1. Gas turbine and compressed air systems will serve as prime movers at a very high speed. Discuss the design characteristics of an induction generator for those applications.
2. Explain in detail why induction generators of the same rating as synchronous generators are larger.
3. What are the differences between a high standard induction generator and the corresponding induction motor?
4. Research about the mining, manufacturing, and production of permanent magnets, which countries produce, and the ones that import them. Compare the economics and sustainability of permanent magnet-based machines versus induction generators.
