Most drill presses come with induction motor (start capacitor on the outside), a Universal motor is AC/DC very high rpm and has brushes.
When looking at Treadmill motors, they come in all kinds of configurations, depending on what the original manuf. spent on design, I have seen everything from universal motor to various forms of DC, alot of them made very cheaply, so you have to be aware what you are buying.
