Linear electric device

An electric device comprising:

• a driveshaft having a first end and a second end and disposed along a driveshaft axis;
• a driveshaft electric power assembly disposed about the driveshaft axis and colinear with the driveshaft axis, the driveshaft electric power assembly comprising a rotor assembly affixed to the driveshaft and a stator assembly encircling the driveshaft and radially outward of the rotor assembly;
• and
• a plurality of power generation assemblies disposed about the driveshaft axis radially outward from the driveshaft electric power assembly, each power generation assembly defined along a power generation assembly axis that is parallel with but spaced radially apart from the driveshaft axis, wherein each power generation assembly comprises at least one set of windings carried by a stator cylinder defined along the power generation assembly axis, the stator cylinder having a first end and a second end with the windings disposed along at least a portion of the stator cylinder between the first and second ends and about the power generation assembly axis, and each power generation assembly further comprising at least one magnet disposed on a magnet slide assembly axially movable within one of the stator cylinders along the power generation assembly axis.

An electric device comprising:

• a driveshaft having a first end and a second end and disposed along a driveshaft axis;
• a first cam mounted on the driveshaft, the first cam having a first cam hub attached to the driveshaft and a first circumferential cam shoulder extending around a periphery of the first cam hub, the first circumferential cam shoulder having a first cam radius and a first curvilinear shape with a first surface and an opposing second surface, the first circumferential cam shoulder having at least two lobes formed by the first curvilinear shape, each lobe characterized by a peak positioned between a first trough and a second trough and a lobe wavelength between the two troughs, the peak having a maximum amplitude for the lobe;
• a power generation assembly defined along a power generation assembly axis, the power generation assembly axis being parallel with but spaced apart radially outward from the driveshaft axis and movably coupled to the first cam;
• a first hydraulic passage extending from one of the first and second driveshaft ends to a first outlet and a second hydraulic passage extending from one of the first and second driveshaft ends to a second outlet spaced apart from the first outlet;
• a first pressure chamber formed by the first cam hub adjacent the driveshaft and a second pressure chamber formed by the first cam hub adjacent the driveshaft, the second pressure chamber spaced apart and separate from the first pressure chamber, wherein the first outlet is in fluid communication with the first pressure chamber and the second outlet is in fluid communication with the second pressure chamber.
