In this paper, a performance analysis of Permanent Magnet Synchronous Machines (PMSMs) for High-Speed Flywheel Energy Storage Systems (HS-FESSs) to be employed in Electric and Hybrid Electric Vehicles is presented. It aims to identify optimal speed ranges, within which HS-FESS performances can be appropriately maximized, especially in terms of efficiency. Thus, a modeling of PMSM operating constraints (voltage saturation, current limitation, etc.) is carried out at first. This enables an appropriate analysis of PMSM performances within its operating boundaries. As a result, PMSM efficiency maps can be achieved, which allow the identification of suitable operating conditions for HS-FESS. The effectiveness of the proposed approach is proved by means of both analytical and simulation results, which regards two high-speed PMSMs operating over different torque, power and/or speed ranges.

Abstract

In this paper, a performance analysis of Permanent Magnet Synchronous Machines (PMSMs) for High-Speed Flywheel Energy Storage Systems (HS-FESSs) to be employed in Electric and Hybrid Electric Vehicles is presented. It aims to identify optimal speed ranges, within which HS-FESS performances can be appropriately maximized, especially in terms of efficiency. Thus, a modeling of PMSM operating constraints (voltage saturation, current limitation, etc.) is carried out at first. This enables an appropriate analysis of PMSM performances within its operating boundaries. As a result, PMSM efficiency maps can be achieved, which allow the identification of suitable operating conditions for HS-FESS. The effectiveness of the proposed approach is proved by means of both analytical and simulation results, which regards two high-speed PMSMs operating over different torque, power and/or speed ranges.
