The time interval of sensor from the pole S1 to the pole S2 for detecting third magnet 122 that detect the second magnet 121 is all T1, then
It indicates that idler wheel 1 is always maintained to rotate clockwise, does not change the direction of motion.
As shown in Figure 10, when idler wheel 1 becomes to rotate counterclockwise by rotating clockwise, in a swing circle T, Hall
Sensor from detect the pole S1 of the second magnet 121 to the pole S2 for detecting third magnet 122 time interval by original T1
Become T2, thus Hall sensor judges that the direction of motion of idler wheel 1 is to become counterclockwise from clockwise, then hall sensing
