\({N_s} = \frac{{120f}}{P}\)

f Hz या C/s में आवृत्ति है

P ध्रुवों की संख्या है

प्रेरण मोटर तुल्यकालिक गति के निकटतम लेकिन उससे कम गति (Nr) पर घूमता है।

प्रेरण मोटर की सर्पी इसके द्वारा दी जाती है,

\(s = \frac{{{N_s} - {N_r}}}{{{N_s}}}\)

जहाँ Ns तुल्यकालिक गति है

और Nr रोटर की गति है

अवलोकन:

उपरोक्त अभिव्यक्ति से एक प्रेरण मोटर की गति आपूर्ति आवृत्ति और ध्रुवों की संख्या पर निर्भर करती है।
