Abstract

Sposób diagnozowania drgań wzbudzanych niewywagą w maszynach elektrycznych (1) z magnesami trwałymi, o liczbie par biegunów p i pracujących z prędkością obrotową n, obejmuje rejestrację, układem pomiarowym (7), przebiegu napięcia lub prądu diagnozowanej maszyny, wykonanie analizy częstotliwościowej zarejestrowanego napięcia lub prądu, a następnie wydzielenie częstotliwości f1 = (p - 1)n/60 i f2 = (p + 1)n/60). Sposób diagnozowania drgań wykonuje się także, poprzez wydzielenie częstotliwości f1 i f2 z zarejestrowanego przebiegu napięcia na dławiku (8) włączonym w obwód uzwojenia maszyny badanej (1).The method of diagnosing vibrations induced by unbalance in electric machines (1) with permanent magnets, with the number of pairs of poles pi operating at rotational speed n, includes recording, measuring system (7), voltage or current of the diagnosed machine, frequency analysis of the recorded voltage or current, and then separating the frequency f1 = (p - 1) n / 60 and f2 = (p + 1) n / 60). The method of diagnosing vibrations is also performed by separating the frequencies f1 and f2 from the recorded voltage waveform on the choke (8) connected to the winding circuit of the tested machine (1).
