Abstract

In some implementations, an energy conversion device may include a magnet assembly in a fixed frame, and first and second printed circuit board (PCB) armatures configured to be independently movable relative to the fixed frame. The magnet assembly may include one or more magnets configured to generate first magnetic flux within an active region. The first PCB armature may include at least a first winding configured to generate second magnetic flux within the active region, and the second PCB armature may include at least a second winding configured to generate third magnetic flux within the active region.
