A compactor includes a plate and an electric motor coupled to the plate and configured to impart vibration thereto. The electric motor including a stator and a rotor defining a rotational axis and having a center of mass that is not intersected by the rotational axis.

The present invention relates to a method of controlling operation of a vibratory roller (1) comprising a roller drum (3) and a vibratory mechanism (2) having at least two amplitude settings. The method comprises operating the vibratory mechanism (2) in one of said at least two amplitude settings; maintaining a predefined phase angle by controlling the vibration frequency of the vibratory mechanism (2); monitoring a bouncing indication value (BIV), said bouncing indication value being calculated based on an acceleration signal indicative of the vertical acceleration of the roller drum (3); and turning off the vibratory mechanism (2) upon detection of a resonance meter value (BIV) that exceeds a predetermined bouncing value (BV), thereby preventing the vibratory roller from operating in a bouncing mode of operation.

Methods and apparatuses for compacting soil and granular materials are disclosed. In some embodiments, the soil compaction apparatuses include an arrangement of diametric expansion elements that, in their expanded state, form a larger compaction surface. In another embodiment, a compaction chamber can be provided with diametric restriction elements and a flow-through passage in the upper portion of the chamber exterior of a drive shaft. The diametric expansion or restriction elements can be fabricated from, for example, individual chains, cables, or wire rope, or a lattice of vertically and horizontally connected chains, cables, or wire rope. Embodiments of the soil compaction apparatus include, but are not limited to, closed-ended driving shafts, open-ended driving shafts, flow-through passages, no flow-through passages, removable rings for holding the diametric expansion/restriction elements, and any combinations thereof.
