Abstract

A family of flexure suspension systems for reciprocating linear motors, especially voice coil type, wherein basic flexure span elements, each a flat spring or typically a stack thereof, are arranged in a folded flexure configuration to suspend a moving armature from a base in a compliant manner with a precise linear stroke path along a central axis. Typically two tiers of folded flexures suspend the armature, each tier having at least two array members, each a balanced quad or triad side-by-side row of span elements, disposed in a plane about the central axis in a polar/radial or rectangular pattern. Inherent overall balance and cancellation of unwanted forces acting on the system components achieve a consistent operating air gap, eliminate undesired torque imposed on the armature, coil, and entire mechanical assembly, and reduce mass and space requirements.
