Abstract

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. Likewise, a converter circuit and a laundry appliance perform the method and have a converter circuit for controlling a polyphase dynamo-electrical machine, which, in particular, drives a drum which is mounted in the laundry appliance such that it can rotate.
