Hello folks, this will be my first time writing in. I have acquired a 1981 doall band saw. The head transformer on the unit has a wiring diagram showing 480 to 240 3phase. My intent is to convert the unit from its current 480 wiring structure to 240
volts. Just to give you some info on the saw, it is mostly original as far as I can see. The motor is a 3 horse power dc motor. It also has a smaller unit for lubrication. My issue is that I have rewired the unit to the best of my knowledge for 240
3phase and the unit does start, however it does not run in full capacity, approximately 30 seconds goes by and seems to bog down, at this point I shut the unit down with fear of damaging the dc circuit board. If anyone here is familiar with this saw or
with rewiring such a unit, please shed some light on the situation for me. I will take and provide pictures of the unit Thank you very much, Tesla
