hobby motor control
October 25, 2008
Hi guys, I am looking into getting a small electronic speed controller from the rc hobby store to run a couple of small dc motors (tamiya dual gearbox), does anybody know if these take the same pwm input as running a servo or does the r/c gear use something else? I thought r/c gear used pwm but when browsing online for motor controllers some say pwm, and some say r/c (in addition to analog or serial or whatever else). Is there a difference? Also, some use a battery elimination circuit, which means the reciever unit (which is sending the signal to the esc) will draw power out of the esc through the same cable, "eliminating" the need for two batteries. this sounds like bad juju for the electronics I am planning on controlling it with (basic stamp... shut-up ;). does anybody know more about these hobby controllers?
