Decoupling Capacitor Calculations: What Size Should You Use
All capacitors store charge in equilibrium when connected to a DC voltage source; the plates in the capacitor charge up and hold a total amount of charge equal to Q = CV. If V fluctuates or drops out a little bit, then some of that charge Q is released and delivered to the load, just like a small battery.

How do I decide what capacitor to use in a circuit?
I am using a voltage regulator, and to get cleaner power, the datasheet recommends using a 0.33uF capacitor. However, it doesn''t say what type it wants. Stupidly, I went out and bought a 10 pack of 0.33uF 50V Radial Electrolytic Capacitors.After looking up on this site, I found that the symbol means that it is a unpolarized capitator. ...

The voltage can be smoothed with a capacitor only after the inductance - in your case impossible. The motor can exhibit torque ripple due to the current ripple and not due voltage ripple, so the capacitor is never needed.
How Capacitors Work
A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amp represents a rate of electron flow of 1 coulomb of electrons per second, so a 1-farad capacitor can hold 1 amp

How do I size the output capacitor for a DC bench power supply?
Replace your "big" (45 V) DC source with a source that has a pulse definition, i.e. one that starts at 0 V and steps to 45 V within a short time (say 10...100 ns), after a short time (say 1 µs). That way, all the capacitors will be initialized for an unpowered circuit, and you see your regulator doing it''s very best to charge the output capacitor.
