Method for determination of active resistances, natural and mutual inductances of stator and rotor of asynchronous motors

摘要

Method for determination of active resistances, natural and mutual inductances of stator and rotor of asynchronous motors at which registration of actually acting in asynchronous motor signals one performs in modes of its working functioning with following processing of signals; at that as actually acting in asynchronous motor signals one uses instantaneous values of phase currents for 4 sequential intervals of measurement, instantaneous values of phase or linear voltages for 4 sequential intervals of measurement and frequency of rotation of shaft of machine (one measurement at stable velocity or four – at unstable), and as parameters of asynchronous motors – active resistances of stator and rotor, natural inductances of stator and rotor and mutual inductance of those.
