Abstract
An electric linear repetitive pulsed drive for an operation of apparatuses, in particular for an operation of apparatuses for improving an efficiency of which a working energy that is output in a pulsed manner, with at the same time low repetition frequencies, is advantageous, includes a magnetic circuit with an air gap and an electric coil, a magnetic shape-memory adjustment element and a reset unit, and a control electronics unit, wherein the electric linear repetitive pulsed drive outputs its energy in discrete-time fashion, bundled in short time intervals, that is in pulses.
Claims14
An electric apparatus, comprising:
- at least one electric linear repetitive pulsed drive configured to output working pulses, the at least one electric linear repetitive pulsed drive comprising:
- a magnetic circuit with an air gap and an electric coil,
- a magnetic shape-memory adjustment element and a reset unit, and
- a controller, wherein
- the electric linear repetitive pulsed drive repetitively outputs the working pulses in discrete-time intervals,
- wherein to thereby minimize a reset time of the pulsed drive, the controller is further configured to output an inversely polarized current pulse as a deletion pulse, which is initiated in the reversal point of the working pulse, to bring the magnetic shape-memory adjustment element that is situated in the air gap of the magnetic circuit into a fast expansion, wherein the current pulse abruptly deletes the magnetic field of the magnetic circuit, as a result of which the adjustment element is brought back to its original length by a reset spring of the reset unit.
An electric apparatus, comprising:
- an electric coil;
- a magnetic circuit magnetically coupled to the electric coil, the magnetic circuit having a magnetic core with an air gap;
- a magnetic shape-memory element located in the air gap of the magnetic core, the magnetic shape-memory element being deformable by a magnetic field produced from the magnetic circuit;
- a controller electrically connected to the electric coil, the controller being configured to repeatedly output discrete-time pulses to elongate a length of the magnetic shape-memory element within the air gap by energizing the magnetic circuit.
An electric apparatus, comprising:
- at least one electric linear repetitive pulsed drive configured to output working pulses, the at least one electric linear repetitive pulsed drive comprising:
- a magnetic circuit with an air gap and an electric coil,
- a magnetic shape-memory adjustment element and a reset unit, and
- a controller, wherein
- the electric linear repetitive pulsed drive repetitively outputs the working pulses in discrete-time intervals,
- wherein the reset unit further comprises a further actuated magnetic shape-memory adjustment element configured to minimize a rise time of the electric linear repetitive pulsed drive, wherein the reset unit is free of a reset spring.
An electric apparatus, comprising:
- at least one electric linear repetitive pulsed drive configured to output working pulses, the at least one electric linear repetitive pulsed drive comprising:
- a magnetic circuit with an air gap and an electric coil,
- a magnetic shape-memory adjustment element and a reset unit, and
- a controller, wherein
- the electric linear repetitive pulsed drive repetitively outputs the working pulses in discrete-time intervals,
- wherein a noise production of the magnetic shape-memory adjustment element of the pulsed drive is reduced by noise-optimizing courses of the rise and fall curves of the magnetic field and the apparatus is without a performance-affecting acoustic damping of the cinematics and without a housing that encompasses the electric linear repetitive pulsed drive.
