Abstract: Exemplary methods and systems of determining stall of a fan are disclosed, when the fan is controlled with a frequency converter. The method includes estimating a rotational speed (n) and the torque (T) of the fan. Transferring characteristic curves of the fan to the estimated rotational speed (n) of the fan, determining the stall region of the fan. Determining an operation point of the fan from the estimated rotational speed (n) and estimated torque (T) using the characteristic curves. Calculating RMS values of the low frequency components of the torque and rotational speed estimates (TRMS, nRMS) to obtain a low frequency parameter (S), and determining an occurrence of stall based on at least one of the operation point and the low frequency parameter (S).
