I think that would work fine but it is not needed for what you’re doing. You really only need the two ends of that on one wire. (the two female port connector things. names are hard) and then follow what @b264 said to do with it. You could still use that one with the extra noise isolation but I don’t think noise should be a problem anyway.
Although I have no idea how many pins are needed when tying two vesc’s together so if that thing doesn’t connect to enough pins then it won’t work.
As others have mentioned about the CAN Bus, it might sound weird but I’m actually trying to avoid using it on the setup I have, the setup I had before used two motors with built in ESC’s and I would take the signal and ground from each one. Here’s link to what I was using before:
Yeah, that’s why you have multiple options. No problem to not use CANBUS.
Are both ESCs connected to the same BAT- (black) wire? If the grounds are the same then make sure you set up the software on the VESC, it needs extensive setup in software before it will run. You need to set the battery voltage cutoffs and run motor detection, and then set up the application for PWM (erroneously called “PPM” in VESC) control before it will spin the motor.
If it still doesn’t work, describe exactly what you’ve done here (with screenshots) so someone can attempt to assist.
To make sure that nothing was funky going on before doing this, I made sure that each motor and esc works separately when using the RC controller and ran motor detection, setup cutoffs etc.
After that I made a Y-Harness coming from the RX. One ESC gets signal, power and gnd and the other gets signal. (I did attempt with the second one having signal and gnd as this replicated the setup I had before).
Both attempts did not let me use the controller setup option, essentially as soon as I plug in the 2nd ESC into the harness the first esc and motor stop working
Update: Got it to work, had an old 4.12 VESC from 2017 lying around.
For those who find this post again, or those curious.
To have two vesc’s wired up to one PPM/PWM receiver, connect the +, -, and signal from one ESC into the y harness. For the second ESC only connect the -, and signal, however for the signal put a 2K resistor in series.
