Powering motors

Other Hardware General Electronics

My arduino is yet to arrive, but I want to get things in place before it does. I have 4 brushless motors each requiring upto 18A. I have a battery that can supply the motors. Can someone advise how the circuit should be to supply the motors and and the arduino from the battery?

I assume the motors and arduino should be isolated from each other in some way, but what is the recommended approach? I guess this is a fairly standard thing to want to do, so is there a circuit diagram somewhere that might help?

Thanks,

Here is some reading to get you started:

Alas that could mean several things. Which motors exactly? Datasheet or other
detailed description is needed. Perhaps they are RC brushless sensorless motors
(in which case you need 4 ESCs to match) perhaps not?

I have ordered ESCs to go with them, the motors are specced below. I'll read through the links provided, but just thought this was a fairly common thing to do.

Thanks,
