🔍 Key Concepts

• Synchronous speed vs. actual rotor speed in an induction motor • Definition of slip as a percentage of synchronous speed • How to convert a slip percentage into an RPM difference

💭 Think About

• First, think about what 4% slip physically means in terms of how much slower the rotor turns than synchronous speed. • Set up a simple percentage calculation using the given synchronous speed (1800 RPM) and the slip (4%). What is 4% of 1800? • Once you know how many RPM represent 4% slip, consider whether you should add or subtract that value from the synchronous speed to get the full-load speed.

✅ Before You Answer

• Be sure you are using 1800 RPM as the base speed when applying the 4% slip. • Confirm whether slip means the rotor runs slower or faster than synchronous speed in an induction motor. • Double-check your final RPM against the choices to ensure it is less than synchronous speed but not by an unrealistically large amount.
