HectorThis is a concept that cries out to exploit Metglas laminates, does it not?Hitachi now owns it, and sells this lovely stuff in a variety of ways, including by the roll, last time I checked.You un-roll and snip, forming it (Wearing gloves)
as it is thin, and sharp.I bet double sided acrylic adhesive might just work between laminations to shape it to your every whimsy. Take a Dremel to finesse the ends to fit the magnetic rotor.This might be a low tech interesting experiment, once the fan motor is cobbled together and shows promise, first to test the concept.Cheers Warren

lenz intrusion is proportional to the bad quality of laminates and losses , that is why RV is essential in R&D as you can determine with reverse dynamo-meter even the loss caused by the touch of a feather ... and true this little demon can be tested using a modified cheap shadow fan motor using a laminate rotor free of shorted turns with 2 side cuff off to make it a magnetic switch . the shorts in the core "shadow" are eliminated as are not required
...
not so hard to test the concept discarded microwave ovens are a source of this type of fan usually have space in the coil to add the dc exciter coil to it .
winding values are respective to core specifics and if series or parallel exited i gave the parallel circuit as is simpler to understand . if inoperative just reverse one coil polarity , the speed of rotation
of the interrupter has a sweet point under a given load and voltages generated at which is more efficient .
