Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Here is a circuit that will output a PWM wave good for varying the speed of a DC motor. Why is this not going to work? How would you fix it? The 555 timer can’t handle that type of load, and it is not ...

This PWM Controller circuit is ideal for controlling small motors with 2A maximum current consumption. For higher currents you need additional cooling for T2 and increase C2 value. This pwm motor ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

Tutorial on ac-motor control based on Clarke and Park transforms. Concepts are presented in stages from top-level through deeper levels of detail. Regardless of their primary field, sooner or later, ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...
