Abstract (en)

[origin: DE102004057869A1] A motor control device (12) uses operating switch processes to switch connection methods (14) so that phase currents are fed from time to time to an electric motor (10) so as to operate the motor. A connection method (14) carries out a test switch process for determining a phase current. An independent claim is also included for a device for determining a phase current in an electric motor, e.g. for a motor vehicle.
