Aim:The main aim of PC BASED SYNCHRONIZING AND SPEED CONTROLLING OF DC MOTOR project is to control the speed of DC motor and on/off the motor using PC.
Description: If the voltage is varied, the motor would not be able to deliver the rated torque when operated at voltages lower than its recommended operating voltage. This problem can be over come by using PWM technique. PWM stands for pulse width modulation. The speed of the DC motor controlled by PC. This data is transferred to Micro controller serially. Here in Microcontroller produce a square wave with variable duty cycle. The variable duty cycle in effect dictates the speed of the motor. Here the fundamental frequency of the square wave is constant for only the ON and OFF, time is appropriately manipulated. More ON time will cause the motor to run at higher speeds. As the ON time is reduced and proportionally the time is increased, the motor would slow down.
Typical 50% duty cycle: Equal On time and off time.
