Q

By what means is voltage and current generated by modern revolving field AC generators brought out from the alternator enclosure to the connected switch board?

🔍 Key Concepts

• Construction of a modern AC alternator – which part is stationary vs. rotating • How power is taken off in revolving field (rotating field, stationary armature) machines • The difference between AC output conductors and DC field excitation connections

💭 Think About

• Identify which part of a revolving field alternator actually produces the usable AC output: the rotor or the stator? • Decide whether sliding contacts are needed for the main AC output or only for the DC excitation of the rotating field • Think about which component (slip rings, commutator, collector rings, or direct leads) is normally associated with AC vs. DC machines

✅ Before You Answer

• Verify which element – commutator vs. slip/collector rings – is a feature of DC machines vs. AC alternators • Confirm whether the armature windings in a revolving field alternator are stationary or rotating • Check if the AC output is more reliably taken out through fixed leads from the stationary windings or through brushes and rotating rings
