The DC (or "direct current") motor rotates a small shaft you can attach anything to. Try attaching a wheel! Use it to spin, turn, twist, and roll.
Note that this bit is NOT compatible with the following items - Droid Inventor Kit - Space Rover Inventor Kit - Cross axle mechanical arm (not available separately) - Cross axle motorMate (not available separately)
For a replacement DC motor bit for the kits and accessories above, see the cross axle DC motor.
