DC Motors Disc Capacitor How To Select Size ?(+Connection)
- For circuit protection...
+ Is there any other protection you can use ?

I have:
Speed+Direction Changing Unit:
2x18650 Batteries=7,4V
PWM+Potentiometer (LINK TO SITE)
2x On-Off-On switches
Mini Digital Voltmeter

Motors DC: 2 Pieces: 6V; 0.04A

Do I Need Something Else To Protect the Components ???
(Suggestions So I Won't Brake Anything When Building)
Thanks

 

Ehen using small hobby motors anything from about .01 to .1uF(10-100nF) directly across the pos. and neg. motor wires is standard. Rate them at 16 v0lts or more. The most commonly used are .1uF @ 50V disk capacitors. You can use 2 caps, one from each terminal to the case for even better filtering of RF.
