An arrangement having an electric motor ( ) has a microcontroller ( ) for influencing at least one motor function and a nonvolatile storage element ( ) for storing at least one variable as a definition for that motor function. The arrangement also has an interface ( ) for a data line ( ) for transferring the at least one variable, in particular a current limiting value (I ) from or to a storage element ( ) by way of the microcontroller ( ), and optionally by way of an internal data bus ( ). 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 ( ).

Device with an electromotor

The rotation speed of an electric motor ( ) is controlled by a controller ( ) which receives its setpoint from a characteristic function ( ). The characteristic function ( ) calculates a setpoint for the controller ( ) on the basis of an originally analog variable A ( ) that is converted to digital by an A/D converter AD ( ), with the aid of support values of a &ldquo;MEM&plus;DATA&rdquo; characteristic that are stored in a memory ( ); those values not predefined by the support values are calculated by interpolation.
