DC MOTOR HAVING ROTARY SENSOR

摘要

PURPOSE: A DC motor having a rotary sensor is provided to detect the number of revolutions by using a magnet and a hall sensor. CONSTITUTION: A stator and a rotator are fixed to the inside of a housing(100). A rotary shaft is coupled with the rotator. A sensor plate(120) is installed at a center of a projected part of the rotary shaft(110). A plurality of sensing blocks(130) are installed on the sensor plate(120). A cover(101) is installed on upper portions of the sensing blocks(130). The cover(101) is coupled with the housing by using a combination screw(102). A magnet, the sensing blocks(130), and the sensor plate(120) are formed with one body. A main substrate(150) is installed at the outside of the sensor plate(120). A plurality of outer hall sensors(200) are installed at a lower part of the main substrate(150). A plurality of inner hall sensors(210) are installed at a support substrate(160).
