Slip Rate Formula
The following two example problems outline the steps and information needed to calculate the Slip Rate.
SR = (Ns - N) / Ns*100
Variables:
- SR is the Slip Rate (%)
- Ns is the synchronous speed (RPM)
- N is the rotational speed (RPM)
To calculate the slip rate, divide the difference between the synchronous speed and the rotational speed by the synchronous speed.
How to Calculate Slip Rate?
The following steps outline how to calculate the Slip Rate.
- First, determine the synchronous speed (RPM).
- Next, determine the rotational speed (RPM).
- Next, gather the formula from above = SR = (Ns – N) / Ns*100.
- Finally, calculate the Slip Rate.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
synchronous speed (RPM) = 500
rotational speed (RPM) = 400
SR = (Ns – N) / Ns*100 = ?
