[0002] Existing motor test devices are usually used for motor performance testing and related experiments, but their designs have obvious limitations in terms of flexibility and ease of operation. In order to adapt to motors of different specifications and models, these devices need to adjust the clamping structure through complex disassembly and assembly steps. The whole process is not only time-consuming and labor-intensive, but also significantly reduces the test efficiency. In addition, users often need to manually adjust or replace parts to complete the test preparation. This manual operation method increases the workload and is prone to test failure or equipment damage due to operational errors. In practical applications, motors usually need to operate under different load conditions to verify their performance. However, existing test devices are limited in load simulation capabilities. Most devices can only provide basic fixing functions and cannot flexibly adjust the clamping force to meet the test requirements under different load conditions. This design limits the scope of application of the test device, making it difficult to fully reflect the operating performance of the motor under real working conditions. Especially when simulating special loads or complex operating conditions, existing devices lack flexibility and effective means, which may lead to deviations between the test results and the actual working conditions.
