Abstract: A method for fault recognition in an electric machine controlled by an inverter in a motor vehicle, in which the phase currents of the electric machine are ascertained, in particular ascertained by measuring, and a fault is recognized if at least one of the phase currents or a variable derived therefrom, exceeds a predefined upper threshold value, the upper threshold value being established as a function of operating parameters of the motor vehicle, in particular of the electric machine and/or of the inverter.

Abstract: The invention relates to a method and device for producing metal sections having two profile flanges arranged opposite one another and having flange inner faces that are to be kept apart from each other by a closely toleranced final chamber dimension. In order to adapt the chamber dimension from a starting chamber dimension K0 to a desired final chamber dimension K1, the metal section is passed through the device, which forms working gaps between an inner working roll pair and outer support rolls. The working rolls that form the inner working roll pair roll over each other in order to brace the forming forces exerted on the working roll pair from the flange inner faces against each other.
