Hello, this is my first post. I hope it’s in the right place and in the correct format.
I’m currently in the process of building my first electric longboard, although most of the technicalities were taken care of by a friend of mine who built his own board over a year ago. I am mainly using parts from the EU GB run by @ajaynagra. The motor I have is from this GB and its origin is unknown(?). Specs are 190kv 6374 sensored. I’ve configured the VESC via the BLDC tool and all seems to be in order. The problem I have is not an issue of function, but rather the motor is making a weird metallic grinding noise, especially at low RPM. Once it spins sufficiently fast, the grinding stops and it sounds like any other BLDC outrunner motor I’ve heard.
I’ve attached some images of the motor as well as a video with audio.
Any help would be greatly appreciated!
