On the Application of Hall Sensor in Speed Measurement for DC Stepper Motor

Article Preview

Abstract:

This paper describes the working principle of hall sensor and its application in DC stepper motor. It designs a speed detection system for DC stepper motor based on P89V51 Single Chip Microcontroller (SCM), i.e. hardware circuit diagram and software flow chart. It utilizes Hall elements to complete the conversion from speed to pulse and then process the pulse signal to get the quantity of pulse during unit interval. By means of comparison of test and theoretical data, it indicates that the speed measurement system is satisfactory for application in reality.
