Patent number: 11626769Abstract: An electric machine may be an external rotor motor with a stator and a rotor surrounding the stator. The rotor may be mounted on bearings so as to be rotatable around an axis of rotation relative to the stator, where the mechanical forces transmitted by the bearings of the rotor may be absorbed at least in part by the stator. The stator may have a coil winding for generating a magnetic field, the coil winding being surrounded at least partially by a casting compound. At the output, the mechanical forces of the rotor or the device transmitted by the bearings and taken up by the stator may be introduced into the stator largely via the casting compound. The casting compound thus reduces induced vibrations.Type: GrantFiled: April 18, 2018Date of Patent: April 11, 2023Assignee: Lenze Drives GmbHInventors: Volker Grabs, Matthias Thesseling, Olaf Huebner

Patent number: 10811929Abstract: A motor system includes: a stator; a rotor; a motor shaft, which is mechanically coupled for conjoint rotation with the rotor, and which defines a radial direction and an axial direction of the motor system; heat-generating components, in particular power semiconductors; a control device which is designed to control an operation of the motor system; and a housing. The housing has a first central chamber, wherein the stator, the rotor and the heat-generating components are arranged inside the first chamber, and wherein the heat-generating components are connected to an outer wall of the first chamber, and has a number of second chambers, wherein the second chambers radially surround the first chamber, and wherein the second chambers form closed channels for guiding cooling air.Type: GrantFiled: November 23, 2015Date of Patent: October 20, 2020Assignee: Lenze Drives GmbHInventors: Jan Wettlaufer, Abdenbi Maghnaoui, Torben Jonsky, Volker Grabs, Martin Ehlich

Patent number: 10312838Abstract: A drive system has an electric motor, wherein the electric motor includes a first three-phase stator winding system and a second three-phase stator winding system. The first and the second stator winding system are arranged on the stator in a manner rotated through an electrical phase angle in relation to one another. The drive system includes a frequency converter, wherein the frequency converter has a first bridge circuit arrangement which is designed to generate voltages for the first winding system and a second bridge circuit arrangement which is designed to generate voltages for the second winding system. The first bridge circuit arrangement and the second bridge circuit arrangement are connected in series. A control device is designed to actuate the first bridge circuit arrangement and the second bridge circuit arrangement.Type: GrantFiled: August 19, 2016Date of Patent: June 4, 2019Assignee: Lenze Drives GmbHInventors: Heiko Stichweh, Felix Klute, Torben Jonsky, Thorsten Hohnsbein, Volker Grabs, Holger Borcherding

Patent number: 8170795Abstract: A vehicle navigation system helps guide a driver to a destination by enhancing visualization of upcoming intersections. The navigation system stores animation data that depicts the intersection as it will appear to the driver. The animation data may be a sequence of images (e.g., digital camera images) taken at intervals before and after the intersection. The navigation system may show the images in synchronism with the progress of the vehicle to provide an animated display of the intersection for the driver. The animated display aids the driver with following a recommended navigation route to the destination.Type: GrantFiled: August 3, 2006Date of Patent: May 1, 2012Assignee: Harman Becker Automotive Systems GmbHInventors: Christian BrĂ¼lle-Drews, Volker Grabs

Publication number: 20060287819Abstract: A vehicle navigation system helps guide a driver to a destination by enhancing visualization of landmarks and upcoming intersections. The navigation system stores resolution independent representations of the landmarks and intersections. The representations allow the navigation system to quickly and efficiently resize and render the landmarks and intersections without distortion and with reduced computational burden. When the vehicle approaches a landmark or intersection, the navigation system may retrieve the representation, mathematically scale the representation, adjust the perspective of the representation, and render a view of the upcoming landmarks and intersection to aid the driver with reaching the destination.Type: ApplicationFiled: August 28, 2006Publication date: December 21, 2006Inventors: Christian Brulle-Drews, Volker Grabs
