The results of the production tests of the method for diagnosing the eccentricity of the rotor of an asynchronous electric motor

Ensuring the reliability of electrical equipment in agriculture remains an urgent problem, since rugged operating conditions and aggressive environment hinder its rational use. The high accident incidence rate asynchronous motors most cases is invariably caused by failure inter-turn insulation interphase short circuit or circuits to housing. probability emergency situation increases with increase radial clearance bearings and, consequently, occurrence static eccentricity rotor. developed method for diagnosing rotor motor based on analysis speed; amplitude speed change was used as a diagnostic parameter. paper presents rotation frequency depending difference amplitudes, resulted from study conducted different values eccentricity. test results have shown that rotor, fluctuations increases.
