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.
Claims22
A motor comprising:
- a motor carrier made at least partially from a sheet metal material;
- a movable motor part arranged for a linear oscillatory motion;
- and
- a spring element that couples the movable motor part with the motor carrier, the spring element having a connection extension,
- wherein the sheet metal material comprises at least one coupling area where the sheet metal material is folded to form a folding edge extending in a direction substantially parallel to a direction of the linear oscillatory motion of the movable motor part and two layers of sheet metal material extending from the folding edge and facing each other, the two layers comprising a proximal layer that is proximate to the spring element and a distal layer that is distant to the spring element, wherein each of the layers comprises a slot, the slots being aligned with one another in a direction substantially perpendicular to the direction of the linear oscillatory motion of the movable motor part, and wherein the connection extension of the spring element extends through the aligned slots in the direction substantially perpendicular to the direction of the linear oscillatory motion of the movable motor part.
A linear motor comprising:
- a motor carrier made at least partially from a sheet metal material;
- a movable motor part arranged for a linear oscillatory motion;
- and
- at least two spring elements that couple the movable motor part with the motor carrier, each of the at least two spring elements having at least two connection extensions,
- wherein the sheet metal material comprises at least two coupling areas, each of the at least two coupling areas comprising the sheet metal material folded to form a folding edge extending in a direction substantially parallel to a direction of the linear oscillatory motion of the movable motor part,
- wherein the two layers of the sheet metal material extend from the folding edge to face each other in a close parallel juxtaposition with one another, the at least two layers comprising a proximal layer that is proximate to the spring element and a distal layer that is distant to the spring element,
- wherein the proximal layer includes a proximal slot and the distal layer includes a distal slot, the proximal and distal slots being aligned with one another in a direction substantially perpendicular to the direction of the linear oscillatory motion of the movable motor part, and
- wherein each of the connection extensions of each of the at least two spring elements extends through the aligned proximal and distal slots in the direction substantially perpendicular to the direction of the linear oscillatory motion of the movable motor part.
