How many motors?

[silo_xtreme]

Hi everyone.

Just a simple question.  Do you find it more economical to use 2 motors or 4 motors when attempting to reach a certain torque limit?

I'm defining economical as:  less money, less weight, less current usage, more torque.

hey guys, i'm new at this but with my limited experience i think that 2 motors is better. mostly because it does cost less and to make up for the lost torque use a caster wheel for the front. Also try modified servos, they help alot too, but thats off topic,try using small wheels too, that means less weight and more torque.

It entirely depends on the motors you can find, the prices they are sold for, and your required torque/rpm/size constraints.

Basically, to answer your question, you need to design both systems then ask which is better to build.
