Abstract

An arrangement having an electric motor (10) has a microcontroller (12) for influencing at least one motor function and a nonvolatile storage element (14) for storing at least one variable as a definition for that motor function. The arrangement also has an interface (13a) for a data line (13) for transferring the at least one variable, in particular a current limiting value (Iref) from or to a storage element (14) by way of the microcontroller (12), and optionally by way of an internal data bus (15). The invention also relates to use of the device in the context of batteries of fans, and program-controlled current limitation for startup of an electric motor (10).
