Patent number: 9096964Abstract: In a method for determining a load and/or an unbalance of a laundry drum of a washing machine driven by an electric motor having a stator with at least one winding coupled to a power inverter controlled by a control unit, the laundry drum is accelerated to a predetermined rotational speed and then slowed down. During the slow-down, the motor operates in generator mode and an electric current flowing through the at least one winding and/or an electric intermediate circuit voltage is measured. The time dependence of the electric power supplied by the electric motor in generator mode is evaluated during a revolution of the laundry drum. The unbalance and/or the load are determined from the measured current values and/or the intermediate circuit voltage and from the determined electric power. A corresponding circuit arrangement and a washing machine with this circuit arrangement are also disclosed.Type: GrantFiled: February 18, 2010Date of Patent: August 4, 2015Assignee: BSH Hausgeräte GmbHInventors: Hasan Gökcer Albayrak, Torsten Böttger, Jörg Skrippek

Patent number: 7372233Abstract: A method is provided for operating a converter circuit, in particular a pulse-width modulated frequency converter circuit having a DC voltage intermediate circuit, which controls two or more winding sections of a polyphase dynamo-electrical machine, in particular a three-phase asynchronous motor for a laundry appliance. The method determines one or more parameters of the dynamo-electrical machine, before a rotating field is produced in the dynamo-electrical machine by the converter circuit. The parameters can be used to deduce a variant of the dynamo-electrical machine, and to select open-loop and closed-loop control parameters which are associated with the variant. Likewise, the method allows possible machine faults to be determined by using the parameters.Type: GrantFiled: June 1, 2004Date of Patent: May 13, 2008Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Hasan Gökcer Albayrak, Lothar Knopp, Thomas Ludenia, Jörg Skrippek

Patent number: 6374444Abstract: A method and appliance for determining the angular position of a laundry drum and a power consumption of an electric motor driving the drum to derive therefrom a laundry weight in the drum includes directly driving the drum with the motor from a lower laundry position to a raised position where a laundry center of gravity is offset from a rotation axis to produce a loading weight from the driving current of the electric motor measured when the raised position is reached. Alternatively or additionally, the drum is turned until the controller detects a power consumption of the electric motor corresponding to a stored maximum current value to derive a weight of the laundry from a signal corresponding to the angular distance. The controller stores a predetermined, defined maximum current value and measures a power consumption of the electric motor.Type: GrantFiled: January 10, 2001Date of Patent: April 23, 2002Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Jörg Skrippek, Reinhard Heyder
