The present disclosure relates to a method of monitoring an electric motor serving to drive a pump, wherein, within a time interval T, current values are measured, an average value of the current values measured is determined and this average value is compared to a predetermined reference value. According to the disclosure, it is provided that the method extends to controlling the electric motor, wherein the current values measured reflect the profile of the winding current of the electric motor and, irrespective of whether they can be associated with an instantaneous maximum value of the current profile, are included in determining the average value, and wherein the average value is considered by the motor control as input parameter.
