A radio communication system for an industrial automation system in which at least a first and a second communication device are redundantly linked to an industrial communication network, wherein the first and second communication devices are each connected indirectly or directly to a particular first radio subscriber station or radio base station and to a particular second radio subscriber station or radio base station via the first communication network connection and via the second communication network connection of the communication devices, where the radio subscriber stations interchange messages about available radio base stations among one another and use the messages to coordinate which of the radio subscriber stations has exclusive authorization for a radio link to a selected radio base station at present or within a definable period.

Redundantly operable industrial communication system, method for operation thereof and radio subscriber station

An electric machine includes a rotor and a stator having a horizontal peripheral direction. The rotor and the stator interact electromagnetically. The stator has a number of offset, radially oriented teeth for a winding, with the teeth being arranged in the horizontal peripheral direction. The teeth are each connected to a tooth cap and to a tooth pole. At least one tooth is formed by two webs, which are spaced part in the horizontal peripheral direction and are oriented radially in the zenith direction, for accommodating a solidifiable, in particular curable, medium between the webs.

The aim is to provide an individual-segment rotor, the construction of which requires low production expenditure. For this purpose, an individual-segment rotor having an axis of rotation and a plurality of laminated core segments () arranged around the axis of rotation is provided. Each laminated core segment () is radially fastened to a separate flexural support (). All flexural supports () are radially retained by at least one fastening ring ().

The present invention describes a wireless network, in particular for automation, realtime and/or industrial applications, having at least two access network nodes and at least one radio station for wireless communication with at least one of the at least two access network nodes, wherein each of the at least two access network nodes uses a data channel selected from a set of available selectable data channels for wireless communication with a radio station assigned to it in each case, wherein a control communication channel which is distinct from the selectable data channels is provided in addition, and each of the at least two access network nodes is embodied for wirelessly sending information messages over the control communication channel and the at least one radio station is embodied for receiving the control communication channel.

Wireless network for automation, realtime and/or industrial applications

An industrial automation system comprising a digital fingerprint that is allocated to a unit requesting access to the automation system and which is based on one or more parameters of a communication between the unit and a fingerprint-determining component of the automation system, wherein the industrial automation system additional comprises the fingerprint-determining component which, during the operation of the automation system, grants the requesting unit access to the automation system and compares the determined fingerprint of the requesting unit with a stored fingerprint.

Industrial automation system and method for safeguarding the system

The invention relates to an electric machine () comprising a rotor and a stator, the rotor having a shaft () and the longitudinal extension of the electric machine () being defined by the shaft axis. The electric machine () can be cooled by means of a cooling circuit, the latter comprising at least one cooling pipe (), which extends essentially in the longitudinal direction of the electric machine (). The cooling circuit comprises a first circular distribution pipe () that forms almost a complete circle, which stretches over one plane, the axis of the longitudinal extension of the electric machine () being essentially perpendicular to said plane. According to the invention: at least one cooling pipe () can be connected in a water-tight manner to the first distribution pipe (); the cooling circuit can be traversed by a coolant and has a first connection (), which allows coolant to be supplied to the cooling circuit; and the cooling circuit has a second connection (), which allows coolant to be evacuated from the cooling circuit. The first distribution pipe () is cast in one piece () from metal and said piece () has openings () for the cooling pipes () at the connection points of the first distribution pipe () to the cooling pipes (). Once installed, the piece () is connected to the housing of the electric machine () so that it can conduct heat and/or forms an integral part of the housing.

Electric machine

Stators for harmonic motors are disclosed. The stators are easy to assemble and include a laminated armature made of sheet metal plates. The laminated armature is formed of a substantially cylindrical laminated star armature with a plurality of radially outwardly oriented pole heads distributed along the circumference of the laminated star armature, and a substantially cylindrical laminated yoke armature having radially inwardly oriented pole teeth and arranged radially outside of and concentrically with the laminated star armature. Each of the pole heads is arranged radially adjacent to a corresponding one of the pole teeth. Windings are applied to the pole teeth before the tooth head sleeve or the laminated star armature are inserted in and joined with th laminated yoke armature.
