Abstract
A drive mechanism for an animated display includes a plurality of planetary gears supported on a rotatable planetary gear support. Each planetary gear meshes with a stationary sun gear and is affixed to a multi-finger magnet support. Rotation of the planetary gear support causes the magnet support to revolve about the sun gear and also to rotate about its own central axis. One magnet from a first set of magnets is supported in each finger of the magnet support and travels in a first orbit about the rotational axis of its respective magnet support and in a second orbit around the sun gear. The rotatable planetary gear support can also support a second set of magnets for orbital movement about the sun gear. An optional auxiliary magnet support rotates about a center axis of the sun gear and supports a third set of magnets for orbital movement.
