Here is how the Slip of Motor in Induction Motor equation looks like.

0.0837 = \frac{15660 - 14350}{15660}

0.0837 = \frac{15660rev/min - 14350rev/min}{15660rev/min}

0.0837 = \frac{15660 - 14350}{15660}

Slip of Motor in Induction Motor Solution

Follow our step by step solution on how to calculate Slip of Motor in Induction Motor?

FIRST Step Consider the formula

s = \frac{N s - N m}{N s}

Next Step Substitute values of Variables

∴

s = \frac{15660rev/min - 14350rev/min}{15660rev/min}

Next Step Convert Units

∴

s = \frac{1639.9114rad/s - 1502.7285rad/s}{1639.9114rad/s}

Next Step Prepare to Evaluate

∴

s = \frac{1639.9114 - 1502.7285}{1639.9114}

Next Step Evaluate

∴

s = 0.0836526181353778

LAST Step Rounding Answer

∴

s = 0.0837
