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?

Yes, there are some small Swiss geared motors in some of the shows, they rotate at 60 rpm on 3 volts.
They are about an inch long and about a third of an inch diameter.
Also doesnt Alistaire at  model Motors Direct have some motors suitable for radars?

Hi Eddy,
   I use a solar motor drive unit  (item code no 570-454) from squires in Bognor, its the best ?3.95 ive spent in a long time.
especially as the same product from other traders will set you back a tenner, just because they call it a radar motor.

You could always strip out the motor from an old servo. I suggest that you keep the original servo gearbox and cut off the small tab that prevents full rotation of the arm.

I appreciate the replies guys, thanks.

But a servo motor is too big, as is a Buehler motor or anything that Alistair lists at Model Motors Direct :-(

What are the dimensions on the solar motor you mentioned Jumpin Jack?

Sorry, but I'm really stuck for space to fit this, hence my original message stated 1/2" maximum length - Diameter isn't such a problem, I could probly get away with 1.5" dia, but length is critical...

Eddy

i have found these small ones, Faulhaber Micro-Motor:

15 ? x 12 mm
 3 Volt / 324:1 / 32 Upm

But the price is hot: 44,00 EUR

I recently bought a micro serv for under ?7.00.  Removing the electronics and the stop tab on the output gear should give a small, light motor and gearbox capable of rotating a radar at a reasonable speed.  Or, if you can use a spare channel to control it, just disable the drive to the position sensing pot when you take the stop off the output gear.

Only just read this but if you're srill stuck you could try

Not done any business with them, just saw the site.

 i use a tiny electric motor and gearbox that i took out of a LEGO kit,  its red in colour and  15mm x 15mmx 15mm - basically a cube......sadly i dont have any more, but worth a look on say ebay....its happy operating on anything from 3.6volt to  12 volt- the gear ratio is so low geared the increased voltage does not seem increase the output speed  !

Hello,
In a Mobile Phone, that vibrates to let you know a message has arrived, is the smallest motor I have ever seen!!.
About 1/4 inch dia, less than 1/2 inch long.
The motor shaft had a offset weight on it to make the unit shake while running.
They were on sale at a Computer Fair, but dont know which one !.
Check out the phone folk!.

Action Electronics do  aneat motor and gearbox for about a tenner. It will run off 6v 0r 12v depending which resistor is fitted, full instructions included.
