What is the Slip Percentage of a Squirrel Cage Motor at Full-Load?

• A. 1% - 2%
• B. 3% - 5%
• C. 5% - 7%
• D. 0% - 1%

Answer: (B)

The Slip Percentage of a Squirrel Cage Motor at Full-Load typically ranges from 3% to 5%. This value represents the difference between the synchronous speed of the motor's magnetic field and the actual speed of the rotor at full load, expressed as a percentage of the synchronous speed. In practice, most squirrel cage induction motors exhibit a small but measurable amount of slip during operation, particularly under loaded conditions. At full-load, the rotor cannot achieve synchronous speed because of factors such as load demand and motor design characteristics. The typical value of 3% to 5% accounts for these dynamics, ensuring that the motor generates sufficient torque to handle the load while maintaining efficient operation. Understanding the slip percentage is crucial for assessing motor performance, efficiency, and load capabilities, aiding in appropriate motor selection for various applications.
