Hi!
I am working at a kitchen supply store, and over the years I have collected blender, and hand blender motors, at 1000W and 2000W. Hoping to put them to use some time. I started doing small arduino projects a year ago, but I have no experience in electronics.
So, my question is: After disassembling the blender motors, so that it is only the motor left. How do I control it? Where do I even start?
Can I use some of the hardware already in the blenders?

Thank you!

If those motors are 110VAC (or the line voltage in your area) a Solid State Relay or mechanical relay would be easiest for on-off control.  I don't know how you would obtain speed control.

You need to spend some time identifying the TYPE of motor. Google will lead you to all kinds of sites that tell you how to determine this. Most motors will be of the type where the field coils and the armature windings are in series. These can be speed controlled by using either resistors in series with the motor wires to reduce the motor speed, or by using an electronic speed control to watch the AC voltage sine wave and allow power to the motor for a portion of that sine wave. These motors will all have carbon brushes making contact with the armature.

Your questions do not seem to be about an Arduino use or problem.

These are probably universal motors, designed for mains frequencies, although they may work
at DC as well if the winding inductances aren't integral to the current limiting.

But without some pictures I could be wrong about the type of motor.

Blenders usually have a few different speeds. If you preserved the speed-control unit, that will also supply some clues as to what type of motor it is and how to control it.
