Patent number: 11031888Abstract: The invention relates to a method for operating a rotating electric machine (1) having a rotor (3), a polyphase excitation winding (5) and a commutation apparatus (9) for commutating excitation winding currents of the excitation winding (5) depending on rotor position values (R) for rotor positions of the rotor (3). First measurement values (A) for the rotor positions are detected by means of a first sensor apparatus (13) and second measurement values (B) for the rotor positions are detected by means of a second sensor apparatus (15). For the commutation of the excitation winding currents, the rotor position values (R) are formed from weighted mean values (M) of the first measurement values (A) and the second measurement values (B).Type: GrantFiled: July 5, 2016Date of Patent: June 8, 2021Assignee: Vitesco Technologies Germany GmbHInventors: Andreas Schnell, Michael Winkler, Emanoil Iordache

Patent number: 10439523Abstract: In a method for controlling an operation of an electric motor, electric voltages applied to electric phases of the electric motor are generated and output in a modulation in a controlled manner dependent on a rotor position of the electric motor and a target/actual comparison of at least one first variable which characterizes a load on the electric motor or an actual rotational speed of the electric motor. A rotor position angle, which characterizes the rotor position, is complemented with a specified preliminary control angle and another regulated preliminary control angle component upon reaching a field weakening range of the electric motor so as to form a sum angle. The sum angle is used to characterize the rotor position in the modulation upon reaching the field weakening range. The disclosure also relates to a device for controlling an operation of an electric motor.Type: GrantFiled: May 28, 2015Date of Patent: October 8, 2019Assignee: Conti Temic microelectronic GmbHInventors: Patrick Hinze, Andreas Schnell, Andreas Schulze

Patent number: 9577568Abstract: A method recognizes a wire-break fault during operation of a brushless DC motor. A switch-on delay duration of a transition of an electrical phase potential that rests on the stator winding phase from a switch-off potential to a switch-on potential and a switch-off delay duration of the transition of the phase potential from the switch-on potential to the switch-off potential are detected for a stator winding phase of the stator winding of the motor during each pulse width modulation cycle period. Moreover, a lower deviation limit is defined for a deviation of detected switch-off delay durations from detected switch-on delay durations. A wire-break fault is deduced if the deviations of the detected switch-off delay durations from the detected switch-on delay durations fall below the lower deviation limit.Type: GrantFiled: May 28, 2014Date of Patent: February 21, 2017Assignees: Conti Temic Microelectronic GmbH, Continental Automotive GmbHInventors: Robert Istvan Loerincz, Andreas Schnell

Patent number: 8454564Abstract: A device for applying a lock solution in a catheter or other access system comprises a syringe (302) having an expulsion arrangement (305, 311) for expelling the lock solution from the device, said expulsion arrangement including a plunger (305) arranged in a housing (304), further comprising a sterile connector (303) for connecting the syringe (302) to the catheter. The connector (303) is arranged to engage a tip (307) of the expulsion arrangement (305, 311) tightly when the syringe (302) is inserted in the connector (303). The connector (303) is arranged to prevent the tip (307) of the expulsion arrangement (305, 311) from entering the catheter. The tip (307) is frangible. A method of applying a lock solution in a catheter or other access system is also disclosed.Type: GrantFiled: June 15, 2005Date of Patent: June 4, 2013Assignee: Gambro Lundia ABInventors: Reinhold Deppisch, Werner Beck, Ruth Dietrich, Björn Frederik Seidler, Andrea Schnell, Claudia Hildwein
