🔍 Key Concepts

• Synchronous speed formula for AC induction motors • Relationship between frequency, number of poles, and motor speed • Difference between factors that affect torque/slip vs those that set the basic synchronous speed

💭 Think About

• Think about which part of the motor’s design sets how many times the magnetic field rotates per second for a given supply frequency. • Ask yourself: which option directly changes the magnetic field cycle count in the stator, instead of just losses or heating in the rotor? • Consider the basic formula used to calculate the approximate speed of an induction motor—what design parameter appears in that formula along with frequency?

✅ Before You Answer

• Recall or look up the synchronous speed formula: it involves frequency and one key design parameter. • Eliminate choices that mainly affect losses, torque, or slip rather than the fundamental rotating field speed. • Verify which component (stator vs rotor) determines how many magnetic poles are present in the rotating field.
