In the Triac based electronic ac dimmer fan regulator circuit there are mainly three components used. This is 220v ac dimmer circuit diagram based on capacitor, in the capacitive Dimmer/regulator no noise.

In this post I have explained a few circuit diagrams for building AC motor speed controller circuits using back EMF concept. Working Principle of AC Motors So now, all those home type appliances like electric drill machines, sander machines, sewing machines, food mixer machines, etc. they all are mostly using that AC motor which is […]

A simple electronic ceiling fan regulator circuit using a triac and a diac is a common type of circuit which is used to control the speed of a ceiling fan. This circuit basically works using phase control principle, in which the voltage supplied to the fan motor is varied by controlling the firing angle of […]

In this post we investigate what's a BLDC motor and subsequently I have explained regarding the design of a sensorless BLDC motor driver circuit. BLDC CPU Fans Seen those fast moving fans in CPUs, voltage stabilizers, DVD players, and other similar equipment, which work with utmost efficiency, consuming minimum space, current and yet are able […]
