each branch pipe is also connected to the control system module. An inlet pipe is also connected to the water tank, and a ball valve B1 is provided on the inlet pipe. The ball valve is used to control the opening and closing of the water pipeline. The water tank is used to store test water and includes a magnetic float level gauge B2 and a drain ball valve B3. The water pump B5 is installed before the filter after the water tank and is used to pump water from the tank to each test port. The filter B6 is used to filter impurities in the water. The ball valve B7 is used to control the water inlet of the water distribution block. The ball valve B20 is installed on the side to overflow the water pipeline and prevent the pipeline from being subjected to excessive pressure, which could cause leakage or other problems. The water distribution block is used to distribute water to each test port. Its input end is connected to the upstream switch ball valve B7, and its output end is equipped with ball valves B8 to B17, which are then connected to the 10 water connectors at the final test end.

[0023] Water tank B19 is equipped with a magnetic float level gauge B2. When the water level is lower than the lower limit, the ball valve B1 can be opened through the operation control system module to add water to the water tank. If the water level in the tank is too high, the magnetic float level gauge will output a signal to the operation control system. The next step is to open the ball valve B3 through the operation control system, and the water in the tank will be drained into the sewer.

[0024] The number of branch pipes corresponds to the number of test ports. Each branch pipe is equipped with a ball valve, which is connected to a gigabit Ethernet switch within the control system module.

[0027] Example: Taking "water volume test" as an example:

[0028] Step 1: Connect the 10 assembled electric motors to the 10 test ports in sequence and turn on the power. The assembled electric motors include mobile phone components and the bent mobile phone has been assembled.

[0029] Step 2: Place a measuring cup under the water vapor port of each electric motor-bent handpiece;

[0030] The third step is to open the main inlet ball valve B1 of the water circuit in the operation control system module to test the water flow into the water tank until the appropriate liquid level is reached.

[0031] Step 4: Turn on water pump B5. Water in the tank is pumped out. At this time, ball valve B7 is closed. After passing through ball valve B4, filter B6 and overflow ball valve B20, the water flows back into the tank.

[0032] Step 5: The operation control system module opens the main inlet ball valves A1, A4 and B7 of the air circuit and water circuit respectively. The compressed air is reduced in pressure by the air pressure reducing valve and enters the air distribution block A15 through the filter. The water in the water circuit enters the water distribution block B18 through the ball valve B7.

[0033] Step 6: The operation control system module opens the 10 ball valves A5~A14 at the outlet of the air distribution block A15. Compressed air enters the electric motor from the test port, and the electric motor bends the air outlet to release air.

[0034] Step 7: The operation control system module opens the 10 ball valves B8~B17 at the outlet of water distribution block B18. Test water enters the electric motor from the test port, and water exits from the electric motor through the handpiece hole.

[0035] Step 8: Click on the operation interface to officially start the test timing. After 1 minute, the system will automatically close ball valves A4 and B7, and the test will end.

[0036] Step 9: Measure the water volume in each measuring cup;
