    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.
