Design of 150-kVA 24,000-rpm High-Speed Permanent-Magnet Generator for More Electric Aircrafts
Abstract
This paper presents the design of a 150-kVA 24,000-rpm high-speed permanent-magnet generator for more electric aircrafts. The additional winding is introduced to operate the machine without high-performance inverters and is here demonstrated as an effective solution to increase the capabilities of the machine under fault and overload condition. Based on the calculations, a full-size experimental SG prototype with an additional winding located on the stator back was manufactured and tested. The experimental results are in good agreement with the computer simulation data, demonstrating the proposed technology and the additional functionalities within a power-to-mass ratio of 4 kW/kg.
