Summary on Grant Application Form
Preliminary analytical and experimental work at UMIST has demostrated that an isolate permanent magnet alternator with interior-type rotor can produce negative voltage regulation when feeding a resistive load and that this unusual performance is a function of inverse saliency. The proposed project aims to demonstrate the scope for exploitation of this phenomenon, by analysis and practical tests. A typical target performance would be zero voltage regulation when supplying rated load, with generally low regulation at other loads. Demonstrator machines will be designed, constructed, tested and evaluated. Optimum design criteria will be developed and attainable performance levels presented.
