By closing specific pairs of switches simultaneously, we can reverse the polarity of the voltage applied to the motor, thereby altering its rotation direction. This circuit comprises four switches arranged in an H-like pattern with the motor at the center. To change the spinning direction, we utilize an H-Bridge circuit. Now, let’s address the issue of controlling the rotation direction of the DC motor. H-Bridge – For controlling rotation direction A higher duty cycle results in a greater average voltage, leading to high-speed motor operation, while a lower duty cycle reduces the average voltage, causing the motor to run at a slower speed. PWM involves sending a series of ON-OFF pulses to the motor, effectively adjusting the average input voltage. To achieve this, we employ a technique known as Pulse Width Modulation (PWM). PWM – For controlling speedĬontrolling the speed of a DC motor is a fundamental requirement in many applications. DC Motor Controlling can be achieved by combining these two techniques. In order to have a complete control over DC motor, we have to control its Speed and Rotation Direction.
