Frequency given Number of Poles in Induction Motor Solution

Follow our step by step solution on how to calculate Frequency given Number of Poles in Induction Motor?

FIRST Step Consider the formula

f = \frac{n \cdot N s}{120}

Next Step Substitute values of Variables

∴

f = \frac{4 \cdot 15660rev/min}{120}

Next Step Convert Units

∴

f = \frac{4 \cdot 1639.9114rad/s}{120}

Next Step Prepare to Evaluate

∴

f = \frac{4 \cdot 1639.9114}{120}

Next Step Evaluate

∴

f = 54.6637121696787Hz

LAST Step Rounding Answer

∴

f = 54.6637Hz
