Hi all,
Sorry if this may be more of an engineering question, but maybe
someone here has some experience of this.
I am making a toy for my son. There is a small motor which drives a
propeller, which makes part of the toy spin. The motor is mounted on
this spinning part. The power source cannot be mounted on this part.
So I need to make an electrical contact between a spinning part and a
static part. I am not sure how to do this reliably, and with the
minimum of friction.
Any ideas?

I take it, then, that the shaft of the motor is affixed to the rest
of the device while the body of the motor and the propeller are free
to spin.
If that's the case, then you could use slip rings to transfer
electrical power to the motor.
If you could post some photos to a web page somewhere or to
alt.binaries.schematics.electronic of what the device looks like
then we might be able to come up with a physically realizable
solution for you.
