An electromagnetic system having a reaction mass with a field winding embedded therein, a base plate having an inner annular surface and an outer annular surface, and an armature winding coupled to at least a portion of the inner annular surface and at least a portion of the outer annular surface of an upper end portion of the base plate. In operation, directing an electric current in at least one of the field winding and the armature winding causes at least one of the base plate and the reaction mass to move relative to each other. The electromagnetic system can be used for seismic exploration and vibroseis applications, among other uses.

A high strength induction machine, rotor, rotor cage end ring and bar joint, rotor end ring, and related methods are provided. An embodiment of an end ring and bar joint includes a main body adapted to substantially surround a rotor shaft when mounted thereto, a plurality of slots extending inwardly in a radial direction from outer peripheries of the main body, a thicker end ring section extending outwardly from a medial portion of the main body, being thicker than the outer peripheries of the main body, and also being adapted to substantially surround the rotor shaft, and a plurality of bosses extending axially and outwardly from outer peripheral portions in a direction opposite to the thicker end ring section and each adapted to receive an end portion of a rotor bar therein.
