[0031] The working principle of the utility model is as follows:
[0032] First, the motor stator to be tested is placed in the stator containing space 130 of the test seat 110. Before starting the test, the protection device 300 (protection plate 310) needs to be moved to the position of the stator test device 100. Once the protection device 300 is in place, the wiring assembly 200 starts to be powered on. After power on, the test bench will perform a series of tests on the stator, which may include electrical performance tests, mechanical performance tests, etc., to evaluate the function and performance of the stator. After the test is completed, the protection device 300 needs to be removed, the power supply is disconnected, and then the stator is taken out, completing the entire test process.
[0033] The utility model motor stator comprehensive test bench, through the rotor device 120 simulates the real working condition of the stator, thereby accurately tests the motor stator, ensures the accuracy and reliability of the detection result.

[0034] In some embodiments, the stator test device 100 further comprises a fastening assembly 140 for fastening the test seat 110.
[0035] The fastening assembly 140 can ensure that the test seat 110 does not displace due to vibration or external force during the test, which can maintain the test accuracy and prevent equipment damage. The fastening assembly 140 can adopt various structures, such as bolts, screws, buckles, wedges, etc.
[0036] Further, the fastening assembly 140 comprises an L-shaped connecting block 150, and the L-shaped connecting block 150 comprises a horizontal part 151 and a vertical part 152, the horizontal part 151 is connected with the rotor seat 121, and the vertical part 152 is connected with the test seat 110.
[0037] The horizontal part 151 is a part of the L-shaped connecting block 150, which is connected with the rotor seat 121. The horizontal part 151 can be fixed by welding, bolt connection or special clamp. The vertical part 152 is another part of the L-shaped connecting block 150, which is connected with the test seat 110. The vertical part 152 of the L-shaped connecting block 150 can be connected with the test seat 110 by bolts, which allows quick disassembly and adjustment of the position of the test seat 110. The L-shaped connecting block 150 provides a stable connection method, which can reduce vibration and displacement during the test.
[0038] In some embodiments, the protection device 300 further comprises a track 320 and a sliding block 330, the sliding block 330 is connected with the track 320, the protection plate 310 is fixed on the sliding block 330, and the sliding block 330 can drive the protection plate 310 to move to the stator test device 100.
[0039] The track 320 is a guide rail fixed on the test bench, which provides a path for the movement of the slider 330. The slider 330 is a moving part connected to the track 320, which slides along the track 320 to drive the shield plate 310 to move. The slider 330 can be moved manually, for example, by a handle or a lever to push the slider 330 along the track 320. In a test bench with a higher degree of automation, the movement of the slider 330 can be controlled by an electric or pneumatic system to achieve automatic movement of the shield plate 310. Through the design of the track 320 and the slider 330, precise positioning of the shield plate 310 can be achieved, improving the safety of the test. Whether it is manual or automatic operation, the movement of the slider 330 and the shield plate 310 is relatively simple and easy for the operator to control.

The automated driving device 340 can reduce manual operation and improve the efficiency of the test process.
[0042] Further, the driving device 340 comprises a lead screw, and the slider 330 is threadedly connected with the lead screw.
[0043] The lead screw provides very precise linear motion because the threads of the lead screw can be converted into linear motion of the slider 330. The lead screw has a self-locking feature that can prevent the slider 330 from sliding without power. The slider 330 can be directly connected with the threaded part of the lead screw, and the slider 330 is pushed to move along the thread by rotating the lead screw. The output shaft of the motor can be directly connected with one end of the lead screw, and the lead screw is driven to rotate by the rotation of the motor.
[0044] In some embodiments, the wiring assembly 200 includes a wiring port 210 and a clamping switch 220 capable of clamping a wire located in the wiring port 210.
[0045] The wire port 210 is the part of the wire assembly 200 for accessing the wire, and the main function of the clamping switch 220 is to clamp the wire located in the wire port 210 to ensure the stable connection between the wire and the wire port 210, preventing poor contact or disconnection caused by vibration or external force. By clamping the wire through the clamping switch 220, the stability of the wire connection can be improved, and electrical failures caused by poor contact can be reduced. The design of the clamping switch 220 makes it more convenient to replace and maintain the wire, without the need for complex tools or operations.
[0046] In some embodiments, the test seat 110 is provided with a positioning strip 160 for cooperating with the groove on the stator.
[0047] The positioning strip 160 cooperates with the groove on the stator to ensure the correct position of the stator on the test seat 110, allowing the stator to be quickly and accurately placed on the test seat 110, improving assembly efficiency. The shape and size of the positioning strip 160 match the groove on the stator to ensure good cooperation and positioning effect. The operator can quickly find the correct position of the stator through the positioning strip 160, reducing assembly time.
