The use of geared motor modules, installed in automatic doors to optimize the stability, efficiency, and manufacturing costs related to automatic door opening and closing, has been attracting scientific attention. Generally, signal processing and the sensor circuit board inserted in the geared motor have been widely used in optical systems. However, the optical system is disadvantageous in that it is susceptible to external shock, humidity, and dust. In this article, a magnetic impulse ring‐based motion detection circuit board simpler in structure than the existing optical systems, having excellent durability against external environments, and can be miniaturized is proposed. Experimental results show that the proposed module based on Hall sensor has RPM (revolution per minute) detection characteristics more than 6 dB better than conventional optical module. Also, the proposed module has about 14 dB excellent power consumption than existing optical modules, thus its applicability is confirmed. © 2019 Institute of Electrical Engineers of Japan.
