Patent number: 11387702Abstract: A stator device with a plurality of windings, on a winding carrier, that electromotive interaction with a rotor. The windings are parallel to one another and to the center axis. The windings can be individually electrically contacted with winding terminals of a winding wire. The windings are assigned to at least two disk-shaped and/or ring-shaped electrically conductive interconnection rings so that they are electrically insulated from one another. The winding terminals are connected using the interconnection ring assigned to this terminal polarity (U; V; W) for external permanent common contact by welding hooks formed on the radial inner side on the interconnection ring. A ring-shaped deflection disk, with deflection pins, is provided in the axial direction on the interconnection end disk.Type: GrantFiled: January 7, 2019Date of Patent: July 12, 2022Assignee: ebm-papst St. Georgen GmbH & Co. KGInventors: Thirza Weiser, Christian Rudel, Achim Honold, Hassan Ghodsi-Khameneh

Patent number: 9232265Abstract: Techniques and mechanisms for determining an operation mode of an audio-video (AV) device. In an embodiment, communication logic of the AV device may be configured at different times for different ones of a plurality of operation modes including an AV source operation mode for providing AV information to another device and an AV sink operation mode for receiving AV information from another device. In response to a detected event, control logic initializes the communication logic of the AV device into a default mode which prevents operation of the communication logic as an AV source.Type: GrantFiled: March 29, 2012Date of Patent: January 5, 2016Assignee: Lattice Semiconductor CorporationInventors: Conrad Arlo Maxwell, Lance Davies, Graeme P. Jones, Glenn L. Marks, Jonathan Regalado-Hawkey, Christian Rudel

Patent number: 8324892Abstract: An electric motor (10) has: a stator (12) and a rotor (14) having a shaft (87). The rotor (14) has a sensor magnet (82) having a number SP of sensor poles (71, 72, 73, 74) for generating a predetermined distribution of the magnetic flux density, such that SP=2, 4, 6, 8, etc. The motor also has at least two rotor position sensors (450, 455, 460, 465) for generating rotor position signals (B_S1, B_S2) characterizing the magnetic flux density, the rotor position sensors (450, 455, 460, 465) being arranged in the region (30) of the circumference of the sensor magnet (82). The motor also has an evaluation apparatus (32) that ascertains, from the rotor position signals (B_S1, B_S2), an absolute value (phi_el, phi_mech) for the rotational position of the rotor (14). A method of generating an absolute value for the rotational position of an electric motor is likewise described.Type: GrantFiled: July 19, 2006Date of Patent: December 4, 2012Assignee: EBM-Papst St. Georgen GmbH & Co. KGInventors: Christian Rudel, Jörg Hornberger, Michael Schäuble, Michael Kisch

Patent number: 7965004Abstract: An electric motor has a stator (12) as well as a rotor (14) rotatable about a rotation axis (85) and a sensor magnet (82) having an even number of sensor poles (71, 72, 73, 74). The sensor magnet (82) is configured to generate a magnetic flux having a magnetic flux density that changes sinusoidally with respect to the rotation angle. Two analog rotor position sensors (460, 465) are arranged on a support structure (468) at a distance from one another such that, during operation, they generate two sinusoidal signals (B_S1, B_S2) having a phase shift of 90° to each other. A signal generator (90) serves to generate at least one pulse-shaped signal (A, B) from the two sinusoidal rotor position signals (B_S1, B_S2) that are phase-shifted by 90°. The instantaneous rotation speed can be accurately determined from this pulse-shaped signal.Type: GrantFiled: November 22, 2006Date of Patent: June 21, 2011Assignee: EBM—Papst St. Georgen GmbH & Co.

Patent number: 7893579Abstract: An electric motor has a stator (224) having a bearing tube (238) made of a magnetically transparent material; it also has a rotor (222) having a rotor shaft (234) that is at least partially journaled in the bearing tube (238), and has a ring magnet (250) that is fixedly arranged on the rotor shaft (234) inside the bearing tube (238). Two magnetic-field-dependent analog sensors (248?, 248?) are arranged on a circuit board (246) outside the bearing tube (238), at an angular distance (PHI) from one another, in order to generate rotor position signals as a function of the rotational position of the ring magnet (250). A corresponding device (150) that serves to control the motor is provided, in order to process these rotor position signals into a signal that indicates the absolute rotational position of the rotor (222).Type: GrantFiled: July 27, 2006Date of Patent: February 22, 2011Assignee: Ebm-Papst St. Georgen GmbH & Co.
