Changing motor for exactly same motor, esc setup needed ?

Hi all, probably a dumb question; when changing one of the 2 motors and it’s the exact same one (brand/make) , do i still have to set it up in the ESC ?? Or just try and see if it goes ?

One of the motors has the axle coming loose, John from BoarsofSweden send me a new motor a while back with setup-instructions on Freesk8 app , but that app is no longer available…

Was thinking (hoping🤪 ) simple logic that maybe because the motor is exactly the same, that the esc setup would be abundant…(?)

I DID buy the Vesc Tool app for my Iphone today, but i rather stay away from these gadget thingies😉

Help plz :call_me_hand:t2:

It is definitely good practice to re-do motor detection as the motors will never be exactly the same. At the same time I had a VESC blow up during motor detection last week so I’m going to avoid doing that more than necessary in future.

But generally you should do motor detection it will help with momentary current spikes.

When i do the motor detection; first i save the default settings , yeah ? Because these “default settings” are what was on the board to start with ? Or am i wrong here, default meaning that it will bring it back to “factory settings”…?

I’m watching the video on youtube by Jeff (designer of the Vesc-tool app) but he kind of skips that part…:grimacing:

I need the settings that are on the board right now to be used in the new calibration… Not sure how.

The Unity app was “simpler” to use i think. For changing the motors on my Flux Motion board a good while ago ; I did the setting up with the help of Frederique, may he rest in peace, and it worked out fine.

I usually don’t save my settings when doing detection since I’d only need to change motor current, voltage and fault time. It’s not hard to do, Mboard/Shuttershock has a bunch of good videos that will show you what to do. Also after doing motor detection you don’t have to adjust anything with the app/remote settings.

I’m pretty sure this is a spintend thing only

should the motor detection be done with the wheels and belts or without the belts?

Would definitely recommend running hall sensor detection. All sensors are slightly different and sensor boards are glued manually with few degrees of variation.

Thanks all ! I went and done it this evening. Got it running. First I tried seeing if it goes without the ESC setup ; just smacked the new motor on. But nahh it did’nt go. It did’nt “recognise” the new motor i guess. One was spinning , the new one just glitched a bit. Had to do the setup.

John from Boards of Sweden put some tutorials on Youtube so i could find the data needed for the setup. The difference in use of the Freesk8 app compared to the Vesc-Tool app kind of scared me, but after comparing all the data it was do-able.

I did it without, works fine.

You definitely want to redo motor detection when replacing a motor even with an identical one off the shelf. This is because no two motors are the same.

Personally no idea. Some people said it’s best to do it without so the motor can free spin without resistance. I run gear drive and I run detection with the gears engage and never have any issues. :man_shrugging:

Spoke too soon :rofl:

That’s some bad luck

Maybe this a thing that happens or needs to be figured out.
