how do you make a voltage splitter to dividea current in two so they act as if they were coming from different sources Answered
hello, i am building and rc tank that uses 4 relays to power 2 motors in both forwards motion and backwards, all running from 1 battery pack. however ive hit a snag in my developements in which the single battery pack was actually bypassing the relays as it connected to the terminals of the motors, therefore not allowing me to use one relay to apply +/- power the motor via the battery and useing another to apply -/+ via another. my only logical solution at the time was to remove 1 of the 3 battery packs being used (were each batpack contains 10X1.2v 3AH AA batteries), and arrange it so that 1 pack powerd the motor when going in reverse, and the other two were to power the motor going forwards, and although this means that my tank would run fine, and the subtraction of 1 pack doesnt make a difference power wise to the motors as they run at max efficiency with 2 packs, its still a real hassle to recharge them as i cant just charge em all up at once, the reverse motor battery pack may run out before the forwards, and vice versa, giving me less time to run the tank, than if they were together.
so now you know my problem, what i need is a solution, how can i make a voltage splitter or current splitter or whatever, so that it can divide a current in two so that if i were to connect a positive wire from current 1, and negative wire from current 2 it would not complete a circuit, and basically act like they come from two totally different sources. this was what i was doing until i realised that when i tested the motors in either direction, it was actually going forwards each time i switched it on, after swaping the wires around when it would just run the motor if the relays werent even turned on. my tank has nothing yet on its motors shafts like gears or nothing, it was a simple mistake.
so please, can anyone help me?
