Definitions
- the invention relates to an actuator according to the preamble of claim 1 and the use of an actuator.
- actuators are based on the use of piezocrystals or electroactive polymers. These materials change their internal structure by applying electrical voltage and can thereby trigger movements.
- Electromagnetic actuators for actuating a Stellglie ⁇ must be mass-produced in large quantities and thus cost-effectively.
- an electromagnetic actuator for actuating a valve stem is known, which is in communication with a movable against the force of at least one return spring armature.
- an electromagnet is arranged with a housing.
- a compact structure which also provides the necessary elements for mounting and assembly to a complete electromagnetic ⁇ actuator actuator on the arrangement of a housing for receiving a yoke provided with the coil of the electromagnet.
- the design of the electromagnet is already advantageous for mass production, since here with only a few joining operations, the assembly of the entire device is possible.
- the object of the invention is to further develop an actuator for generating pulses or vibrations such that their amplitude and frequency can be controlled independently of one another.
- the invention includes an electromagnetic actuator having at least one electromagnet and a linearly movable structural unit, said movable structural unit zuei ⁇ Nander spaced permanent magnets includes, between which the at least one electromagnet is arranged.
- the invention is based on the consideration that an actuator can be realized with a small size for the generation of pulses or vibrations.
- the basic principle of the actuator is based on magnetic recoil, comparable to that of electromagnetic motors.
- the application of alternating current produces a vibration as a function of the alternating current frequency.
- Permanentmag ⁇ designated oscillate by alternating attraction and repulsion.
- a linear movement takes place, as a rule parallel to egg ⁇ ner symmetry axis of the movable unit.
- the use of DC voltage enables the generation of strong single pulses, by attracting one side and simultaneously repelling the other.
- the amplitude and the frequency can be controlled independently of each other.
- the kinetic energy is released at the end of the movement space in the form of shockwaves.
- a particular advantage of the invention is that the actuator is versatile because of its small size, high efficiency and low power consumption. By use in a variety of different electronic devices this can also be used for the generation of a haptic or acoustic feedback. Thus, flexibly controllable individual impulses or vibrations are possible in one device.
- the at least one electromagnet can have a central recess through which an axis of the movable structural unit passes.
- the permanent magnets may be disposed at the respective ends of the axle.
- the position of the permanent magnets mounted on the axle can be changed, thereby generating pulses or vibrations.
- the optimal Anord ⁇ planning this leads to a higher efficiency of the electric coils and consequently to a collapsible energy consumption of the actuator.
- the permanent magnets can be arranged opposite to ⁇ pole to each other. Due to this arrangement can be on an additional mechanical suspension of the moving mass, which would limit the power and agility and would lead to a auch ⁇ ren energy requirement, be dispensed with.
- the axis may consist of diamagnetic material.
- the magnets are then ⁇ example by a diamagnetic rod or rod bar ⁇ connected.
- Composite materials made of different materials with diamagnetic properties can also be used for the production of the connecting axle.

- the guide bushing of paramagnetic Mate ⁇ rial can be made.
- the axis is then enclosed between the Permanentmag ⁇ Neten of a paramagnetic socket.
- These paramagnetic sleeve is wound with insulated wire, the coils ⁇ development and so gives an electromagnet having an axial magnetization, which occurs in direct interaction with the permanent magnets.
- the socket may also be part of a paramagnetic core of the coil. All materials with paramagnetic properties can be used for bushing.
- the guide bush made of doped glass, doped carbon fibers, bronze, brass or stainless steel. Some of these materials also are particularly suitable as sliding and can be used with low wear and low friction coefficient in the corresponding work ⁇ mating material.
- the at least one electromagnet can have a paramagnetic housing.
- the entire casing of the magnet is paramag ⁇ genetically.
- a sliding bushing can be designed.
- a surrounding housing may be present through which an extended end of the axle passes outwardly.
- actuators for example in the automotive industry, can also be actuated with the actuator.
- a completely enclosing housing may be present.
- the housing can also fluid-tight are ⁇ staltet without further openings. Such housings are preferably used in vibration actuators.
- the electromagnetic actuator can be used as a vibration actuator.
- the electromagnetic actuator can be used as a vibration generator for generating acoustic signals.
