Abstract

A microcontroller based DC motor control unit was developed to control the user specific speed of a DC motor. The controlling unit consists of a GMR sensor along with indigenously developed planer magnetic encoder and an embedded system consisting of a motor driving unit to drive the loads up to 4 Amps. The software algorithm was developed to ramp up the motor speed to user specified value entered through keyboard. A magentic current sensor is used, which acts as a current limiting switch for preventive measure. The efficiency of the embedded system was verified with NI data acquistion software developed for controlling these motors and the output was observed to have deivations less than 2%.
