Method for testing a sheet metal section of a sheet metal layer for a rotor of an electrical machine

摘要

The invention relates to a method for testing a sheet metal section (10) of a sheet metal layer for a rotor of an electrical machine, in which the sheet metal section (10) is subjected to at least one strength test in which a number of load changes are applied to the sheet metal section (10) under at least one predeterminable load ) is exercised, characterized in that: - at least a first relationship is determined by means of the strength test, which assigns the load to the number of load changes, - at least one simulation is carried out by means of an electronic calculating device, by means of which at least one rotational speed of the sheet metal section (10) determined, which causes the load associated with the first connection of the number of load cycles; and - based on the determined speed and the first relationship at least a second relationship is determined, which assigns the determined speed of the number of load changes.
