碩士 === 健行科技大學 === 機械工程所 === 101 === The non-contact type application of the permanent magnetic and Hall-effect sensor as well as contact circular scale gauging rotary system are introduced in this work. The main component of the angular position estimation system is Hall-effect sensor. Precise resolution up to 200 steps per cycle by the sensor can be provided by the Hall-effect sensor applied on the step motor. The circular scale is used to detect the accuracy of the angle gauge and to compare the results of Hall-effect sensor. The Hall-effect sensor can be applied no lower-cost hardware and software technology. The angle of the system can be measured with high precision output of the corner. It is suitable for high vibration, high temperature, high humidity, and other special operations of working environment.
