so I have 15 amp viper marine esc


540 motor


Which wire to use to join from motor and esc and how to work out load


Do you solder to motor or use connectors ?


New to this and couldn't find a an answer through search

Assuming an ordinary DC motor. You need to determine the stall current of your motor. This is the maximum current the motor will demand. To do this you need to clamp the motor, in a vice for example, connect it to a battery with an ammeter in the circuit. Run the motor and then using a padded pair of pliers grip the output shaft until the motor stops turning. quickly read the amperage and let go. You can damage the motor if it is kept stalled. The required capacity

of

the wiring can then be determined. It is also advisable to fit a fuse with a value below the stall current.


I solder my wire to my motors. Less likely to come free.

I am into a build with two 540 motors.  Running on 6 VDC, I have 20 amp fuses on each motor/ESC.  Used 16 gauge stranded silicone insulated wire (it's very flexible) You can find tables of amperage vs. wire size online. 



I soldered short wires to each motor, then added Power Pole connectors at a convenient place in the wire run from the ESC's.  On previous boats I have used push connectors at the motor terminals and bullet connectors instead of Power Pole.  Some folks like JR or Tamiya connectors.  Avoid having to disconnect your wires from the motor itself for maintenance.  Those little tabs can break off easily, then it's OH SH.. time.

If the motor is new then it may state on the box what the stall current is or there is sometimes a label on the motor itself.

There are many varieties of 540 motors.  It is only a size
I managed to get 2 very efficient ones for my corvette so it pays to check the specs. if possible.
Others as Derek mentions eat controllers for breakfast. 

[derekwarner]

Yes .....apologies.....need to know the number of turns     or segments [nothing to do with Egyptian turns.......they probably indicate wire looms]

There is always a reason these motors are about 2/6'd each

Ugh. Please dont use Tamiya type connectors. Not only are they cheap and nasty rubbish but they are very inefficient.  If you can solder (not hard) solder wires onto the motor from decent connectors like deans, hxt's or gold pin and tube.

[Peter Fitness]

I'm a big fan of Deans connectors and use them exclusively. I too agree with soldering the wires to the motor, it's a very secure method.

Look at the wire on the ESC.  Use similar.
Soldering is the only secure way to connect to the motor unless it is some type with proprietary connectors.  But all the model motors that I've seen have solder tags.

I to am a fan of deans connectors, but make a adapter for deans to tamiya so you can
Test the esc,s work correctly as cutting manufacturers plugs off to fit your preferred
Connectors will affect your guarantee if you find a fault.

i use XT60 connectors

[Klunk]

deans or xt60. wire i use house wiring. that's rated at 240v 32amp.
