摘要： The invention relates to a brake device having a frame, at least one pair of mutually opposing braking elements, at least one actuation element in operative connection with each braking element, and a spring device, wherein each braking element has three joint sections which are arranged in a row and are connected to one another via flexure bearings, and the middle joint section of which has a contact section, and the two joint sections adjoining the middle joint section are each connected integrally to the frame via a flexure bearing, wherein a force is exerted on each braking element by means of the spring device, by means of which force the respective contact section can be pressed with a defined force against an element to be braked, and a force which counteracts the force exerted on the braking elements by the spring device acts on the braking elements by means of a continuous energy input into the actuation elements and, when the energy input into the actuation elements is absent, the force exerted by the latter on the braking elements is removed.

摘要： A kinematic system is provided having a more efficient calculation of the direct and/or indirect kinematics. The direct/indirect kinematics of a kinematic system are estimated on the basis of local support points. In particular, when estimating the indirect kinematics, an interpolation is used which, for poses in a determined spatial unit, is based on predetermined configuration vectors which are each associated with a boundary point of the determined spatial unit in accordance with the indirect kinematics. When estimating the direct kinematics, an interpolation is used which, for configuration vectors in the determined spatial unit, is based on predetermined poses of the kinematic system which are each associated with a boundary point of the determined spatial unit in accordance with the direct kinematics.

摘要： The present invention relates to a magnetic guiding device having a stator and a slide movable along a guiding direction relative to the stator, the stator and the slide being magnetized or magnetizable such that a magnetic field extending through the stator and the slide generates a magnetic supporting force on the slide acting along the guiding direction. To improve the running properties of the slide by avoiding differential slip, jerking and varying friction, according to the invention, the magnetic field extending through the stator and the slide simultaneously generates a magnetic pretensioning force which urges the slide and the stator against each other.

摘要： A control device and a control method for a piezoelectric inertia motor are provided. In the stick phase, a first switching element and a second switching element are switched in directions opposite to one another by pulse width modulation, where a time component of a first switching state of ON and OFF increases relative to a time component of a second switching state of ON and OFF, the pulse width modulation is filtered by the capacitive piezoelectric actuator and an inductance, and a first charging operation is carried out, and the time components of the first switching state and the second switching state are reversed at the beginning of a slip phase, and thereby carrying out a second charging operation in the opposite direction to the first charging operation at the capacitive piezoelectric actuator. By storing electromagnetic energy in the inductance, the configuration provided allows for the reduction of energy dissipation as heat and can contribute to an energy-efficient drive for inertia motors.

摘要： The disclosure relates to an ultrasonic actuator formed of a plate having a base, a cover surface which is geometrically similar to the base, and a lateral surface which interconnects the base and the cover surface, wherein the plate includes an electromagnetic material. Electrodes for inciting periodic deformations of the plate are arranged on the base of the plate and on the cover surface of the plate opposite the base. The base includes at least two faces which are arranged in parallel with one another and form contact portions of the lateral surface, and the two faces of the base arranged in parallel with one another, together with connecting lines which interconnect the respective end points of the faces arranged in parallel, form a parallelogram inscribed in the base, in which parallelogram an angle different from 90° is enclosed between adjacent faces. A motor having such an ultrasonic actuator is also disclosed.

摘要： A motion control system and method for controlling a stick-slip piezo motor includes an electronic controller and an analog driver for moving a mechanical device. When operating in a digital circuit mode, an electronic controller controls a digital-to-analog converter for moving the stick-slip piezo motor at a low speed. When operating in a faster analog circuit mode, the electronic controller, via an analog driver, operates to control an analog hardware circuit to move the stick-slip piezo motor at a high speed. The electronic controller operates in the digital circuit mode at start-up of the piezo motor.

摘要： Disclosed is a linear adjuster, comprising: a spindle-and-spindle-nut mechanism, a first adjustment part, and a second adjustment part. The first adjustment part comprises a first main body and a first stop device. The second adjustment part comprises a second main body and a second stop device. The first adjustment part and the second adjustment part may be moved relative to each other by means of the spindle-and-spindle-nut mechanism which comprises a spindle longitudinal axis (L3). The first stop device and the second stop device come to a stop state when the linear adjuster performs a retraction travel movement or an extension travel movement and the first adjustment part and the second adjustment part are in a predefined stop travel position relative to each other. A positioning device, a positioning assembly and a method for repairing a linear adjuster.

摘要： The present disclosure relates to a piezoelectric stick-slip-motor and control method. An exemplary method to enable speed variation of the piezoelectric stick-slip-motor with a reduced noise generation, includes: applying a cyclic sawtooth-waveform drive voltage signal with a constant frequency in which the drive voltage (V) increases to and decreases from a peak voltage (Vp) for operating the motor with a constant speed; and changing the motor speed by gradually increasing or decreasing the gradient (dV/dt) of increasing the drive voltage (V) to the peak voltage (Vp) with each subsequent sawtooth-waveform drive voltage signal cycle (C) while keeping the frequency of the drive voltage signal constant.

摘要： A biaxial positioning device is described. The positioning device includes: a stationary base element; a first positioning element movably mounted relative to the base element along a first direction by means of a first guide device; a second positioning element movably mounted relative to the first positioning element along a second direction, which is different to the first direction, by means of a second guide device; a first drive for adjusting the first positioning element along the first direction of movement; and a second drive for adjusting the second positioning element along the second direction of movement. The stationary base element and the second positioning element each have a printed circuit board, and the first positioning element is a metal support element and is disposed between the base element and the second positioning element.

摘要： The present disclosure relates to an electromechanical linear drive having a housing, an electromechanical drive unit, a transmission element which is coupled to the electro-mechanical drive unit, and an element to be driven which is in frictional contact with the transmission element, where the transmission element is mounted on at least two bearing points with respect to the housing. Improved accessibility to the element to be driven and a longer adjustment path of the element to be driven can be achieved by placing the element to be driven in frictional contact with the transmission element at a point of engagement outside of all bearing points.
