Abstract
Способ диагностирования обмоток электрических машин постоянного тока, заключающийся в пропускании электрического тока через обмотку, в сравнении сопротивления обмотки с эталонным сопротивлением и в определении работоспособности обмотки по результатам сравнения, отличающийся тем, что через обмотку пропускают переменный ток с частотой больше частоты оборотов якоря электрической машины и больше граничной частоты f=(60/2π)R/L, где R - сопротивление обмотки по постоянному току, L - индуктивность обмотки.A method for diagnosing windings of electric DC machines, which consists in passing an electric current through the winding, in comparing the resistance of the winding with the reference resistance and in determining the operability of the winding according to the comparison results, characterized in that alternating current is passed through the winding at a frequency higher than the speed of the armature of the electric machine and greater than the cutoff frequency f = (60 / 2π) R / L, where R is the DC resistance of the winding, L is the winding inductance.
