Optimum Electrical Machine Selection for Spacecraft Electro-Mechanical Battery

Abstract

—Electro-Mechanical Batteries have important advantages comparing chemical batteries and using them is popularized specially in Low Earth Orbit satellites recently. Different type of Permanent Magnet machines are used in these systems as Motor/Generator. Simplified parametric design method is given for synchronous permanent magnet and brushless DC in this paper and finite element based simulations are used to confirm design presses. Finally proper machine is selected based on important parameters in spacecraft.
