Hub motor e-bike not recognized

Hello everyone,

I have an e-bike whose controller is broken so I am thinking to replace it with a VESC 6 I have. The problem is I cannot get it pass detection. In BLDC auto detection it stutters, then beep and I get a detection failed error. The motor is an ABB 3-permanent magnet AC synchronous motor, wired in star configuration. I connected the neutral to the - of the battery. Its nominal power is 250W.

What can I do to make it pass detection ? I tried increasing duty cycle and current, it didn't worked.

Thanks in advance !

Olivier

The neutral of the motor should not be connected anywhere. Connecting it will definitely cause problems.

Thank you so much, I've tested it and it worked ! I was a bit confused by the ground and neutral definition, but it works ! Thanks again !
