I think the speed controller is built to control a three-phase motor from a single phase power line.

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-second of electrons at 1 volt. A 1-farad capacitor would typically be pretty big.

The adhesive is needed to prevent the capacitor vibrating (the leads acting like a spring) and moving around when device is subject to external forces. I'm looking for something like DOW CORNING 744 WHITE Adhesive, RTV Silicone or WACKER Silicone Adhesive Sealants (WACKER Silicone Adhesive Sealants - Intertronics) Take a look at these options.
Ya, I tried hot glue before I posted. As soon as the caps (or the board in general) warms up the least little bit, the hot glue releases. Be aware that not all silicone sealants are compatible with electronics. If I remember correctly, the ones with a strong acetic acid smell are a no-no, because it will cause corrosion.
Hi Michael, I think we misunderstood each other. The capacitors are leaded components that will be soldered through holes in PCB. The adhesive is needed to prevent the capacitor vibrating (the leads acting like a spring) and moving around when device is subject to external forces.
It has a strong vinegar like odour that can be acidic and not good for copper. Not so good in heat applications. If anything, a polyurethane sealant would work well. Google Sicaflex Just do any of this gluing as a very last stage... after final testing, because it will be difficult to unglue and this stuff may take a day or more to fully cure.
