I guess the "dual" response would be, how much efficiency gain are we talking about, and is it only at full throttle, vs cost/complications, ya know. Is it good enough to get started with, kinda sounds like it will handle 48 volts 300+ amps no problem. Throw some pwm at it and monitor the current I recon.

Also the synch gains are probably frequency dependent.
