Radar drive motor
« on: April 29, 2006, 03:36:11 AM »
Does anyone know of a really small motor suitable for a radar drive?

Ideally I'd like something no longer than 1/2" - But is there something that small available?

Try the motor from a used hard drive they are 12  volt and some have gears that you can adapt.

As uusual, I put my hands in gear before my brain.  I meant to say CD disc drive . The motor that drives the tray is quite small and  at six volts, it is almost perfect speed.

Thanks guys - That gives me a few places worth trying, I wish I'd thought about a CD drive motor myself as I threw out two old CD Roms about 3 weeks ago!

I don't think I'll strip down my computer to rob one from it :-)

I know the query was some time ago but ......
Why not try my modification to an SD200 Mini Servo .
Not difficult and works a treat.

I have attached the PDF, but if you want to, look at www.edinburghmodelboatclub.org under the Help Pages

Laptop CD/DVD drive, system tray release function, is very often handled by a motor of a size similar to those used at the popular toy helicopter tail rotor. Much smaller than the one moving the tray on a desktop unit - I haven't seen a failing motor after recovering more than 10 units.

hi , i  know this is a realy old topic but nevertheless here"s my idea of a good way of finding motors that small
the motor that is used for the vibrating function in a cell phone are just what you need
best (altough late  :laugh: ) greetings from bombus
if i haven't done it i'll try it
and maybe it will work
