I have some nema 23 stepper motors, and I'd very much like to replace the shafts. However, removing the rotor from the housing demagnetizes and damages them. These motors are assembled, and magnitized in place. The rotors are 2 pole axially magnetized, doesn't seem like a big deal.
Here's a link with a nice picture of what I'm talking about.

Again, doesn't seem like that big of a deal. So then, there's this demonstration of remagnetizing a servo motor, which also needs to be magnetized in place. I note that the power supply is as big as a closet, and the real look of fear on the tech's face when he flips the switch. Skip ahead to 1:30 for the hiding behind the corner and look of serious concern.

I'm thinking the large power supply is for remagnetizing larger motors, it wouldn't need to be that large for something like a nema 23 stepper. Does anyone know how I could find out how many wraps I would need for a magnetizing coil, and needed voltage and amps? I have access to a 180a welder, so getting enough current shouldn't be a problem. I can also print plastic spacers to hold the motor exactly in the center of the coil if needed.
Thanks!
