Reciprocating Linear Alternator (RLA)-Image

Umbra's Reciprocating Electro-Mechanical Linear Alternators (RLA's) are an ideal technology for power generation from alternative energy sources such as compressed gas and ocean waves.

The aerospace-inspired, corrosion resistant, scalable architecture dramatically simplifies hydrokinetic designs and reduces operational/maintenance costs.

How they work:

Umbra RLA's leverage the ability of a ball-screw to be back-driven to directly convert reciprocating linear motion into electricity without the use of gears or linkages. As an external energy source translates the ball-screw shaft back and forth, a ball-nut with bonded permanent magnets spins to induce the flow of electricity in the adjacent stator windings.

Contact the Umbra Group to learn more about custom designs for these compact, power-dense devices.
