Publication number: 20240022142Abstract: An apparatus for fixing a printed circuit board within a housing of an electric motor, comprising a first housing part, a second housing part, and an insulation part. The insulation part is arranged between the first housing part and the second housing part, such that the housing parts are spaced apart from one another at least in certain portions by the insulation part, including a hard component part and a soft component part. The insulation part comprises at least one spring element for exerting a pressing force on the first housing part. The hard component part comprises at least one hold-down means, having at least one pressure-exerting element. The soft component part is configured to provide a seal between the housing parts. The spring element is arranged on that side of the insulation part which lies opposite to a stop region in the direction of the holding force.Type: ApplicationFiled: June 20, 2023Publication date: January 18, 2024Inventors: Manuel WALTER, Tobias LETTER

Publication number: 20230421012Abstract: A switching disk for contacting windings of a stator of an electric motor, which windings are arranged around an axis of rotation, with a printed circuit board of the electric motor, wherein the switching disk has an annular support structure circumferentially extending around the axis of rotation and multiple contact arrangements for contacting the windings with the printed circuit board, which are held by the support structure. The contact arrangements are each formed by a winding contact for contacting one of the windings, a printed circuit board contact offset therefrom in the radial direction for contacting the printed circuit board, and a coupling element extending in the radial direction and electrically connecting the winding contact to the printed circuit board contact.Type: ApplicationFiled: June 26, 2023Publication date: December 28, 2023Inventors: Manuel WALTER, Tobias LETTER, Madlene SCHMIDT

Patent number: 11637987Abstract: An apparatus and a method for bundling two data channels via a point-to-point connection, is described herein. Sequences of data from a first data channel are transmitted via a first line and sequences of data from a second data channel are transmitted via a second line to a multiplexing apparatus. A data gap having a predefined size is arranged between two sequences of first data in each case. The data from the second data channel are transmitted to a buffer and, if the buffer has been filled with second data having a predefined size, are inserted into the data from the first data channel. A third data channel is formed at the output of the multiplexing apparatus using these first data and second data and is transmitted to a third line. The third data channel therefore has a bundling of sequences of first data and sequences of second data.Type: GrantFiled: January 4, 2021Date of Patent: April 25, 2023Assignee: Conti Temic microelectronic GmbHInventors: Alexander Brandhuber, Karsten Breuer, Thomas Wichmann, Manfred Gantner, Manuel Walter

Patent number: 11584087Abstract: Disclosed is a method of providing control data for an additive manufacturing device. The method includes accessing computer-based model data of at least a portion of the object to be manufactured, generating at least one data model of a region of a building material layer to be selectively solidified for manufacturing the at least one object portion. The data model specifies solidification of the building material, and the end point of the at least one solidification path a set of energy introduction parameter values is specified which generates a reference value for the radiation power per unit area in the radiation impact area of the beam bundle on the building material which is lower than the reference value for the radiation power per unit area at other locations of the solidification path, and providing control data corresponding to the generated at least one data model for generating a control data set for the additive manufacturing device.Type: GrantFiled: April 11, 2019Date of Patent: February 21, 2023Assignee: EOS GmbH Electro Optical SystemsInventors: Joerg Hamann, Peter Holfelder, Ludger Huemmeler, Manuel Walter

Patent number: 11431229Abstract: A device (1) to reduce harmful bearing voltages in an electrical machine (M) fed by a DC link voltage of a DC link. The electrical machine has a rotor (2) and a stator (3) with windings (W), and is insulated to ground. At least two bearings (4), with an outer bearing ring (4a) and an inner bearing ring (4i), are between the rotor (2) and the stator (3). A shielding arrangement (S) is between the windings (W) of the stator (2) and the respective outer bearing rings (4a). A stator electrical connecting arrangement (5) is connected to a potential that is stable with respect to the DC link.Type: GrantFiled: February 5, 2020Date of Patent: August 30, 2022Assignee: ebm-papst Mulfingen GmbH & Co. KGInventors: Sebastian Schroth, Manuel Walter

Patent number: 11081942Abstract: An apparatus (1) for reducing bearing voltages in an electric machine (M) with a rotor (2) and a stator (3). A rotor-side and stator-side bearing outer ring (4r, 4s) and a respective bearing inner ring (4i) are provided between the rotor (2) and stator (3). A connection electronics system connect with the motor (M). A compensation arrangement (20) adjusts the potential (ULA-stator) of the bearing voltage at the bearing outer rings (4r, 4s) and the respectively corresponding bearing inner ring (4i) to an identical value. The compensation arrangement (20) comprises an impedance (ZKOMP), of at least one first impedance (ZKOMP, R) between the stator (3) and the rotor-side bearing outer ring (4r). The impedance (ZKOMP) has at least one impedance (ZKOMP. S) between the stator (3) and the stator-side bearing outer ring (4s).Type: GrantFiled: November 18, 2019Date of Patent: August 3, 2021Assignee: ebm-papst Mulfingen GmbH & Co.
