No It is Not!
"Effects of saturation in motors" is the thread subject.
This is determined by the circuit materials used and the magnetic force applied.
Now, it also is a matter of how you want to define "better".
Price-performance (read optimization) or some other criteria?
I said nothing about flux modulation, that is your issue, not mine.
Before departing this thread, I will leave one of many meritorious articles on driver motor improvement where there is nothing to "saturate".

- only a few people here are actually motor designers working in the industry.
- good motor design is no big secret anymore with the tools available today (simulators and measurement systems improved big time in the last decade).
- good motor design today is 90% about being cost-effective.
- good motor design is only a part of good driver design and cannot be looked at in isolation.
For those who might be interested, and can read Norwegian, this topic has evolved to a 12 page thread at hifisentralen.no... Magnetisk modulering i drivere - Side 12
As I am finishing up some drivers for a client, I am implementing a few DC flux stabilizing tricks. It appears that shorting ring inside the magnet also does a fair bit at low frequencies (it is not effective at higher frequencies), so in combination with pole piece flux rings, and high saturation points, they could be drivers with some particular properties. At the same time (since this issue seems to be pretty underestimated) I have simulated the BxL curves under different loads.
