Slip of Motor in Induction Motor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Slip = (Synchronous Speed-Motor Speed)/Synchronous Speed
s = (N_s-N_m)/N_s
This formula uses 3 Variables

Variables Used

Slip - Slip in Induction Motor is the relative speed between the rotating magnetic flux and rotor expressed in terms of per unit synchronous speed. It is a dimensionless quantity.
Synchronous Speed - (Measured in Radian per Second) - Synchronous speed is a definite speed for an alternating-current machine that is dependent on the frequency of the supply circuit.
Motor Speed - (Measured in Radian per Second) - Motor Speed is the speed of the rotor(motor).

STEP 1: Convert Input(s) to Base Unit

Synchronous Speed: 15660 Revolution per Minute --> 1639.91136509036 Radian per Second (Check conversion here)
Motor Speed: 14350 Revolution per Minute --> 1502.72848589059 Radian per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

s = (N_s-N_m)/N_s --> (1639.91136509036-1502.72848589059)/1639.91136509036

Evaluating ... ...

s = 0.0836526181353778

STEP 3: Convert Result to Output's Unit

0.0836526181353778 --> No Conversion Required

FINAL ANSWER

0.0836526181353778 ≈ 0.083653 <-- Slip
