I am a new guy , I just get a HW4.0 based board and try to test it .
what I found is that speed is different using FOC mode and BLDC mode .
BLDC motor : 400KV, Power:25V. MAX no-load speed should be 10000rpm @25V. (400 * 25 = 10000 rpm)
In BLDC mode I got 9300rpm( it's not bad), but in FOC mode it just ony 8500 rpm,too slow ...
I think two modes(FOC,BLDC) could be different a little bit. But 9300rpm : 8500rpm ,it's too slow to use FOC mode .
I tried to adjust "FLUX_LINKAGE" value to smaller value , but the speed is not speed up enough . if this value too small ,motor run failed .
What I supposed to do to get speed as same as possible between BLDC and FOC mode ?
