Patent number: 9197116Abstract: The invention relates to an annular rotor having a hollow shaft for an electric machine. In order to allow transport of such a machine, particularly for a very large model, the rotor is divided in the circumferential direction into a plurality of partial annular rotor segments (1). The rotor further comprises a hollow shaft, wherein the closed ring shape of the rotor can be broken by separating the rotor segments (1) from each other.Type: GrantFiled: July 7, 2010Date of Patent: November 24, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Martin Junge, Andreas Jöckel

Publication number: 20150228071Abstract: An apparatus (130) and method for automatically or semi-automatically controlling a collimator (COL) of an x-ray imager (100) to collimate imager (100)'s x-ray beam and adjusting an alignment of the x-ray imager (100) in respect of an object (PAT). The collimation and alignment operation is based on 3D image data (3DI) of the object (PAT) to be imaged. The 3D image data (3DI) is acquired by a sensor (S). The sensor (S) operates on non-ionizing radiation. The 3D image data (3DI) describes a shape in 3D of the object (PAT) and anatomic landmarks are derived therefrom to define a collimation window (W) for a region of interest (ROI). Based on the collimation window (W) the collimator (COL)'s setting and imager (100) alignment is adjusted accordingly.Type: ApplicationFiled: August 26, 2013Publication date: August 13, 2015Inventors: Sascha Andreas Jockel, Christoph Kurze, Dirk Manke

Publication number: 20140028138Abstract: In a method an inner segment is first pre-assembled on each of a number of outer segments by at least one fixing element, so as to produce a plurality of segment modules having each a predetermined air gap between the inner segment and the outer segment. The inner segments and the outer segments are assigned to the rotor or stator of the electrical machine. The inner segments of the plurality of segment modules are fastened to an inner assembly device (for example a hub). The outer segments of the plurality of segment modules are fastened to an outer assembly device (for example a supporting structure). Finally, the fixing elements between the inner segments and the outer segments are removed.Type: ApplicationFiled: March 13, 2012Publication date: January 30, 2014Applicant: Siemens AktiengesellschaftInventors: Kornel Feher, Ulrich Hartmann, Martin Junge, Andreas Jöckel, Martin Kristl, Wilfried Luchs, Oliver Memminger, Joachim Mucha, Axel Möhle

Patent number: 7816824Abstract: The invention relates to an electric motor (1) with permanent magnet excitation, comprising a stator (2), a rotor (8), comprising a hollow shaft (13) on which the permanent magnets (9) are positioned. The hollow shaft (13) is sealed tight against an output shaft (7) at least at the end faces thereof and a suitable coolant is provided in the enclosed cavity (14) which, during operation of the electric motor, evaporates from the relatively hot hollow shaft in the region of the permanent magnets (9) and condenses in the region of the relatively cold output shaft (7) such as to introduce a radial and axial heat transport.Type: GrantFiled: June 8, 2006Date of Patent: October 19, 2010Assignee: Siemens AktiengesellschaftInventor: Andreas Jöckel

Patent number: 7633205Abstract: In order to be able to electric drives in very tight installation spaces, e.g. in propulsion vehicles or machine tools, an electric machine (1) is proposed having a stator and a rotor (28), with the laminations (2) of the stator have axial slots (4) and teeth (5, 6) extending between adjacent slots (4) in direction air gap. At least a predefined number of the teeth (6) is configured as a single-tooth winding (7), and at least one section (3) is provided in circumferential direction of the stator and is designed without slots but follows the contour of the stator bore (11) in the area of the air gap.Type: GrantFiled: November 22, 2004Date of Patent: December 15, 2009Assignee: Siemens AktiengesellschaftInventors: Thilo Hoffmann, Andreas Jöckel

Publication number: 20090289517Abstract: The invention relates to a PM rotor having radial cooling slots and to a corresponding method of production. The aim of the invention is to provide a structurally simple rotor which has a high degree of efficiency. According to the invention, the rotor consists a plurality of partial laminated stacks (20) that are interspaced in the axial direction at a defined distance, thereby defining radial cooling slots (22). Permanent magnets (24) are arranged in every partial laminated stack (20) in inner pockets (23). The dimensions of every permanent magnet (24) in the axial direction does not or only insignificantly exceed the axial dimensions of the respective partial laminated stack (20). During assembly, the permanent magnets (24) can be axially pushed through the inner pockets (23) to the respective partial laminated stack (20). The invention allows to provide a rotor comprising radial cooling slots and inner permanent magnets which has a very high degree of efficiency.Type: ApplicationFiled: December 19, 2007Publication date: November 26, 2009Applicant: Siemens AktiengesellschaftInventors: Andreas Jöckel, Thomas Schmidt

Publication number: 20090234548Abstract: The invention relates to a holding brake for track-bound motor vehicles (1) with the holding brake being realized by means of at least one electric machine (2) which has a rotor and a stator. A control system for the electric machine is hereby provided to so control the operation of the electric machine (2) that the position of the rotor in the stator remains constant when exposed to an external torque. In other words, the electric motor (2) is used as holding brake instead of a pneumatic holding brake. In this way, the holding brake is advantageously not subject to any wear since the holding forces are produced magnetically and not by mechanical forces. In addition, no noise is generated by the use of the holding brake according to the invention. Furthermore, a starting jolt is prevented, when the electric motor (2) used as a holding brake is also used as a drive motor.Type: ApplicationFiled: March 15, 2006Publication date: September 17, 2009Applicant: Siemens AktiengesellschaftInventors: Hans Bergner, Thilo Hoffmann, Andreas Jöckel, Martin Teichmann

Patent number: 6938555Abstract: A traction drive, in particular for rail cars, includes a permanent-excited synchronous motor, a traction converter with a pulsed inverter for powering the motor, and ohmic brake resistors. Cross-over switches are connected with a corresponding input terminal of the motor and can switch the input terminal between a corresponding output terminal of the pulsed inverter (for travel) and a terminal of a corresponding brake resistor (for braking). The brake resistors are electrically connected in a star configuration. The traction drive can operate with different supply voltages. There is no longer a need for a mechanical brake, and flat spots on the wheels can be prevented.Type: GrantFiled: June 7, 2004Date of Patent: September 6, 2005Assignee: Siemens AktiengesellschaftInventor: Andreas Jöckel

Publication number: 20020101081Abstract: An electric motor driven rail vehicle with an internal combustion engine includes at least one generator/motor system with a permanent-magnet-excited synchronous machine or an asynchronous machine. The internal combustion engine and the permanent-magnet-excited synchronous machine or an asynchronous machine are mechanically coupled, preferably through a flange coupling.
