The Concept of Developing and Implementing an Integrated Aircraft Generator with an External Rotor

The use of a generator with an external rotor, as opposed to the classic version of a generator with an internal rotor with the same dimensions, makes it possible to increase the specific indicators from 10 to 34% and to obtain a specific power of about 3.87 kW/kg compared with 2.56 kW/kg for a generator with an internal rotor. By increasing the area of the external rotor, the heat transfer can be increased, thereby maintaining the operating temperature range of the permanent magnets and ensuring the operability of the entire system as a whole. It is shown that the existing technological experience makes it possible to implement the idea of integrating an aircraft generator into an aircraft engine. The assembly technology of the generator with an external rotor is presented in detail.
