Hello Mates,

I m making my project on Wireless robotic arm using microcontroller. I need DC Geared Motor with following specifications:

1) low RPM.
2) High Starting torque.
3) High Holding torque.

Can any1 please help me in selecting motor ??

Sounds to me like you need a worm drive on a standard small DC motor. Worm drives 'gear down' dramatically and are not too efficient so the holding torque is very good (due to the friction). A small motor needs to rev high, so a >=10:1 reduction would be quite handy. I should think.

look for hobbyist sites that's where the creativity is.

here's one of my favorites

and search on terms like 'robotic supplies'

mpja is in North Florida.
surely there's somebody similar in your part of the world..
