Abstract: A motor unit having a motor having a stator and an armature, the armature being arranged for relative driven motion with respect to the stator. A motor control unit has a supply circuit for providing a supply voltage at the motor to provide a set power level to the motor for driving the armature into motion. A measurement circuit is measuring a value of a physical variable indicative of a current flow through the motor, The motor control unit is arranged to interrupt the provision of the supply voltage by the supply circuit and to dynamically brake the motor during a braking time interval and further to measure the value of the physical variable during the braking time interval.
Abstract: The present invention relates to cutting body hair such as beard stubbles of multidays' beard. More particularly, the present invention relates to a cutter system for an electric shaver and/or trimmer, comprising a pair of cooperating cutting elements with two rows of comb-like cutting teeth at opposite edges thereof.

Abstract: A motor and a personal-care device having the motor. The motor has a motor carrier made at least partially from a sheet metal material, a movable motor part, and a spring element that couples the movable motor part with the motor carrier. The sheet metal material comprises at least one coupling area where the sheet metal material is folded so that its two layers are facing each other while each of the two layers comprises a slot, the slots being aligned with one another. A connection extension of the spring element extends through the aligned slots.

Abstract: The present invention is concerned with a skin treatment device, comprising a shaver handle housing, a detachable brush head pivotably supported by the shaver handle housing about at least one brush head pivot axis (I) and a gearing mechanism. The shaver handle housing comprises a drive unit for driving at least one drive pin in a rotatory oscillating manner with a first amplitude about an oscillation axis (II) which is at least substantially perpendicular to the at least one brush head pivot axis (I). The brush head comprises a brush rotatable about a brush axis (III) which is at least substantially perpendicular to the at least one brush head pivot axis (I). The brush comprises at least one driven element coupled to the at least one drive pin by means of the gearing mechanism, wherein the gearing mechanism translates the rotatory oscillating movement of the drive pin into a rotatory oscillating movement of the driven element with a second amplitude which is smaller than the first amplitude of the drive pin.
Abstract: The present invention relates to a cutter system for an electric shaver and/or trimmer, comprising a pair of comb-like cutting elements each with at least one row of cutting teeth and movable relative to each other, wherein one of said cutting elements has thickened and/or rounded tooth tips overhanging the tooth tips of the other cutting element, characterized in that wherein said overhanging rounded tooth tips include a composite thickening which includes an outer shell surrounding an inner core, said shell and said core being made from different materials and wherein said shell is made from metal.

Abstract: A personal hygiene device has a drive unit having a support, a stator fixedly mounted at the support, and an armature spring-mounted at the support for driven linear oscillating motion along a first longitudinal direction parallel to or coinciding with an x-axis of an x-y-z coordinate system. The armature has a center of gravity located in rest at a coordinate [xa, ya, za], and a drive shaft fixedly coupled with the armature and having a center of gravity located in rest at a coordinate [xd, yd, zd]. A first treatment head assembly, detachably connected to the drive shaft, has a center of gravity located in rest at a coordinate [xt1, yt1, zt1]. A secondary mass element, spring-mounted at the support for essentially linear oscillating motion along the first longitudinal direction, has a center of gravity located in rest at a coordinate [xm, ym, zm].
