Is it possible to add a speed control to this electric fan ? If so I will appreciate any quot; linkquot; with information of the kind of controller I may need. I need it running at variable speeds.
You need to specify the type of motor you are going to use. Every different type needs a different approach to speed control. If you want to use a universal motor then continuous speed control of a universal motor running on AC is very easily accomplished using a thyristor circuit, while stepped speed control can be accomplished using multiple taps on the field coil. In the case of synchronous motors you might not be able to change the motor speed. As for connecting the wheel. You might be able to use chain drive. Sprockets on both wheel and motor shaft and link with chain. Possibly you could use a belt. You would need something like a vee pulley on each.
Because it is a AC motor you will need a one phase inverter! Just google for one phase inverters and see one that fit with the power and voltage of your fan!!! good luck!!!
