identificare motor electric

Recommended Posts

In gol turatia este foarte mare dar scade rapid cu sarcina.

Turatia la sarcina nominala cred ca e in jur de 2400rpm.

Se poate calcula mai precis daca stiti/masurati rezistenta + inductanta infasurarii si curentul + turatia in gol.

Pentru polizor e mai potrivit un motor cu rotorul în scurtcircuit, acelea au turaţia în gol limitată constructiv.Cu turaţie foarte mare nu poţi folosi direct decât pietre abrazive mici, la polizoare gen ,,dremel,,.
