aeronaut Pilot boat

Hi

Im currently building a aeronaut pilot boat , twin motors can i control them with 1 esc or 2 esc's .

Thanks

esc

Andy. You can certainly use one esc, just wire the motors in parallel.

What motors are you using? The caveat for one esc is that you do not use high powered motors, or you run into esc cooling problems.

Using two esc does mean you could have differential control over the motors to give better manoeuvrability but I shouldn’t think that’s an issue with something like the pilot boat.

Hi ashley

I have pair of mtronics 400 motors , if using 1 esc the motors would spin same way ? As i need 1 left 1 right ?

Thankyou

Hi Andy,

The normal practice is to have handed propellers ie: 1 lefthanded & 1 righthanded.to counter act the torque.

Just swap the wires from the esc to one of the motors over. One motor will then spin clockwise, and the other anticlockwise.

The key thing about using those little 400 motors is to keep the current draw below 10A each. If you're intent on using just one ESC then make sure it will handle 20A continuously – which means ignoring those Chinese-made ones which claim 320A!

Motor current draw is governed not only by the battery voltage, but also by the load from the propeller. The simplest way to check this is by using a test tank and measuring under a realistic load. Connect the motors direct to the battery with a meter in circuit, read the current.

If a meter is not available, a bag of assorted fuses and a fuse holder can be got from most car accessory shops for a little less than a cheap meter from the internet. Just try the various values of fuse starting with the lowest until you get one that doesn't blow. Next value up from that is the ESC rating needed. Two motors, twice the current, probably a higher rated ESC.

Most DC motors work the same rotating both ways. They usually have a red dot by one terminal. If the dots are connected to the same wire from the ESC (say, the blue one), both motors will turn the same way. If one motors red dot terminal is connected to blue, the other to yellow, they will spin in opposite directions for any movement of the ccontrol. Any differences will be down to manufacturing tolerances and different levels of drag introduced in the two drive lines.
