A method for detecting stalling of an electric stepper motor (18) is provided. The method includes a) collecting samples of the voltage at a coil of the stepper motor (18) continuously or in regular intervals, b) determining a deviation value corresponding to the deviation between the measured voltages of the two samples, and c) determining whether the electric motor (18) is stalling by utilizingthe deviation value. Further, the stepper motor and a heating, ventilation and/or air conditioning system are provided. 示出了种用于检测电动步进马达(18)的停转的方法，具有以下步骤：a)连续地或以规则的间隔采集所述步进马达(18)的线圈处的电压的样本，b)对应于所述两个样本的测量电压之间的偏差来确定偏差值，以及c)使用所述偏差值来确定所述电动马达(18)是否停转。还示出了种步进马达和种加热、通风和/或空调系统。
