Spiral flexure springs in single phase linear-resonant motors

In this paper, the finite element method (FEM) is used to design a spiral flexure bearing that suits a previously designed reciprocating linear motor. Stroke, maximum stress, axial and radial stiffness are the main parameters that have been taken into account in designing the flexure bearing. Moreover, stacks are designed taking into account the change in the system mass due to the part of the flexure bearings that is included. The design is then validated experimentally.
