Abstract

Способ диагностики межвитковых замыканий асинхронного электродвигателя, включающий измерение ЭДС обмотки электродвигателя при вращении вала по инерции после отключения питающего напряжения, отличающийся тем, что дополнительно измеряют частоту колебаний ЭДС, сравнивают эти значения со значениями, измеренными на исправном электродвигателе, и по результатам сравнения делают вывод о наличии межвитковых замыканий.A method for diagnosing turn-to-turn closures of an asynchronous electric motor, including measuring the EMF of an electric motor winding when the shaft rotates by inertia after disconnecting the supply voltage, characterized in that the frequency of EMF oscillations is additionally measured, these values are compared with the values measured on a serviceable electric motor, and based on the comparison results, a conclusion is made about the presence of turn-to-turn closures.
