Rotatory motion:

            The spinning motion of a body about its axis is called its rotatory motion.

Examples:

The top spins about its axis passing through it and thus it possesses rotatory motion. An axis is a line around which a body rotates. In a circular motion, the point about which body moves about which a body goes around is outside the body. In rotatory motion, the line, around which a body moves about, is passing through the body itself.

The motion of a wheel about its axis and that of a steering wheel are examples of rotatory motion. The motion of the Earth around the Sun is circular and not the spinning motion. However, the motion of Earth about its geographic axis that causes day and night is rotatory.
