Anyways...
I have never used Flux weakening so I know little about it. I always just overvolt motors

Of course, I respect that. Sorry for asking.
Do you mean me?
Just send QS sales a question, adress is carrie@tzquanshun.com or judy@tzquanshun.comI'm having trouble finding the Votol 200 for sale anywhere
By educated guess:3.4.4 Attention
...
3.4.4.5 Weak magnetic failure: The flux weakening value exceeds the motor and controller parameter values, causing the motor to demagnetize and the controller to burn MOS.
could you share the calcs for this?larsb wrote: ↑Nov 14 2019 3:54pmWhy not just google the field strength and conditions needed to demagnetize a neodym magnet. I bet it would take less time than writing the speculations.
Apart from that i'm with danGT86.
I calculated the extra torque that this motor could give in field weakening because of the reluctance in IPM design, it was very small. I consider it as a normal bldc in this regard.
Is this the one you mean?minde28383 wrote: ↑Nov 12 2019 2:37pmAll stuff is related. Have you heard holistick. It's not that but similar.
Google'ing the coercivity of Nd Magnets yields somewhere between 600 and 1200 kA/m.
Whats our field?
But as i've got it, reluctance torque and field weakening are different concepts?
