The horizontal conveying structure on the test rack 31 transports the motor test platform 1 to the corresponding test position. After the motor test is completed, the horizontal conveying structure on the test rack 31 transports the motor test platform to the vertical unloading structure 41. The vertical unloading structure 41 then transports the motor test platform 1 on each row of the test racks 31 to the first horizontal unloading structure 42 to complete the unloading.
