Schottky diode

[lee.romang]

Do you still need to run a Schottky diode with the new orion revolution motors?

[MattW]

yes.

..and you get top marks for spelling it right!!! ;D

Careful where you put it. The soft copper brush holders are easier to bend than the old steel hoods and tags. If the Schottky got hit in an accident, it may bend the brush holders and cause damage you can't easily repair.

I've seen one attached using a couple of extensions made out of motor/battery wire - if the Schottky gets a clout it merely bends out of the way. HTH :)

schottky diodes should really be ran on all motors. as you may know the diode stops voltage spikes.

power from the esc is being pushed into the motor and under breaking the motor is essentially slowing down or reversing which turns the motor into a generator sending electricity back to the speedo. all esc's are protected against this with internal fets which dissipate the electricity safely. a diode will just help to keep the esc even safer

Could just put the diode on the motor wires to keep it well away from gettin hit

[Chris Bamber]

yeah thats a possibility

I've seen them mounted on speedo's like the LRP & Nosram, across the solder points on the speedo itself. That way they're well out of harms way, and you only ever need one per car not per motor (Same applies if you place them in the motor wires)

[Chris Bamber]

could that not be a power cap. dont mean to insult your intelligence

[_Sleigh_]

Fair comment, but no it was both. :P

[PDW]

Also be aware that the Schottky-on-the-speedo solution can turn the motor wires into a couple of aerials for the high voltage spikes. I have had problems with this in the past - all cured by putting the Schottky back on the motor. HTH :)

I always thought that if you needed to fit a schottky ie your speedo requires you to then, it should be fitted as close to the motor as possible.
