Old thread I know but to close the loop and since I now have the DVR motor upgrade kit for my 10-325 bandsaw I can say after seeing and mounting the motor that I believe it could be adapted to many 14" bandsaws. You'd need to work out the blade speeds depending on your pulley diameters and most likely your existing pulley will not fit the motor shaft but that shouldn't be hard to overcome.
You can set the controller max RPM of the motor, for the Rikon 10-325 it is 2160 RPM which yields a blade speed of 4000 FPM using the high speed pulley configuration. For two of the very slow pre-programmed speeds you need to jump down to the low speed pulley setup. This motor is more than a 3ph VFD motor, it uses no brushes, no magnets, no rare earth metals. I think you can dial it down to as slow as 60 FPM IIRC. Running the right blade you can cut ferrous and non-ferrous metals, stainless, titanium, and various plastics.
I believe Tecknatool/Straitech have other motor upgrade kits or solutions available, so for those that have expressed interest in use on a DP or lathe or other model bandsaws you might want to contact them. I have nothing to do with Tecknatool or Straitech, but I have had the Nova DVR XP lathe for over 10 years and it's great. My history with the lathe is what convinced me to go forward with the bandsaw motor upgrade once I found out it was made for Rikon by Straitech. If there was enough interest they might even offer a upgrade kit for drill presses with custom programming but that would cut into their NOVA Voyager DP sales so not likely I think.
I'm working on getting it installed and set up on my saw. During the upgrade I found that my drive belt was in poor shape after 10 years so I have a new one (actually two) on order, should be here in a day or two. So dead in the water until I get a belt, old one is too far gone to run the saw safely.
In the mean time I have been installing the guide bearing upgrade kit from Rikon.
