摘要： A stepping motor has a cylindrical case that houses a motor stator and a sensor stator. The motor stator and the sensor stator are located at the opposing ends of the case. A motor rotor and a sensor rotor are mounted on a shaft and face the motor stator and the sensor stator, respectively. The sensor rotor and the sensor stator together form a rotational position sensor. The incorporation of the rotational position sensor in the case reduces demand for installation space. The gap of approximately 40 to 50 microns between a motor stator core and motor rotor cores is achieved by accurately locating the motor stator and the motor rotor. The case is sealed by the front flange and the rear cover, thereby, unfailingly preventing the invasion of contaminating foreign matter such as dust particles, oil, moisture etc.
