Abstract
This paper presents the results of an investigation of an intelligent starter–generator (SG) with a capacity of 16 kV A and rotation frequency of 12000 rpm. In designing the SG, a multidisciplinary approach was used in which all the calculations of an electrical machine were interdependent and had the form of a symbiosis of electromagnetic, thermal, and mechanical calculations concerning the rotor dynamics. Interrelated optimization problems were simultaneously solved during such calculations using genetic algorithms. Such an approach provides maximum accuracy, especially when designing highly loaded electrical machines, where even an insignificant change of any parameter can lead to a considerable change in the structural diagram of the SG and its dimensions. The experimental model of the SG was tested in the full-power regime and at rated speed. The measurement results of the output voltage and heating temperature of the active elements correspond to the design ones. The deviation from the design voltage data was 1.7%. This small error confirms the efficiency of the multidisciplinary design methods used. Based on the test results, a comparison with the characteristics of aircraft generators of similar power is carried out and the developed SG is shown to be efficient.
