Patent number: 11648099Abstract: An actuator (12) for a personal care appliance (10) having an eccentric core (21) to preload the actuator (12) to prevent rattling caused by detrimental reactionary forces. The eccentric core (21) includes a pole assembly (24) radially extending from a spindle 22 having at least a first set (25-1) and a second set (25-2) of pole members. The first set (25-1) has a greater length as measured from the center of the spindle 22 than the second set (24-2), reducing the magnet gap on one side of the spindle (22) to create an eccentric core and preload the actuator (12). Alternatively, the preload can be mechanically created by a set of bearings (28) disposed within housing (18) of the actuator 12, where the bearings (28) have a centerline (A3) offset from the principal axis (A1) of the housing (18).Type: GrantFiled: January 17, 2020Date of Patent: May 16, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Kevin Arnold Miller, Wolter F.
