Patent number: 11431276Abstract: A method for operating a brushless electric motor of a motor vehicle, particularly an electromotive refrigerant compressor, with two sub-motors arranged in sections and each comprising n-phases, by means of a converter corresponding to the number of phases of the electric motor. On the basis of a performance requirement, first switching points are determined for the n-phases, of one of the sub-motors, and on the basis of the performance requirement, second switching points are determined for the n-phases of the other sub-motor. The second switching points are shifted by a first phase angle and the converter is controlled on the basis of the first switching points and the second switching points. The first phase angle is selected such that a resulting current flow over the converter is smaller than a first threshold value. A unit of a motor vehicle, comprising a brushless electric motor is also disclosed.Type: GrantFiled: November 22, 2017Date of Patent: August 30, 2022Assignee: Brose Fahrzeugteile GmbH & Co.

Patent number: 10737554Abstract: A method for operating an electric motor-driven refrigerant compressor of a motor vehicle is provided. A first temperature of a power semiconductor is measured, and a second temperature of the power semiconductor is determined using a theoretical model of the motor-driven refrigerant compressor. A difference between the first temperature and second temperature is determined. A fault is detected if the difference is greater than a first threshold. The invention further relates to a motor-driven refrigerant compressor of a motor vehicle, to the use of a motor-driven refrigerant compressor, and to a motor vehicle comprising a refrigerant circuit.Type: GrantFiled: December 15, 2016Date of Patent: August 11, 2020Assignee: Brose Fahrzeugteile GmbH & Co.

Patent number: 6527427Abstract: A device for setting the distance between a first and a second component, in particular for the horizontal and vertical setting of motor vehicle headlamps, includes a setting screw which is connected to the first component, and which engages the second component. The drive for the setting screw has a slipping clutch that prevents overadjustment of the distance setting device after a maximum torque is reached. The slipping clutch prevents the transmission of torque to the setting screw by slipping, and thereby prevents damage to the distance setting device.Type: GrantFiled: October 14, 2000Date of Patent: March 4, 2003Assignee: Asyst Technologies, LLCInventor: Joachim Schröder
