Uh, some motor controls questions...

What per-unit impedance are you targeting for the stator winding?

Does the motor controller need an LC output filter to keep the motor's high-frequency current reasonable (thus forming an LCL with the stator winding), or is the stator winding inductance sufficient on its own?

What techniques did you employ to get a wide speed range? Is it an interior permanent magnet machine, surface-mount permanent magnet machine, etc...

Does the controller have a common-mode filter of any sort to cut down on the common-mode bearing current?

Are you building off of 1200V SiC 'FETs or 1700V?
