Circular Motion: Going around in circles, and not attached to the center of axis. Like Planets which go in circular orbits (not all)
Rotary motion: Going around in circles, when attached to the axle, or the center of axis. Like the arms of a watch or clock.

It's generally a matter of use. A point can follow a circular path describing a circle. However, all points on a flywheel describe circular paths as it rotates about its axis. Automobiles follow a circular paths on a rotary. The earth rotates on its axis while following a circular path about the sun.

Rotary is rotation around a point (or hub) and involves attachment to that point/hub and centripetal force.
Circular motion is motion in a circle where you do not rotate at a fixed distance or speed. Elliptical orbits can be considered circular motion.
