3-ϕ ఇండక్షన్ మోటారులో, స్టేటర్ యొక్క అయస్కాంత క్షేత్రం సమకాలిక వేగంతో తిరుగుతుంది.
అలాగే, \({N_S} = \frac{{120f}}{P}\)
ఇక్కడ,
NS = rpmలో సమకాలిక వేగం
f = Hzలో సరఫరా పౌన:పున్యం
P = ధ్రువాల సంఖ్య
గణన:
స్టేటర్ యొక్క అయస్కాంత క్షేత్రం NS వద్ద తిరుగుతుంది
∴ \({N_S} = \frac{{120 \times 50}}{4} = 1500\;rpm\)
