Motor Speed in Induction Motor Solution

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

FIRST Step Consider the formula

N m = N s \cdot (1 - s)

Next Step Substitute values of Variables

∴

N m = 15660rev/min \cdot (1 - 0.19)

Next Step Convert Units

∴

N m = 1639.9114rad/s \cdot (1 - 0.19)

Next Step Prepare to Evaluate

∴

N m = 1639.9114 \cdot (1 - 0.19)

Next Step Evaluate

∴

N m = 1328.32820572319rad/s

LAST Step Convert to Output's Unit

∴

N m = 12684.6rev/min
