Test structure of motor rotor

The utility model discloses a test structure of a motor rotor, which relates to the field of motor rotors and comprises a test board, an adjusting mechanism is mounted on the inner side of the test board, and a lifting mechanism is welded at the top end of the outer side of the adjusting mechanism. According to the utility model, through the arranged adjusting mechanism, when the motor rotor is tested, according to the length of the motor rotor, the positive and negative screw rods are rotated through the rotating disc, so that the movable sleeves on the outer side walls of the positive and negative screw rods are driven to adjust the distance, and then the two ends of the motor rotor are respectively inserted into the fixed slotted holes in the inner sides of the corresponding placing racks; the motor rotor is manually rotated, so that whether abnormal resistance or blockage exists in the rotating process of the motor rotor or not is known, the motor rotors with different lengths can be tested, and the motor
