Taguchi Method for Design and Optimization of a High-Speed Permanent Magnet Synchronous Generator Protected by Retention Sleeve

Abstract

: High-speed permanent magnet synchronous generators (HS-PMSGs) suffer from mechanical stresses due to high speeds. With the predicted mechanical stresses that may occur in the rotor of the HS-PMSGs, the design of these machines should be very accurate. So, for the HS-PMSGs, a proper electromagnetic coupled with mechanical design is a critical issue. This paper presents a novel method for the electromagnetic and mechanical design of an HS-PMSG by finding an appropriate dimension of the retention sleeve and permanent magnets (PMs) based on the well-known Taguchi optimization method. A 40-kW, 60-krpm, 2-poles and 18-slots HS-PMSG is designed at the first step
