摘要： The invention refers to a switch for interrupting of an electric circuit, in which two direct voltage sources (S1, S2) and at least one load (L) are integrated and mutually interconnected, wherein the purpose of the invention is to interrupt quickly and efficiently such electric circuit in a need, so that after said interruption each potential contact between the load and anyone of said electric voltage sources would have to be eliminated, and moreover, also each potential interaction between said load and any other loads or electric circuits, which might be electrically interconnected with said load, would also have to be eliminated. To this aim, a main electric conductor (10) is in the area between both electric voltage sources (S1, S2) and said load (L) bridged by a supplemental electric conductor (11), which is in parallel electrically connected with said sources (S1, S2) and also with said load (L), and is prior to activation of the switch, namely during regular operation of the electric circuit (1), interrupted by means of a gap (G) and is consequently electrically impermeable, wherein an electrically conductive branch (12) with integrated electric fuse (2) with a melting member (21) is in parallel connected to said main conductor (10) in two apart from each other located connecting points (100', 100'') in the area (100) between both electric voltage sources (S1, S2), while in the intermediate area (1000) between said connecting points (100', 100'') said main conductor (10) is furnished with a removable section (10'), which is in each pre-determined conditions removable apart from the main conductor (10) and irreversibly displaceable into a gap (G) in said supplemental electric conductor (11), which herewith becomes electrically conductive, while simultaneously the main electric conductor (10) upon removing said section (10') there-from becomes electrically impermeable.

摘要： The invention relates to an apparatus and a method of adaptive laser joining of stator and rotor laminations allowing individual laminations to be joined with a lower expenditure of energy. For detecting the joining point a sensor (4) is used, which transmits the signal through a filter (5) to a first microcontroller (7), where the signal is processed and transmitted, in turn, to the second microcontroller (8), which then provides for the correct triggering, delaying, or modulation of the laser beam. The software in the microcontrollers allows arbitrarily modulating the continuous beam with adjustable parameters, or triggering an arbitrary number of pulses per gap. The system allows pulse as well as continuous laser sources (11) to be used.
