Estimation of the domestic materials application possibility in the active part of a high-speed electric generator for micro-GTP

Abstract

The article discusses the possibility of using domestic materials in a high-speed electric generator. The features of Japanese electrical steel 20NTN1500 and domestic-made electrical steel grades 2420 and 2421 for the stator magnetic circuit are shown. The features of American steel AISI 455 and structural steel grades Steel 40, Steel 40H, Steel 45 are considered in the case of a rotor. A feature of the use of structural steels in the design of the high-speed electric generator rotor for micro-gas turbine plants is the need for precise observance of the rotor heat treatment mode after its manufacture, control of the dimensions and quality of surface treatment.
