So This a follow on discussion as seen here https://endless-sphere.com/forums/viewtopic.php?f=31&t=75494&start=275
im personally interested as im considering 2 inrunner motors one spm kv of 68 and a qs ipm kv 41 ,my main question is is fw worth the hassle .
As LFP has quoted ipm's with large stator iron can achieve only 2/6% hit on efficiency, and if this is the case then the low 41 kv ipm could work for me and sounds awesome. There is also a bonus reluctance torque advantage that ipm's can produce but is this a free lunch?? as you have to tune this in and im sure it would need extra amps ? but again if this is inclusive of the 2/6% then im excited.
