🔍 Key Concepts

• Brushless alternator construction – how the rotor and stator are arranged and how current is transferred • Difference between mechanical contacts (like brushes) and static/solid‑state components • Role of slip rings and commutators versus electronic excitation systems

💭 Think About

• Ask yourself: in a brushless machine, which parts that normally carry current to a rotating element would be eliminated? • Think about which components on the list are still needed in modern brushless generator systems for controlling output voltage and providing excitation. • Which of the options specifically involve physical contact between moving and stationary parts, and which are electronic or separate machines?

✅ Before You Answer

• Identify which components traditionally require physical sliding contact to transfer current to a rotating rotor. • Confirm which listed devices can be (and usually are) used even in brushless alternator systems (for control and rectification). • Eliminate any choice that is clearly an electronic control or conversion device rather than a mechanical contact device.
