Patent number: 9476430Abstract: The disclosure relates to a method for operating a positioning actuator system with an electronically commutated actuator drive for driving an actuator element, having the following steps: non-volatile storage of a position information item of the actuator element or of a rotor of the actuator drive which was detected last as a reference position before the positioning actuator system is switched off; in the case of switching on of the positioning actuator system retrieval of the reference position and actuation of the actuator drive by energizing the actuator drive in accordance with a space phasor which is dependent on the reference position. The object is to make available an improved method for releasing blockage of an actuator element or actuation after activation of a motor system with a maximum actuating torque. For positioning actuators with commutated motors such as, for example, synchronous motors.Type: GrantFiled: January 4, 2012Date of Patent: October 25, 2016Assignee: Robert Bosch GmbHInventors: Ingo Immendoerfer, Alex Grossmann, Udo Sieber, Ralf Buehrle, Zeynep Tosun

Patent number: 7927113Abstract: Electric fuel pumps are already known with a pump housing and a ground terminal, which is provided on a terminal cover, for making contact with an electrical ground, in which the pump housing and the ground terminal are connected to one another via a ground connection, which has a first contact section for making contact with the pump housing and a second contact section for making contact with the ground terminal. The first contact section is provided on the outer circumference of a terminal cover and, after installation, is pressed with a contact pressure against the inner face of the pump housing. Since the inner face of the pump housing has increasingly been provided with an electrically insulating anticorrosion coating, however, when the terminal cover is pressed into the pump housing, touching contact with the pump housing does take place which is usually also electrically conductive, but as a result of the electrically insulating coating has a high electrical resistance.Type: GrantFiled: September 20, 2007Date of Patent: April 19, 2011Assignee: Robert Bosch GmbHInventors: Pascal Chaumet, Detlef Marth, Erich Jahrstorfer, Ingo Immendoerfer, Philip De Haan, Bruno Schoener

Patent number: 7263832Abstract: The invention is directed to a method and an arrangement (10) for controlling an electrically operated charger (1), which essentially prevent a sudden drop in voltage with the run-up of the electric charger. A drive signal (AS) is formed, which drives the electric charger (1). The rate of change of speed for an increase of the rpm of the electric charger (1) is pregiven in dependence upon the instantaneous supply voltage (UV).Type: GrantFiled: January 31, 2003Date of Patent: September 4, 2007Assignee: Robert Bosch GmbHInventors: Michael Nau, Ingo Immendoerfer, Martin-Peter Bolz, Michael Baeuerle, Carsten Reisinger, Guido Porten

Patent number: 7027315Abstract: A circuit arrangement for operating an electrical machine having an inductive component. The circuit arrangement includes an electrical switch (TR1 through TR6) that applies a pulse-shaped signal (S1 through S4) to the electrical machine. The free-running circuit also includes an electrical switch (TR1 through TR6). A comparator (15) is provided which compares the free-running current flowing in the free-running circuit with a predefined threshold value and, if the current drops below the threshold value, provides a switching signal (S3A) that is used to deactivate the switch (TR1 through TR6) in the free-running circuit. The circuit arrangement reduces both the electrical power loss in the circuit arrangement and the mechanical power loss in the electrical machine.Type: GrantFiled: June 28, 2002Date of Patent: April 11, 2006Assignee: Robert Bosh GmbHInventors: Juergen Halfmann, Ingo Immendoerfer
