Power Screwdriver Motor
November 29, 2011
So I bought a few power screwdrivers for the main drive motors for my new robot project. I have started creating a rocker bogie suspension system out of PVC pipe. This suspension will require 6 drive motors. The power screwdrivers run on 4 AA batteries. So the motors are 6 volt. By browsing the interwebs I figured out that one AA battery supplies about 2.4A. So I figured that each motor would require 9.6A. But since I have 6 motors I would need 57.6A. This would require a huge SLA which would weigh about 20lbs and cost around $100. This is simply unrealistic for my project (the weight, I would be able to pay for it somehow). So my question is do these numbers for the current draw of the motors seem accurate? If so, are there any alternatives to a 20lbs SLA? Sorry for the long question and thanks for your help in advance.
