In a three-phase, squirrel-cage type, induction motor, how is the primary rotating magnetic field established?

🔍 Key Concepts

• Stator vs. rotor roles in an induction motor • How a three-phase AC supply creates a rotating magnetic field • Difference between what creates the rotating field and what reacts to it

💭 Think About

• Ask yourself: Which part of the motor is connected directly to the three‑phase power source, stator or rotor? • Which component’s magnetic field must exist FIRST so that current can be induced in the other? • Which choice describes the CAUSE of the rotating field, and which describe EFFECTS that happen AFTER the field is already present?

✅ Before You Answer

• Identify which option clearly involves the three separate phase windings spaced 120 electrical degrees apart. • Separate answers that describe the creation of the rotating stator field from those that describe induced currents or mechanical construction of the rotor. • Verify that the option you pick describes something that happens before any rotor current is induced.
