Abstract:
A method for producing an electromagnetic actuator that includes two electromagnets (2, 3) arranged at a spacing distance relative to one another, and an armature (1) that is movable back and forth between the electromagnets (2, 3) against the force of two oppositely acting springs (61, 62), said method comprising steps of compressing the springs (61, 62) by a certain compression value in repeating compression cycles so often until a present cycle energy (A1, A2) scored in each said springs (61, 62) due to a compression in a present cycle of said compression cycles no longer or only insignificantly differs from a prior cycle energy stored in the respective said spring (61, 62) in a prior cycle of said compression cycles, and following thereafter, adjusting a pre-tension (F10, F20) of one of the said springs (61, 62) or of both of said springs (61, 62).
