Default Where to solder the diode

Does it matter where to solder the diode/s? I can think of 3 options:
On the esc
On the cables just before soldering the motor
On the motor

Will we understand any difference in performance? Will it hust the esc, motor, anything?

Thank you

Nick

I have tried it on the motor and also in the wires going to the motor and noticed no difference IMO it doesn't matter if you don't notice a difference just make sure you get it soldered on correctly

I was thinking soldering on the esc. That whay I won't have to worry having diodes on every motor!

I do not know if its true or not. But I read somewhere else in this forum that the shottki diode protects/works better if soldered on the motor itself where the "action" takes place.

This is the ideal place, on the motor. I was wondering if it would create any kind of problem if they was soldered to the esc.

The speedo is where I have mine soldered. If you think about electricity and theory, there is no difference where the diode will be soldered. Electrons travel at the speed of light, so the distance between the speedo and the motor is literally the same place.

Howdy,

as close as possible to the motor is better... on the ESC it won't hurt as long as polarities are right... On V2's you can hardly solder anything (including motor wires!) to the tabs, so a cool trick is to solder it to the motor wires, close to the tabs.

Later,
Paul

This is excatly my problem. Since I have V2 motors it is very hard to solder the motor in the first place imagine how difficult is to solder the diodes!

I thought about the trick to solder them near the motor on the wire but then the diodes won't be still during race and this might be a problem.

I think I will solder them, using extra cables, to the esc!

Lightbulb I guess it depends.....

on the class you race in. I asked basically the same question via email of the makers of my esc (Nosram) and the reply stated that in 540 class you don't even need to bother with it in the first place.

In theory the closer to the motor the better. But Niel was right on the mark. With the short wires we have in our cars it just doesnt matter where it is. Just that its there to do its job. Protecting your expensive electronics.

Ideally on motor pos+ and neg- post.

conveniently on esc motor post, but I wouldn't do this if the motor is less than 23T.

Imagine that the diode has "long legs", so long that it doesn't matter where you soldered it.
Imagine that these "long legs" are the ESC wires, so it doesn't matter where you soldered it.

Novak told me a while ago that it's best if it's within two inches of the motor.
