摘要： A method ascertains current-dependent inductances of a polyphase electrical machine. The method generates phase voltages for the polyphase electrical machine by means of a pulse width modulation such that currents of predefined current level flow through stator windings of the electrical machine. During a number of cycles of the pulse width modulation, the method generates a voltage pulse such that a change of current is brought about in a torque-forming axis of the polyphase electrical machine and/or in a field-forming axis of the polyphase electrical machine. The method measures the change of current, and ascertains the current-dependent inductances on the basis of the change of current.

摘要： The invention relates to a method for configuring a drive system for a technical device, wherein: the technical device consists of at least one module; the drive system is composed of a plurality of components; the components of the drive system are selected from a large number of possible component types; each selectable component type is allocated a component type data object in a data storage device, said component type data object containing component type data about the properties, more particularly the technical properties, of the component type. In a data storage device, module type data objects are stored that are allocated to module types, wherein the module type data objects contain module type data about the properties, more particularly the technical properties, of the module types. First, the module type of the at least one module which makes up the technical device is selected by a user via a user interface, and then a module data object allocated to the module is generated by means of a data processing device, said module data object containing module data about the properties, more particularly the technical properties, of the module type of the at least one module, and, on the basis of the module data, the component type of at least one component of the drive system is selected.
