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

If a motor becomes defective, e.g. stops running, runs too slowly, or becomes too hot, many customers demand the generation of an alarm signal, i.e. ask for an alarm device provided on the motor. The following method is used for configuring this alarm signal: At least one parameter for configuring the alarm device of the motor is inputted via a input interface (); the at least one parameter is stored in a parameter memory (); the execution of at least one routine of the alarm device provided in the microprocessor () is influenced by said stored parameter or by a parameter derived therefrom. The invention furthermore concerns a motor for carrying out such a method. In a motor of this kind, the alarm device can easily be configured in accordance with a customer's present needs.

Method for configuring the alarm device of an electrical motor and motor for implementing said method

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.
