Linear electric generator having an improved magnet and coil structure, and method of manufacture
First Claim
1. A linear electric generator, comprising:
- a plurality of windings aligned along an axis;
at least one magnetic armature arranged to be moved relative to the windings along the axis upon application of an external force; and
at least one accelerating element provided at an end of said axis to apply a force to the magnetic armature in order to reverse its direction of travel and accelerate its motion, wherein said magnetic armature includes at least one magnetic pole structure having poles of N-S alternating polarities arranged in series.

Abstract
Linear electric generators include stationary windings and armature magnets arranged to reciprocate axially relative to the windings, or stationary magnet structures and movable windings arranged to reciprocate relative to the stationary magnet structures. The armature magnets or stationary magnet structures are in the form of multiple pole magnets made up of a plurality of individual pole structures, each pole structure including a pair of magnets joined to each other with facing poles of like polarity. In addition, the windings may be in the form of a double winding structure including at least one first clockwise winding and at least one second counterclockwise winding arranged in a multi-layered stacked arrangement.
