You could use a small freq.converter the one's they are using for fanspeed
controlling.
And when you use a 110/230 transformer between the converter and keypunch
you loose a lot of spikes and other distorsion.

Onderwerp: Keypunch that was on eBay
Thanks for whoever it was who posted the info on the IBM 029
keypunch on eBay. I have won it, nobody else bid. After it
has been shipped across the Atlantic I will have to think
about converting it from 60Hz to 50Hz. I have the remains of
a 50Hz verifier which has a 240v / 50Hz motor I should be
able to use. Hopefully the rest runs on DC, so a step down
transformer before the transformers and bridge rectifiers
might be enough. Shipping costs more than the item of course.
Anyone have any thoughts if it is worth trying the whole
thing with just a 240 - 110 transformer? If the motor burns
out, not the end of the world.
