    Default 20 kg/cm dc motor

    hi guyz

    What is your budget , The above motor is a 20 kgcm i think stall torque shich is not adequate for robo wars ( if thats ur plan ).

    Look into very high torque motors ( if you wish to win ) and appropriate circuitry.

    Post more details on what you wish to build in details and ur budget.

    I want high torque motors for the bicycle chain tracks (homemade) and along with that am making a fire fighting robot so there will be 2 bottles filled with water,1 ltr each,on the robot

    and does the motor i discussed about above really gives 20kg/cm torque ?
    and one more thing i never understood what does stall torque represents .so can you tell me what does stall torque means ?..

    And the ROBOTMARKETPLACE is not an indian store so shipping charges would be quite high.(had a bad experience importing parts from foreign countries)

    Bicycle chain tracks will have no traction when used, if you are planning for fun /college projects they are fine ( though ill never recommend them ) , wanna save some money... look into car timing belts.

    Thats what the site owner has written ... 20kgcm

    Look into this motor too

    http://www.nex-robotics.com/products...der-motor.html

    Stall torque is basically when the motor barely moves , and its not recommend usage , take 25 % less of this as safe operating range.

    I recommend importing if you wish to win something by bashing the other component out . Stuff available in India is not really high performance.

    No , you do not requires diodes with L293 , It has inbuilt diodes.

    Can anyone please tell me what is the required equation for calculating the value of capacitor to be applied accross the motor of 12V ?
    I've read when we reverse the polarity across motors, huge voltage spike occurs. what to do ?
