Abstract
A differential motion conveyor includes a cylindrical moving magnet linear motor to drive a trough into vibration to convey material. The linear motor utilizes a compact, efficient and powerful design using an annular stator which drives an armature. The armature includes opposing shaft ends which are connected to either the trough or to a conveyor base, or to a counterweight depending on the conveyor design, to drive the trough into reciprocation to feed particles along the trough.
