Patent number: 9746492Abstract: In a method for checking the plausibility of sensor signals, a first sensor element detects at least one first physical quantity and outputs it as a first sensor signal, and a second sensor element detects a second physical quantity correlated with the first physical quantity and outputs it as a second sensor signal. The first sensor element has a first reliability range having an upper limit and/or a lower limit, which range is related to the second physical quantity. The first physical quantity detected by the first sensor element is recognized as plausible if the second physical quantity detected by the second sensor element lies within the corresponding first reliability range of the first sensor element.Type: GrantFiled: September 27, 2012Date of Patent: August 29, 2017Assignee: ROBERT BOSCH GMBHInventors: Christian Rauh, Christian Korn, Olaf Koerner, Stephan Rittler, Hansjoerg Markus Hild

Publication number: 20150372568Abstract: An electromechanical transducer includes at least one rotor which is arranged on a shaft and is arranged in an encapsulated stator. The stator has a laminated core and a winding which are surrounded by an insulating cooling fluid. The cooling fluid can be introduced via first cooling ducts which are arranged radially with respect to the shaft in the center of the stator and can be discharged at each axial end of the stator radially with respect to the shaft via second cooling ducts in the winding head region, or vice versa. As a result it is possible to provide a compact and robust electromechanical transformer which owing to its lightweight design with a high torque density is suitable for use, for example, in aircraft or other vehicles.Type: ApplicationFiled: January 17, 2014Publication date: December 24, 2015Applicant: Siemens AktiengesellschaftInventor: OLAF KÖRNER

Patent number: 8487559Abstract: A diesel-electric drive system includes a generator having two multi-phase winding systems, a diesel engine, and a DC-link converter. Two self-commuted pulse power converters on the generator side are linked to the windings systems and to each other by a brake resistor on the alternating voltage side. The brake resistor is split into two series-connected resistors, each having half the resistance value of the brake resistor. An input of a bipolar switching device is connected to a connecting point of two series-connected resistors. The capacity of the diesel motor can then be checked in a self-load test with a controllable load torque of the diesel-electric drive system, while eliminating overloads of the power semiconductors of the self-commuted pulse power converters on the generator side.Type: GrantFiled: March 27, 2009Date of Patent: July 16, 2013Assignee: Siemens AktiengesellschaftInventors: Andreas Holweck, Olaf Körner
