No Load Speed of Shunt DC Motor Solution

Follow our step by step solution on how to calculate No Load Speed of Shunt DC Motor?

FIRST Step Consider the formula

N nl = \frac{N reg \cdot N fl}{100 + N fl}

Next Step Substitute values of Variables

∴

N nl = \frac{12012rev/min \cdot 0.19rev/min}{100 + 0.19rev/min}

Next Step Convert Units

∴

N nl = \frac{1257.8937rad/s \cdot 0.0199rad/s}{100 + 0.0199rad/s}

Next Step Prepare to Evaluate

∴

N nl = \frac{1257.8937 \cdot 0.0199}{100 + 0.0199}

Next Step Evaluate

∴

N nl = 0.250230220423533rad/s

Next Step Convert to Output's Unit

∴

N nl = 2.38952258960447rev/min

LAST Step Rounding Answer

∴

N nl = 2.3895rev/min
