Motor BLDC Revolt RV-120Es 12N14P
Kelly Controller KLS8430H
Connected in a 80V battery

The motor starts locking at 416 RPMs (as shown in the video). We suspect about an error in the following parameters: IQ Kp; IQ Ki; ID Kp; ID Ki. We don't know which are the values to put in these parameters.

We already made all combinations of phases in the inverter, but we still get the same error. Always making the ''identification angle''.

When we turn on the motor at 48 V, we don't have any problems until we reach the max RPM.


Here's a video Showing the motor locking at 416 RPM: https://www.youtube.com/watch?v=Pur-Ppc82o8&feature=youtu.be

Did you do the Angle identification? Set the value to 170 in the 'Identification Angle' field and restart the Controller.
After it has finished the procedure restart the Controller once more.
