The shaft rotation status detection circuit: there are some electromagnetic sensors around the shaft, these sensors make the spring switch to turn on and off. When the switch is at the on position, the monostable multivibrator is triggered, the Q outputs the H, the operating is normal, Q maintains the H state. When the shaft stops turning, the switch can not turns on and off, after the Cx and Rx confirm the time constant, the output of Q is L.
