For my project, I have a winch motor that takes 12V. I have a 12V battery to power it. I want to be able to set up a remote control system consisting of a receiver, transmitter, and one of those brushed motor speed controllers (ESC). For example, this ESC can be found on HobbyKing.
However, I am confused about the voltage ratings on the ESCs. For the input voltage, it can take up to 3S Lipo, which would be about 4.2 x 3 = 12.6V. That would work with my Lipo battery. But I am confused about the output voltage. There isn't anything written about it.
Do we assume that the output voltage to the motor is the same as the input voltage to the ESC? In my case, that would be 12V. Or will these brushed ESCs drive the motor at a lower voltage?
