Abstract

A magnetic spring arrangement for a resonant motor, comprising: a housing (12), magnets (14, 16) fixed in position at opposing ends (13, 15) of the housing, a magnet (18) positioned within the housing for movement toward and away from the fixed magnets in a reciprocal oscillating motion with a driving action produced by a stator coil (24) and an AC drive signal (26), wherein an applicator member (32) is attachable to the moving magnet for corresponding movement of a workpiece portion (34) of the applicator member.
