“HW-687 is one easy module for adding speed regulation to your next DC motor-based project. It is a simple pulse-width–modulated speed controller providing smooth control with almost no jerks. There ...

The DPW Series pulse-width-modulated dc motor-speed control designed in a compact SMT package. The RoHS-compliant models are rated from 2 to 10-A continuous output at 120/240 Vac. Machine Design ...

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 ...

The 555 timer IC is a handful of active components all baked into one beautifully useful 8 pin package. Originally designed for timing purposes, they became ubiquitous parts that can achieve almost ...

A solid state PWM switching device, the MMP20A-12V-RSP motor speed control module includes a built-in reversing switch and speed adjust potentiometer. The module provides bi-directional, open loop, dc ...

Recently, I found an interesting fan motor module in a web shop and grabbed a couple of them for nothing. At the heart of the module is an eight-pin L9110 DC motor control chip from ASIC (www.asic.net ...

motor control based on a six-step commutation sequence; detection of the magnetic angle of the rotor, to perform the commutation at the correct angle (each step corresponds to an angle of 60 degrees); ...
