Re: Stepper Motors

Above is a study by the Army Research Laboratory comparing brushed to brushless motors for use in UAV's and land robotics systems. I like it because it talks about commercially available motors and practical concerns such as the fact that for consumer brushless motors the specs an engineer would need like stall torque, free speed, stall current, etc, etc. (what we are used to seeing for dc permanent magnet motors) are rarely if ever provided.
