A compactor includes a plate, a shaft rotatably supported upon the plate, an electric motor configured to cause rotation of the shaft, and an eccentric mass arranged to rotate on the shaft, causing the plate to vibrate in response to rotation of the eccentric mass. The eccentric mass is configured to translate along the shaft.

An eccentric assembly for a compaction machine may include an outer eccentric mass and first and second inner eccentric masses. A length of the outer eccentric mass is in a direction of an axis of rotation of the outer eccentric mass. The first inner eccentric mass is rotatably connected to the outer eccentric mass by a first joint, and the second inner eccentric mass is rotatably connected to the outer eccentric mass by a second joint. Moreover, the first and second inner eccentric masses are separate, and the first and second joints are separate. Related compaction machines are also discussed.
