Subject: [Electronics_101] Small DC motors and small ceramic CAPs on them - why?

Hi guys,

I found my R/C car motor and in the meantime also ordered one from
Jameco. Both perform really well and look like they will have enough
torque for PCB drilling - I hope, they are certainly not "overkill".

Anyway, I noticed that on both motors there are two small ceramic caps
between the power terminals. I don't understand why they are there
and what they are doing. Can anyone shed some light on this for me?

Probably to stop sparking on the brushes and commutator that could interfere with radio reception.

Leon
