Servomotors

Archiver

Hi,
I was wondering if anyone had a site or any information about the
control electronics that are inside a servo. Basically i want to know
how it operates and what circuitry they have used.

Thanks.

Alan -

The only things inside, of any significance, are a feedback potentiometer
and a sevo amplifier. The servo amplifier is a standard feature of any
servo mechanism. This includes DVD, CD, some tape drives, and similiar
applications where precise positioning is an imperative.

I have a datasheet, or can point you to a typical servo amplifier chip, but
use of it will be a bit awkward. The pin-out and packing are NOT what you
might expect to see.

Beyond that, please feel free to contact me off-list for more information,
since the chip can not be used directly from any Stamp product, making this
a rather OT subject.
