INTERFACING: SERVOMOTOR

CHAPTER OBJECTIVES

In this chapter, the reader is introduced to interfacing of servomotors with 8051 microcontrollers. After completion of the chapter, the reader should be able to understand

  • How the servomotor is different from a stepper motor or a DC motor.
  • How does the servomotor works.
  • How to interface a servomotor with 8051.

23.1 | Introduction

Imagine that you are fabricating a robot and presently designing its elbow joint. This joint would be offering only one degree of freedom and rotates through a maximum angle of 180° (Fig. 23.1). If a DC motor or a stepper motor is fitted to perform this duty, it would be underutilized, as they are designed to rotate continuously. In this case, a servomotor is an ideal ...
