Q

What term represents the difference between synchronous speed and actual speed of a running AC induction motor?

🔍 Key Concepts

• Synchronous speed vs. actual rotor speed in an AC induction motor • How torque is produced in an induction motor (needs a speed difference) • Standard electrical engineering term for this speed difference

💭 Think About

• Which of these options is a well-known technical term used in motor theory textbooks for the speed difference between the rotating magnetic field and the rotor? • Think about what allows current to be induced in the rotor—does the rotor need to be exactly at synchronous speed or slightly behind it? What is that condition called? • Eliminate any answer choices that are generic English words but not standard motor-technology terminology.

✅ Before You Answer

• Verify which term you’ve seen specifically defined as the difference between synchronous speed and rotor speed in AC machines • Check which options are commonly used in induction motor performance calculations and efficiency discussions • Be sure the term you pick is not mainly used for compass errors or unrelated navigation concepts
