带位置传感器控制带。位置传感器控制是在小马达定子上安装位置传感器来检测转子位置而控制定子绕组换向。The position sensors used are electromagnetic (such as reluctance resolver) and photoelectric. Magnetically sensitive sensors are widely used. 2. Sensorless control of small motor without position sensor. It is not directly installed on the stator of small motor.。减速电机采用一种新型密封装置，保护性能好，对环境适应性强，能在腐蚀、湿度等恶劣环境中连续工作。直流。电机的主要类型。In today's industrial field, DC motors are everywhere. From robotics to automobiles, small and medium-sized motors usually adopt the technical characteristics of DC motors, which have a wide range of functions.
