    • The invention relates to a method for operating an electronically commutated electric machine (2). Alternating phase voltage potentials are applied to the phase conductors of the electric machine (2) for commutation, said phase voltage potentials being generated by a pulse-width modulation so that the height of the applied phase voltage potential is determined by a duty cycle (TV) of the pulse width modulation. In order to determine an instant of a zero crossing of a current induced in a phase conductor, a blanking interval (AT) which represents a time slot, is provided, when no phase current potential is applied to the corresponding phase conductor. A first transition time slot (ÜT1) is provided prior to and/or after the blanking interval (AT) during which the progression of the applied phase voltage potential has a defined first gradient during.

    • A device detecting jamming of electrical drives, especially window lifts and sliding sunroofs provided in vehicles. In order to detect jamming said device uses induced voltage (Uind) in the armature of the engine (1) as a measure of reference. Induced voltage is determined from engine terminal voltage (Ubat) and current (1A) flowing through the armature of the engine (1). Said voltage is determined from the difference between engine terminal voltage and and the product of armature current and armature resistance (RA) which is determined as regularly as possible. Armature resistance is determined from (RA) from engine terminal voltage and engine blocking current (Iblock) which is determined by extrapolation of armature current at a given time (T0). Armature current is measured via a shunt resistor (3) and amplified if necessary (5) . The determined current signal (V1) is averaged with adaptable calculated integration times by means of an integrator (5, 7) controlled by a microcontroller and digitized by means of an analog to digital converter.
