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 ...

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

Four new type WPM controls provide speed control for 12 or 24 V PMDC gearmotors and motors up to 1/3 hp/250 W. The controls use pulse width modulation (PWM) technology to insure quiet operation, low ...
