Patent number: 9450465Abstract: In a method for producing a stator winding of a stator, an auxiliary element is positioned with its central axis in alignment with a central axis of the stator. Bobbins are arranged on the auxiliary element in uniformly spaced-apart relationship around the central axis of the auxiliary element, and a circuit carrier is arranged on the auxiliary element radially inside the bobbins. Coils are formed by winding a conductor wire for each phase of the stator winding onto a corresponding one of the bobbins and routed via the circuit carrier to another one of the bobbins of this phase and wound thereon. Each of the bobbins is pivoted with the coils about a pivot so as to enable the bobbins to pivot up onto radially outwardly protruding stator teeth of the stator from radially outside.Type: GrantFiled: August 27, 2013Date of Patent: September 20, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Rainer Eckert, Jürgen Pawellek

Patent number: 8188628Abstract: In order to connect an angle measuring device to a brushless direct-current motor, a coupling is used, the coupling halves (10, 28) of which are each attached to the rotor (46) of the motor and/or the rotor (42) of the angle measuring device. Instead of using a coupling that is rotationally symmetrical at arbitrary angular positions as in the prior art, a coupling is used in which the coupling halves (10, 28) can be connected to one another only in a finite number of relative angular positions. An adjustment must be made before the coupling halves (10, 28) are attached to the respective rotors (46, 52). This allows all subsequent adjustment to be omitted, for example, even for maintenance work.Type: GrantFiled: March 13, 2008Date of Patent: May 29, 2012Assignee: Siemens AktiengesellschaftInventors: Hubertus Bähr, Rainer Eckert, Udo Grossmann, Hans-Joachim Müller

Patent number: 8159099Abstract: The aim of the invention is to increase the degree of automation in the production of an electrical machine. Particularly, the aim is to be able automate the connection of the coils of an electrical machine. For this purpose, provision is made for the coil ends (17) to be connected using at least one busbar (20, 22). The ends (23) of the respective busbars (20, 22) are hot crimped or welded to the associated end (17) of the coil. Thus, it is possible to eliminate manual drilling and welding of the coil ends. Moreover, the hot-crimped and welded connections have a high degree of electric strength and a high current carrying capability.Type: GrantFiled: April 30, 2008Date of Patent: April 17, 2012Assignee: Siemens AktiengesellschaftInventors: Ehrfried Dümpert, Rainer Eckert
