How to use capacitor to slow down the fastest

Does a bigger inductor slow down a capacitor?

So an inductor in series with the capacitor, and perhaps in parallel with a diode if you want to control the discharge only (and not the charge up), will slow down the early discharge rate of a capacitor. A bigger inductor will slow down the rate more. Yes, easiest way to do it!

Why do I need a capacitor?

The post you refer to says use a capacitor because at ac a capacitor has impedance. This can reduce the voltage to the motor. This also causes a phase shift. This is a not a great way to do it but is quick and efficient.

Do capacitors provide rpm?

Capacitors do not provide the RPM, this is decided by the frequency of the supply in a induction motor, the capacitor provides the correct phase shift in the split phase winding in order to provide the optimum phase angle relative to the supply. Max.

Which capacitor should I use?

So one logical thing to try will be to put another capacitor in series with the whole system. The capacitor to try will be one intended for use with AC motors, Rated for probably 400 volts AC and several microfarads. Another option is to try a lower voltage.

How does a capacitor discharge through a fixed resistor?

As your capacitor discharges through a fixed resistor it's voltage will drop, and current drop proportionately, not logarithmically, but not directly either. We know that lower current, obtained by either higher resistance or lower voltage, will result in a slower discharge of the capacitor. We obviously need values to make these calculations.

Can a capacitor circuit control a ceiling fan speed?

A Google of "fan speed capacitor circuit" will bring up more examples of how using capacitance fan speed is controlled. Just remember trying to start a ceiling fan at too slow of a speed can have bad results. The circuit you have can be modified to work with the switch you have. Hi Ron, thanks for your note, I understand your point.
