Abstract
A suspension system for an exciter device. The exciter device includes a piston extending through an opening of a moveable housing and generates a vibrational force by causing a linear reciprocating movement of the housing relative to the piston. The suspension system includes an axial suspension magnet fixedly coupled to the housing and positioned proximate the opening. The axial suspension magnet is configured to oppose a magnetic field of a permanent magnet that is fixedly coupled to the piston and the opposing magnetic fields dampen movement of the housing relative to the piston as the first axial suspension magnet approaches the permanent magnet. A radial guide bushing is positioned within the opening surrounding a circumference of the piston. The radial guide bushing is formed of a compressible and flexible material and is configured to restrict radial movement of the housing relative to the piston.
