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. 本发明涉及定子和转子叠片的自适应激光接合的装置和方法，其允许单个叠片以较低的能耗接合。使用传感器(4)检测接合点，传感器(4)通过滤波器(5)将信号传送到第微控制器(7)，在第微控制器(7)中处理信号并且继而将信号发送到第二微控制器(8)，然后第二微控制器(8)提供对激光束的正确触发、延时、或调制。微控制器中的软件允许利用可调整的参数任意地调制连续激光束，或触发每个间隙的任意数量的脉冲。该系统允许使用脉冲以及连续激光源(11)。
