This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains in depth all about pwm so you can understand it easily. #JoyplanesRC #pcb #J ...

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, ...

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

Once upon a time (2017), I published a simple design idea for filtering and attenuating PWM DAC output ripple that I’d found very useful for over a decade. It works by passive summation of the PWM ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

In designing a simple spectroscopy setup, we needed to synchronize the speed of a small, inexpensive dc motor precisely to 6000 rpm (100 Hz). Our first idea was to take a phase-frequency detector type ...

The microprocessor allows for custom programming to fit specific OEM requirements, potentially eliminating the need for a PLC and supporting devices. Drives can be easily programmed for use in the ...

voltage. Often a passive single-pole RC filter will satisfy design requirements, but this approach typically suffers from several drawbacks including slow response time, noisy results, and having an ...
