Method of diagnostics of the short-circuited rotor damage on point induction converters

摘要

A method has been developed for diagnostics of the short-circuited rotor damage of asynchronous motor by external magnetic field. The information sign is a change in amplitude of harmonic components of this field measured with the help of point induction converters. A method for determining the sliding of an asynchronous motor by an external magnetic field is proposed.
