Gearmotors compared -- current draw
Side-by-side comparisons



Traditionally, BEAMers have used motor current as a simple measure of motor efficiency (obviously, lower is better). Let's see how the motors compare over the range of voltages normally used (0 - 5 V) in BEAMbots:

Things are obviously pretty crowded below 100 mA; let's zoom a bit closer on the data in this realm:
