Abstract
A random orbit sander having a speed limiter includes a bearing upon which a platen is rotatably mounted. The speed limiter includes a braking member formed of a non-magnetic, electrically conductive material fixed relative to the platen of the sander. The spin limiter also includes at least one magnet supported by a housing of the sander and being disposed adjacent the braking member. A magnetic field formed by the at least one magnet intersects the braking member wherein relative movement between the at least one magnet and the braking member results in the generation of an eddy current force which inhibits rotation of the platen.
