Abstract: The invention relates to an external stator of a rotating-field machine with internal rotor, which external stator is designed as an internal stator or external stator and which external stator has a number of N stator teeth which together form a number of N/2 tooth groups, and each stator tooth has in each case one pole core and one pole shoe integrally formed thereon, wherein the pole cores are manufactured from a first material, and that in each case one tooth group is formed by two directly adjacently arranged stator teeth which, together with a magnetic return means, are constituent parts of a magnetic circuit, characterized in that, between two adjacent stator teeth of two adjacent tooth groups, there is arranged in each case at least one intermediate element which extends in particular in an axial direction of the stator and which is manufactured from a second material, and in that differs from the first material of the pole cores.

Abstract: A method for starting up an automation machine in a machine series is described. With the method, a software package is automatically generated in a planning system with a step tree. The step tree included in the software package is structured in the form of a graph with edges and nodes, wherein at least some of the nodes comprise start-up data or start-up information relating to the start-up data, and wherein the edges describe permitted transitions between two respective nodes. The software package is executed on a machine or on a unit which is connected with the machine for communication. A planning system for carrying out the method is also disclosed.

Abstract: The invention relates to a variable electrohydraulic valve controller, comprising a piston, which is arranged in such a way that the piston acts on a valve, particularly a gas exchange valve of an internal combustion engine, in order to actuate said valve, a valve hydraulic chamber bounded by said piston, and at least one piston-cylinder unit, which is connected to the valve hydraulic chamber by means of a hydraulic line in which a switching valve is arranged. According to the invention, the piston (14) of the piston-cylinder unit (14, 15) is driven by a drive. particularly a motor.

Abstract: The invention relates to an electric drive system for a battery-powered light vehicle, comprising at least one drive motor, a transmission driven by the drive motor for selecting at least two gears, and an actuator for shifting the transmission into the shifting positions, characterized in that an automated transmission, in particular having a freewheel mechanism, is provided.
