Hey guys , just asking , for AC motors , we have to control the voltage in order to control the speed , At first I thought of using SCR but SCR is a manual device as i mean it is an analogue device. Is there any other equipments to control the voltage, I using a PIC microcontroller but i run out of ideas controlling the speed of an AC motor . How about voltage regulator or inverters ?
Hi Nigel,
I have opened up a Table fan, they have a few switches which control the output of the voltage, . But i am clueless about how does a remote control fan controls its speed . I just want to control my fan remotely the speed.
