Title: Advice on dc Motors
Post by: ionyboy on March 06, 2012, 03:51:33 PM
Hi guys.
I would appreciate if you can give me some advice on what dc motors i can for the sumo bot i am building.
My robot is 15x15 cm, mass is a little less than 1kg and it is powered by four  1.5v  batteries.I bought 2 motors http://radionics.rs-online.com/web/p/dc-geared-motors/4130600/ (http://radionics.rs-online.com/web/p/dc-geared-motors/4130600/) but they are very slow i.e rpm. Can you please give me some advice on what motors should i get in order to get good torque to push other bots away and also a good speed.

Hi,

[...] mass is a little less than 1kg
How little less?

What do you define as good torque?
What do you define as good speed?

What 1.2V batteries (cells) are you using? AAA, AA, C, D or what?
Are they rechargeable?

Do you have a motor controller for it?
If so, what is the specs on that?
