[0002] A motor drag test bench is a device used to evaluate and test motor performance. It simulates the load conditions of a motor under actual operating conditions. By performing dynamic or static drag tests on the motor, key parameters such as starting torque, operating smoothness, overload capacity, and thermal stability can be verified. This type of testing is extremely important for motor manufacturers.

[0003] Existing motor drag test benches generally fix the test motor by fixing the base plate of the test motor to the upper end of the test bench when in use. However, the test motor needs to be aligned with the load motor and then connected to the torque sensor. However, large motors are large in size and heavy in weight, which makes it very troublesome to move the motor, making the installation and removal of the test motor very time-consuming.

[0004] Therefore, those skilled in the art provide a combined motor drag test bench to solve the problems raised in the above background technology. Utility Model Content

[0009] Furthermore, two first fixing blocks are fixedly provided at the front and rear ends of the load motor, and first fixing screws are threadedly sleeved on the upper ends of the four first fixing blocks.

[0010] Furthermore, a torque sensor is provided on the threaded sleeve in the middle of the main body, and second fixing blocks are fixedly provided at the front and rear ends of the torque sensor.

[0011] Furthermore, two sliding grooves are provided on one side of the upper end surface of the sliding plate, and two mounting plates are fixedly provided in the middle of the upper end surface of the sliding plate.
