The frequency of PWM needs to be controlled precisely to get the best motor performance
The better efficiency of the PWM drive increases battery life and reduces heating in electronic components that extend many
applications using miniature brushed DC motors require motors to operate at more than one load point or through specific
load cycles. When using a PWM source, the circuit sees Ohmic resistance and inductance due to frequent switching.
In addition, a back EMF equivalent to the motor characteristics and speed is generated across the terminal. This complicates
the PWM circuit when designing it for a specific application, as not only the duty cycle but the frequency of PWM needs
to be controlled precisely to get the best motor performance.
