I have a 110v 1/2 hp motor that came off an old craftsman bandsaw and I want to use it to drive a diy sharpening system like the one in ShopNotes vol. 18 issue 107 here. The designer intends for the sharpening system to be driven by a drill press, but I want to modify the design slightly so that it has its own motor.
My problem is my bandsaw motor turns at 1750 rpms and I want to slow it down to about 480 rpm. It has been 30 years since I took electric motors in school and I don’t know (1) can my bandsaw motor speed be controlled without damage to the motor, and (2) if it can, what kind of speed controller do I need. I.e. Do I need to vary the voltage, current or both?
Can anyone point me somewhere online where I can get a basic overview of a/c motor control?
Thanks for your comments!
