description A cleaning system for a combine harvester includes a sieve for capturing grain, and a magnetic propulsion system configured to move the sieve in a reciprocating motion with respect to a stationary housing of the combine harvester. The magnetic propulsion system includes a magnet that moves as the sieve moves and a plurality of electromagnets arranged along a path of movement of the magnet during a throw stroke and a return stroke of the sieve. During the throw stroke, the plurality of electromagnets may be one of attracted to and repulsed by the magnet. During the return stroke, the plurality of electromagnets may be another of attracted to and repulsed by the magnet. The magnet may move along an arc, and the plurality of magnet may be arranged along an arc adjacent to the magnet.
