<p>An electric motor movement controlling method, the electric motor being fed by a total voltage (VT) proportional to the network voltage (VAC), the method comprising steps of making a first measurement of level (Vt10) of the network voltage (VAC) at a first moment of measurement (t1 0), Making a second measurement of level (Vt20) of the network voltage (VAC) At a second moment of measurement (t2 0), calculating the value of the derivative of the values of voltage measured in function of the first and second moments of measurement (t10, t20), to obtain a value of a propor-tional network voltage (VAC'), and altering the value of the total voltage (VT) fed to the motor, proportionally to the value of the proportional network (VAC'). A system that will implement the steps of the method of the present invention, as well as a compressor (14) comprising the system of the present invention are foreseen.</p> |
