Furthermore, in order to prevent the conventional iron bearing from generating suction force to the magnet on the rotor, the ceramic deep groove ball bearing 16 is selected as the bearing, and the ceramic deep groove ball bearing cannot generate suction force to the magnet, so that the accuracy of dynamic balance test is ensured.
The space adjustment structure between the first support frame 1 and the second support frame 5 specifically comprises: the base 2 is provided with a first chute 3 and a limiting groove 4, the lower end of the second support frame 5 is matched with the first chute 3, the limiting groove 4 is communicated with the first chute 3, a limiting bolt 6 is arranged in the first limiting groove 4, and the limiting bolt 6 is in threaded connection with the lower end of the second support frame 5.
