Patent number: 11239782Abstract: A method with which stalling of a rotor of a sensor-free motor can be detected is described below. According to one exemplary embodiment, the method comprises operating an electric motor, wherein a rotation speed of the electric motor is controlled by field-oriented control, and wherein an estimate is calculated, wherein the estimate represents magnetic flux in the electric motor. The method further comprises calculating a value which represents the change in the magnitude of the estimate for the magnetic flux and comparing the calculated value with a threshold value in order to detect whether the calculated value lies below the threshold value.
