Speed control in a direct current motor with pulse width modulation (PWM) offers several advantages. Firstly, PWM allows for precise and accurate control of motor speed, enabling the motor to operate at different speeds as required by the application. Secondly, PWM control is energy-efficient as it regulates the amount of power delivered to the motor, resulting in reduced energy consumption and cost savings. Lastly, PWM control helps in reducing motor wear and tear by minimizing sudden changes in speed, leading to improved motor longevity and reliability. **
