It depends on the motor and wheel that you want to match up, and what the purpose of the wheel is.

For example, in some cases you could press the wheel onto the axle of the motor. You could use a hub to do the same thing. But, in those cases you want the wheel to spin as fast as the motor does, and for the vast majority of motor/wheel setups that isn't the case. So, you'll need some sort of gear reduction. That could be a chain or belt setup with different sizes of sprockets or pulleys, respectively, or it could be a gearbox.


The big trick is that it's entirely dependent on the motor, the wheel, and the application. What works well for, say, a shooter wheel might not work so great if you're trying to use it in a drivetrain (read: might not work at all).
