Abstract
The advantages of electric energy have led to changes in the structure of conventional airplanes and the creation of new structures called more-electric or all-electric airplanes. In these applications, reducing the number of parts and thus the weight of the system will lead to increased efficiency and transportation distance, reducing energy consumption and increasing reliability. In this regard, the motor that is used to start the aircraft engine is integrated with the generator and is used in the form of an electric machine called starter-generator. In this article, while studying different starter-generator structures in aerospace applications, the PM synchronous machine is selected, the equations related to the PM synchronous starter-generator design are extracted and a starter-generator with a nominal power of 6 kW is designed and analyzed using Maxwell finite element software.
In order to create structural strength at high speeds (generator mode) and soft start in motor mode, the use of carbon fiber around the rotor magnets and also the skewing for the stator sluts is suggested. Finally, based on the finite element method, the performance of the designed machine has been evaluated in start-up, no-load and generator modes, and thermal analysis has also been carried out. The results show the proper performance of the machine in the mentioned application.
