  • Patent number: 9385578
    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.
    Type: Grant

  • Patent number: 9301822
    Abstract: The personal care appliance (10) comprises a handle/housing (20), a workpiece assembly (12), a motor assembly (18) which is mounted to the handle for driving the workpiece assembly and a secondary resonator (30) connected to the motor assembly or the handle, the secondary resonator comprising a spring mass assembly characterized in that at resonant operation thereof, vibrations produced by action of the motor assembly which would otherwise be transmitted to the handle, are significantly reduced/cancelled.

  • Patent number: 8970072
    Abstract: A magnetic spring arrangement for a resonant motor including a housing, magnets fixed in position at opposing ends of the housing, a magnet 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 and an AC drive signal, wherein an applicator member is attachable to the moving magnet for corresponding movement of a workpiece portion of the applicator member.

  • Publication number: 20100186179
    Abstract: A workpiece system with a reciprocating motion which includes a motor assembly for producing an output drive signal with a periodic force pulse. The drive signal is coupled to a driven member assembly through a magnetic arrangement, wherein the driven member assembly has a workpiece mounted thereon with a return spring assembly. The driven member assembly has a resonant mechanical frequency. As the RPM of the motor increases from zero following startup, the drive signal frequency increases to the point very near resonance, where the energy from the drive signal is transferred into the reciprocating motion of the driven assembly, producing an effective amplitude of workpiece motion.
