Motor Slip Calculator
Calculate the slip percentage for induction motors with our comprehensive calculator. Determine motor efficiency, performance issues, and optimal operating conditions.
Step 1: Motor Specifications
Understanding Motor Slip
Slip is the difference between synchronous speed and actual rotor speed in induction motors. Normal slip is typically 2-5% for standard motors. Higher slip may indicate motor issues or overload.
Step 2: Calculations & Results
About Synchronous Speed
Synchronous speed is calculated as: (120 × Frequency) ÷ Number of Poles. This is the theoretical speed of the rotating magnetic field in the stator. Actual rotor speed is always slightly less due to slip.

Slip Calculation Formula
Slip (%) = ((Synchronous Speed – Actual Speed) / Synchronous Speed) × 100
To calculate motor slip: First calculate synchronous speed (120 × Frequency ÷ Poles), subtract actual rotor speed, divide by synchronous speed, then multiply by 100 to get percentage.
