The technology has improved amazingly in recent years, allowing (among other things) motors of amusing compactness. Excitation coils become history. Moreover ISTR that some alternators generate their own excitation current from power they produce, via an in-built rectifier. All that's needed to start the process is the residual magnetism from the last time it ran; then the alternator "boots" itself, feeding power back to build a field until everything's at full strength. -- Andrew Stephenson
