摘要

This article presents the results of designing a high-velocity permanent magnet turbo generator. The strength of the rotor magnet system is ensured, losses in the magnet body minimized, and magnets heated up using a sleeve (shroud) made from a special alloy. The losses in the statorcore steel and the saturation factor are minimized using the 49 KF material. The generator design includes a gasdynamic stator suspension. The generator has a two-loop cooling system that makes use of the gas turbine actuating medium (He circulating at P= 20 Bar and T= 360 K). Some of the He is delivered to the heat exchanger at P= 20 Bar and T = 650 K, where its temperature is decreased to 360 K; the gas then is delivered to the loops to cool the active parts of the generator. The temperature distribution in the active zone of the generator cooled by He is calculated.
