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.
