Hi,
recently purchased a mill for home shop. Origional motor is 575v 3 phase.
I knew right from the start I would need to do something special to make it work. But based on the options, what do you recommend????
First off shop is home based, has 220v single phase.
So as far as I have researched options are........
1) a transformer to go from 220 to 575, and a phase convertor.....
2) replace the motor with a 220v 3 phase and then use a phase converter ie a VFD for speed control
3) replace the motor with a 220v single phase motor....
4) replace the motor with a DC motor and a DC motor drive with speed controller.
Some factors to consider, the mill is not a variable speed head, so changing speeds requires changing belt location on the pulleys, easy enough but a minor pain just the same. So the idea of some type of electronic speed control would be nice.
From what I have been told, speed control would be difficult or not possible with the single phase motor option #3.
Also the origional motor is a short fairly large diameter motor, and was told because of its design, a good torque motor. As torque is what is wanted for a mill, if switching to the more commor taller narrow motor, an increase in HP selection may be suggested for best applications and production of torque.
Any suggestions would be greatly appreciated,
thanks,
Ken J
