This high torque gear motor is equipped with a hall effect encoder to help users adjust the speed of the motor. Even though this is a high torque motor, the sound it generate is very low! There are 2 outputs on the encoder where the first output can monitor the speed and direction of the motor and the second output can adjust the speed in a closed loop circuit.
The encoder output 2 signals with 90 degree phase difference. There are 334 pulses on each of the signal for every 360 degree cycle. With rising & falling edge, you can get a total of 1336 signals for every revolution, with an interval of 360/1336=0.2694 degree.
