Claims (2)

1. Способ диагностики механизмов и систем с электрическим двигателем, заключающийся в том, что измеряют частоты амплитудной модуляции потребляемого электрическим двигателем электрического тока и для каждой частоты модуляции измеряют глубину амплитудной модуляции тока, по измеренной частоте модуляции определяют дефектный агрегат механизма или системы, вызывающий появление переменной нагрузки на электрический двигатель, а по измеренной глубине модуляции определяют величину этого дефекта.1. A method for diagnosing mechanisms and systems with an electric motor, which consists in measuring the frequency of the amplitude modulation of the electric current consumed by the electric motor and for each modulation frequency, measuring the depth of the amplitude modulating current, using the measured modulation frequency, determining the defective aggregate of the mechanism or system that causes the appearance of a variable loads on the electric motor, and the magnitude of this defect is determined by the measured modulation depth. 2. Способ по п.1, отличающийся тем, что предварительно создают перечень характерных частот вращения или перемещения агрегатов механизма или системы, а также их отдельных элементов.2. The method according to claim 1, characterized in that pre-create a list of characteristic frequencies of rotation or movement of the aggregates of the mechanism or system, as well as their individual elements.
