Robbins, B., Yost, K., and Zumberge, J., "Experimental Characterization of Brushless Synchronous Machines for Efficient Model-Base System Engineering," SAE Technical Paper 2016-01-2027, 2016, doi:10.4271/2016-01-2027.
Detailed machine models are, and will continue to be, a critical component of both the design and validation processes for engineering future aircraft, which will undoubtedly continue to push the boundaries for the demand of electric power. This paper presents a survey of experimental testing procedures for typical synchronous machines that are applied to brushless synchronous machines with rotating rectifiers to characterize their operational impedances. The relevance and limitations of these procedures are discussed, which include steady-state drive stand tests, sudden short-circuit transient (SSC) tests, and standstill frequency response (SSFR) tests. Then, results captured in laboratory of the aforementioned tests are presented.
