| Popis: | To meet the growing demand for electric power on board of an aircraft, a need arises to construct powerful generators that have low mass, high power performance characteristics and mechanical strength. It is expected that by furnishing an aircraft with more electricity it will be possible to obtain numerous advantages, including lower costs for aircraft operation and maintenance [3]. The most promising way of achieving this is to use synchronous generators with electromagnetic excitation. However, the development of such machines involves serious difficulties stemming from lack of well-matured methods for analyzing synchronous generators with a floating rotation frequency for capacities above 250 kVA. The article describes an approach to elaborating a comprehensive technique for designing high-capacity aircraft synchronous generators that takes into account both structural strength matters and electromagnetic and thermal processes. The results from modeling the structural arrangement of a nonsalient-pole synchronous generator with a reduced number of inductor teeth are also given. Such generator provides the nominal power output equal to 250 kVA in the entire range of its rotation frequencies from 7200 to 6000 min-1. |
