Micro 90Rpm Motor Hign Torque

Skip to comments   Jump to end

Looking at making a 1:2 scale r2d2(not in crazy detail) from wood and just for reference I was wondering if anyone had seen a pretty small motor with high speed and if possible, a mount? The wheels I'm looking into are 3" diameter by 0.2" wide but I could change quick. Needs to be under 4" as the feet cover is only 7" at the bottom and 3" at the top. A servo style motor would fit best but don't see any 90rpm high torque servos. Any suggestions?

You're on the right track... 12V gear motors will give you the power you need... I have bought some from eBay... Robotshop.ca is an awesome place for robot supplies too...:D

Just rechecked the specs on the last link troy posted. HOLY COW! 44.8Pounds/cm!?! I find it hard to believe but even if its half that it would work.

Yep, most of my robot chassis use motors with 6mm shafts... Robotshop.ca has wheels that will fit those motors... Lynxmotion uses them for their 37mm gearhead motors too...

Could you give me a link? only could find one on servocity. Might save some $ if what your talking about is cheaper. All about the cost!

Thanks, Tech

The one I listed (20kg/cm) converts to approx 278 oz/inch or 17.3584 lb-in. So I guess it might be.
