More Information
Summary: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.
