Howdy y'all.
Trying to drive a large inrunner (rotor diameter 320mm, 42 magnets, so 42 poles) with a Flipsky FSESC 4.12. Updated to latest firmware and running in FOC mode.
I was surprised with the level of noise when running in FOC mode, which I'd heard was supposed to be fairly quiet. Running at max RPM at 55V (~900rpm), it's heckin' noisy. I've linked a Youtube video of the noise.
Is this normal noise for FOC or have I done something wrong?
inb4 you're running in brushless DC mdoe - I'm not. I couldn't get it to work in BLDC.
Any help appreciated!
It sounds normal to me. And the motor isn't exactly silent when it's spinning unpowered at the end. Bldc mode is much noisier again.
Thanks for the advice; I'm new to this so it's hard to gauge what's expected and what's malfunctioning.
