M8325s 100KV UNBALANCED_PHASES

Hello,
I have four M8325 100KV motors, but one of them doesn’t calibrate properly.
When I force the calibration, it completes successfully—the motor makes the sound and moves—but if I don’t intervene, it won’t calibrate.
The motor works occasionally, but only about 1 time out of 10.
I’ve already checked the phase connections.

Sorry to hear that! Do you have a power supply with constant current mode you can use for a test?

Also, did you cut or strip the motor wires in any way?

Hi, yes i do have a powersupply with constant current.
All wires look great and are well connected to S1 controller.

I have other 3 motors and S1 combos and they all work without any issue.

I was wondering if the issue could be encoder related?

Hello,

I have changed the S1 controller to another motor that was working before, i started a calibration and same issue again (unballanced phases). I also tried another S1 controller on the old motor and it was also working without any issue.

So it seems that the controller is the problem.

Hmm, can you please post a picture of the top and bottom of the ODrive?

Can you show what the ends of the motor wires look like?

Hello, should we send back the controllers as they are brand new?

Hi! Apologies, yes let’s do an RMA for this. Can you please reach out to info@odriverobotics.com?

Sure ofc, thank you very much four your time !
