Hi,

Anyone know where I can get a small 12v Stepper Motor 4-phase, unipolar, 1.8 Degree, medium torque, for my focuser. It does not need to be a large one!

Hi,

I really need a 12v one to make the thing as simple as possible, but thanks for the offer.

I might have one. I'll have a look through my stuff and get back to you.

bear in mind that the motor voltage rating is for continuous use. You'll probably find a 5v motor will work just fine for a focuser at 12v.

I'm sure Mel Bartels had something to say about that on his project pages.
