1000WACMotorSpeedController
This triac based AC motor speed controller circuit is designed for controlling the speed of AC motors like drill
machines, fans, vacuums, etc. The speed of the motor can be controlled by changing the setting of P1 potentiometer.
The setting of P1 determines the phase of the trigger pulse that fires the triac. The circuit incorporates a self
stabilizingtechniquethatmaintainsthespeedofthemotorevenwhenitisloaded.
Forexample,whenthemotorofthedrillmachineissloweddownbytheresistanceofthedrilledobject,thecounter
EMF of the motor also decreases. This results to a voltage increase in R2P1 and C3 causing the triac to be triggered
earlierandthespeedincreasesaccordingly.
