it really depends on your needs. you really want to consider HP, voltage, Amperage, and RPM. many motors can be used in the shop for many things from shop made machines, to replacement motors to existing machines etc. but you have to match the motor to the application it’s set to do. AC motors are easier to deal with than DC motors as they don’t require an additional controller/driver, but DC motors can give you variable speeds and reverse operation with ease as long as you have a proper driver for it.

treadmill motors are a good case of DC motors that can be used for variable speed applications (replacing your Drill press motor for example and getting rid of changing belts). any AC motor that runs at 1750 RPM or lower can be used for a honing/sharpening station hp can be as low as 1/3hp or even less.

it really depends. but I’d save good functional motors at least long enough for me to figure out if I can utilize them for anything.

(am actually in the process of replacing an AC motor on a lathe with a DC motor for variable speed without having to deal with belts):
