Abstract

The present invention relates to a method of determining with the aid of an asynchronous electric motor the actual torque that is required to start-up and run a plant (1) that is driven by the electric motor (2). The method is characterized by measuring motor speed, voltage and current, and the phase angle between current and voltage, and comparing the measurement values obtained with known and mapped motor performance values, to establish the torque actually required with regard to the plant (1). The invention also relates to the use of the method.
