Motor Control Projects

Abstract

Brushed DC (BDC) motors are low-cost, easy-to-drive electric motors that are used in many movement-based applications. These motors have two terminals and the voltage is applied across these terminals. The speed of the motor is directly proportional to the amount of the applied voltage. The direction of rotation can be changed easily by changing the polarity of the voltage across the terminals. The torque produced by the motor shaft is directly proportional to the current flowing through the motor windings. Stepper motors are used in applications where it is required to control the motor shaft position accurately. In this chapter projects are given to show how Mbed-based programs can be developed to control ...
