Question 1 of 27070

In a basic AC induction motor, by what means is current induced in the rotor?

🔍 Key Concepts

• Induction in an AC induction motor (no direct electrical connection to rotor windings) • Role of the stator’s rotating magnetic field in creating rotor current • Difference between motors that use brushes/commutators and those that don’t

💭 Think About

• Ask yourself: In an induction motor, does the rotor usually receive power by wires and contacts, or without physical electrical contact? • Which choice describes a process where a changing magnetic field can create current in nearby conductors? • Which options clearly belong to DC or controlled circuits rather than a simple, basic AC induction motor design?

✅ Before You Answer

• Verify which device uses brushes and armature (AC induction vs DC motor or wound-rotor designs). • Check that the method you choose involves no direct electrical connection to the rotor windings in a squirrel-cage induction motor. • Eliminate any options that are mainly used for DC conversion or external rotor control rather than the fundamental induction process.
