Method for determination of electromagnetic parameters of alternating current machines that is in fact that at fixed rotor of asynchronous motor one applies voltage to windings of stator, with measurement of massif of values of voltage and current, with determination of dependence of total resistance of T-like circuit of replacement on relative frequency, with determination of value of active resistance of stator, one determines sum of inductive resistances of magnetization contours and stator as derivative from total resistance, after that at frequenciesone determines value, active resistance of rotor, inductive resistances of stator, rotorand magnetization contourare determined from system of equations that comprises expressions for dependences of total resistance and derivative of total resistance on frequency: |
