[0027] Furthermore, the motor rotor is placed on the induction component 2, and the transmission component 3 is started. The transmission component 3 drives the rotation of the motor rotor. The rotating shafts at both ends of the motor rotor cause the induction component 2 to vibrate, that is, the induction magnetic column 2.1 vibrates, and the induction coil 2.2 will generate an electrical signal. The amplitude of the electrical signal is within the specified range, and the belt is a suitable product.
[0028] More specifically, the induction component 2 includes an induction shell 2.3, a movable groove 2.4, a slide 2.5 and a ring 2.6, wherein the bottom of the induction shell 2.3 is fixedly mounted on the top of the base 1, the movable groove 2.4 is opened on the induction shell 2.3, two slides 2.5 are provided, the two slides 2.5 are slidably mounted in the movable groove 2.4, the slides 2.5 are located in the movable groove 2.4 and slide, the ring 2.6 is fixedly mounted on the bottom of the slide 2.5, and the ring 2.6 is fixedly mounted on the induction magnetic column 2.1.

The rotating shafts at both ends of the motor rotor rotate on the skateboard 2.5. The rotation of the rotating shafts at both ends of the motor rotor is unbalanced or the rotating shaft is in an eccentric position on the motor rotor, resulting in a large vibration amplitude of the skateboard 2.5, which drives the vibration amplitude of the induction magnetic column 2.1 to increase, and the amplitude of the electrical signal generated by the induction coil 2.2 becomes larger, which exceeds the specified range. The motor rotor is an unqualified product.
