🔍 Key Concepts

• Construction of different motor rotors (squirrel cage vs wound rotor vs DC commutator) • How current is supplied to the rotating part (rotor) in AC and DC motors • Difference between brush-type and brushless motor designs

💭 Think About

• For each option, ask: does the rotor need a separate electrical connection (slip rings or commutator) for it to work? • Think about which motors use brushes or slip rings to get power into the rotor, and which use only electromagnetic induction. • Which motor type is commonly known for having a simple, rugged rotor with bars and end rings, requiring no electrical contact to it?

✅ Before You Answer

• Identify which listed motors have a commutator and brushes (typical of DC motors). • Identify which listed AC motors use slip rings to feed the rotor (typical of wound rotors or certain synchronous motors). • Confirm which motor type has a rotor with no external electrical connection at all, relying purely on induction.
