Abstract
A DC motor pulse signal generating device comprising a DC motor including a rotor frame with a magnet for pulse generation and a substrate for supporting the rotor frame. A magnetic sensor is mounted on the substrate for detecting magnetic flux generated from the magnet and outputting a signal. A positioning groove is formed on the substrate to receive the magnetic sensor on a fixed position. Thereby, the gap between the magnetic sensor and the magnet is fixed so that stable pulses are generated, and the height of the center of the magnetic sensor is lowered to the level of the center of the magnet so that magnetic flux is detected most efficiently by the magnetic sensor.
