No Load Speed of Shunt DC Motor Solution

STEP 0: Pre-Calculation Summary

Formula Used

No Load Speed = (Speed Regulation*Full Load Speed)/(100+Full Load Speed)
N_nl = (N_reg*N_fl)/(100+N_fl)
This formula uses 3 Variables

Variables Used

No Load Speed - (Measured in Radian per Second) - No Load Speed is defined as a reference to how fast the shaft of a motor will turn before weight is added to it.
Speed Regulation - (Measured in Radian per Second) - Speed Regulation is the change in speed from no load to full load, expressed as a fraction or percentage of full load speed.
Full Load Speed - (Measured in Radian per Second) - Full Load Speed is defined as the speed of the motor at which the motor is fully loaded to provide its maximum torque to drive the load.

STEP 1: Convert Input(s) to Base Unit

Speed Regulation: 12012 Revolution per Minute --> 1257.8936984333 Radian per Second (Check conversion here)
Full Load Speed: 0.19 Revolution per Minute --> 0.0198967534717222 Radian per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_nl = (N_reg*N_fl)/(100+N_fl) --> (1257.8936984333*0.0198967534717222)/(100+0.0198967534717222)

Evaluating ... ...

N_nl = 0.250230220423533

STEP 3: Convert Result to Output's Unit

0.250230220423533 Radian per Second -->2.38952258960447 Revolution per Minute (Check conversion here)

FINAL ANSWER

2.38952258960447 ≈ 2.389523 Revolution per Minute <-- No Load Speed

(Calculation completed in 00.004 seconds)
