LRP ESC with TRANSPEED BL motor ESC/Motor Turns

[Supa Ryda 90]

hi guys, trying to make ma df-03ms more faster in a usable way, i bought a (LRP) Tamiya TRANSPEED 9.5T motor brushless of course, and after i bought a LRP FLOW competition whom has this sign >9.5T, so it was correct but unfortunately, having bought it on ebay after three months the warranty was it's expired, and when i finally fixed it on my df-03ms after a lot of work on another car, i found that it wasn't working. After a lot of tests, still not working, i decided to buy the LRP FLOW worksteam who has the sign >3.0T. Foolishly i forgotten to tell that i have a 9.5t bl motor, now i suppose that this ESC doesn't work with my motor, it's correct ?? What does it means >9.5T >3.0T?? So Now I have to buy a new motor to run the Flow Worksteam and a new esc to run the 9.5T motor ? Do you have any advice for me ? thanks guys.

>9.5t means it will work with any more with more than 9.5 turns.... So it may not be suitable for your needs.

ok, but i have the esc doing >3.5T and my motor it's a 9.5t so my esc will not work with my motor right ?

Usually, the ESC specs states a minimum turns limit that shouldn't be under-run by your motor. If the motor's turns are lower than the ESC limit, the ESC is likely to switch off into thermal protection mode.

So, if your ESC has a limit of 3.5 turns, and your motor has 9.5 turns, you should be safe.

So, it would be no problems using this combination right ?

Yes.

The other way around would be problematic (e.g. ESC turns limit 9.5 with a 3.5 turns motor).

LRP make high end products.

While your Flow Competition is recommended for motors >9.5T, it should work with a 9.5T, at least for a while. In a stressful situation it might overheat and cut out temporarily or potentially even die, but out of the box it should work.

If I were you I would contact LRP directly with your problem. They might want to help you, warranty or not.

Or maybe we can help? Post pictures of your setup with all connections and what steps you've gone through. Setting up ESCs can be frustrating work.

Your LRP Flow WorksTeam ESC will work very well with your motor.

Turns explained very quickly:

The number of turns in a motor denotes how many times the wire is wound around the armature. The thicker the wire, the fewer times it fits around the armature and the more power can go through the wire. That is why a low number means a powerful and power hungry motor.

okk, thanks a lot guys, now i see better, more clear.. thanks

Stupid question regarding your first LRP ESC not working..

You are using a sensor cable between the ESC and Motor aren't you??

Many of the early LRP brushless ESC's will NOT work without a sensor cable connected.. Not sure about the Flow, but its worth mentioning..

ALSO.. Make sure that the A,B, and C on the ESC motor wires align with the A,B and C on the motor.... That is wire A from the ESC needs to go to terminal A on the motor, B to B and C to C...

And the flow series are *extremely* finicky when it comes to the sensor cable being seated, especially at the ESC end.

I use tweezers to really push the cable in and make sure it is seated on mine. Bit of a design flaw actually, and especially annoying as it is so hard to access typically.

Definitely check this 100% before giving up!
