Method for measuring a motor current

The Invention relates to a method for measuring a by a motor (1) the current flowing (IMOT), Wherein a motor (1) with electrical Energizing the power switching section (2) by means of a control unit (4) a pulse width modulation signal (10) is controlled, wherein the Pulse-width modulation signal (10) has a switching cycle (15), and wherein the motor current (IMOT) in a Supply line (8, 8a) for the power switching section (2) or in a feed line (9, 9a) is determined to the motor (1). By per switching cycle (15) exactly one motor current (IMOT) Representing Measuring value is sampled, a method for measuring the motor current (IMOT) Indicated that cost-effective and faster the motor current (IMOTdetermined) as is the case in the prior art. The process takes Application in the motor control for DC motors.
