[0039] All features disclosed in this specification, or all steps of any methods or processes disclosed in this specification, can be combined in any combination, except combinations where at least some of such features and / or steps are mutually exclusive.
[0040] Any feature disclosed in this specification, unless stated otherwise, can be replaced by any equivalent or similar feature, or any equivalent or similar feature capable of achieving the same result. That is, unless stated otherwise, each feature is one example only of a generic series of equivalent or similar features.
[0041] As shown in Figure 1 and Figure 2 , the aim is to improve the degree of automation, accuracy and efficiency of motor testing, and reduce the interference of human factors on test results. The device mainly consists of a drive motor 1, a fixing mechanism, a testing mechanism, an upper computer and a data processing system, and can comprehensively detect the operating parameters of the motor to be tested 3, including speed, torque, temperature, current, voltage, etc., to ensure the comprehensiveness and accuracy of the test data.
[0042] The drive motor 1 of the device is used to provide power to drive the motor to be tested 3 for testing. The drive motor 1 is connected to the input end of the motor to be tested 3 through a coupling, which can ensure the power transmission between the drive motor 1 and the motor to be tested 3, and can withstand the load and torque generated during testing. The drive motor 1 drives the motor to be tested 3 to run in the set mode, thereby completing various performance tests.
[0043] In order to ensure that the motor to be tested 3 is stable and fixed during testing, the fixing mechanism plays a key role. The fixing mechanism includes a support frame 4 and a clamping plate 2. The support frame 4 stably supports the motor to be tested 3 and ensures that it remains stable throughout the testing process, preventing displacement or deviation due to vibration or other external forces. The clamping plate 2 further fixes the motor to be tested 3 on the support frame 4, ensuring that the position of the motor to be tested 3 does not change during testing. One end of the clamping plate 2 is provided with a shaft pin 8, and the other end is a movable end. After the clamping plate 2 is clamped, the movable end is inserted and tightened with a fastener to complete the locking.
[0044] During the test process, the test mechanism plays a crucial role. The test mechanism integrates multiple sensors to detect key performance parameters of the motor under test 3. First, a wheel speed sensor is installed at the output end of the motor under test 3 to monitor the wheel speed of the motor drive part in real time. Wheel speed is a key parameter for evaluating the working efficiency and running state of the motor, and can provide the power output level of the motor during operation.
[0045] Next, the 5 is fixedly installed on the output end of the motor under test 3 through a torque mounting bracket 6, and is connected with the output shaft of the motor under test 3 through a shaft coupling. The function of the torque speed sensor 5 is to accurately detect the torque output by the motor, which is crucial for judging the load capacity and performance stability of the motor. In this process, the torque speed sensor 5 can transmit the output torque signal and speed signal through the shaft coupling for real-time monitoring of the torque and speed of the motor. The torque and speed of the motor are key indicators of its working efficiency and power output, and the torque speed sensor can provide accurate torque and speed data to help judge the running performance of the motor under different loads, thereby providing real-time feedback on the running state of the motor.
[0046] The temperature sensor is installed inside the motor under test 3, mainly for monitoring the temperature change of the motor during operation. The working temperature of the motor is one of the important factors affecting its performance, and excessive temperature may cause the motor to overload or damage, so the temperature sensor can be used to monitor the temperature control state of the motor in real time, ensuring that the motor works within a reasonable temperature range.
[0047] In addition, current and voltage sensors are installed inside the motor under test 3 to detect the current and voltage of the motor under test 3. These sensors are important for the energy efficiency and performance evaluation of the motor, and changes in current and voltage can reflect the power consumption, load condition and performance of the motor under different working conditions.
[0048] The host computer is the core control unit of the device, responsible for the control, data recording and processing of the test process. Through the serial CAN interface, the host computer is connected with the motor under test 3 and various sensors for data communication, ensuring real-time monitoring of various data during the test process and transmitting them to the host computer for processing. The control unit can set the working mode and test parameters of the motor through the host computer interface, and start the motor for automatic testing. The host computer can receive data from the sensors and transmit them to the data processing unit for analysis and storage.
[0049] During the test, the host computer controls the motor 3 to run under different working conditions according to the set test parameters and monitors the test data in real time. The data processing unit processes the data from various sensors and generates corresponding test results. The test results are presented to the operator through the display unit for viewing and torque speed sensor. All test data and results are stored in the storage unit for subsequent query and analysis.
[0050] To improve the load adjustment capability of the test, the device also integrates a magnetic powder brake 7 connected to 5 through a shaft coupling. The main function of the magnetic powder brake 7 is to simulate different working conditions by adjusting the load, so as to verify the performance of the motor under various working conditions. The magnetic powder brake 7 can adjust the motor load during the test to ensure that the data during the test is more comprehensive and accurate
[0051] The entire test process can be automated according to the preset test plan. The operator only needs to input the corresponding test parameters on the host computer interface, and the system can automatically start the drive motor 1, collect various data through the sensor, and process, display and store the data through the host computer. The entire process reduces human intervention, improves test efficiency and accuracy, and ensures comprehensive and accurate evaluation of motor performance indicators.
[0052] After completing the test, the host computer will generate a detailed test report including the motor performance indicators, test date, running status and test results. The report will be saved in the storage unit and can also be exported for further analysis or archiving as needed.
[0053] The motor automatic test device provided by the embodiment can greatly improve the efficiency and accuracy of motor performance testing, while reducing errors in manual operation. Through intelligent control and data processing, the performance of the motor can be comprehensively and real-time detected, ensuring the stability and reliability of the motor quality.
[0054] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions without creative labor should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
