摘要: The invention relates to a method for detecting sluggishness or blockage of an electric drive (3), which is controlled by means first power semiconductor component (7). (3) can be operated both in the part-load range (pulse width modulation (PWM) timing signal < 100%) and full load (PWM = 100%), ranges being dependent on PWM (29, 30). An evaluation circuit (37) connected microcontroller (25). Pulses that are generated within time detected current flows over element (7) number pulses A1*, A2* compared with expected A1, A2.
