Simplified design of slotless halbach machine for micro-satellite Electro-Mechanical Batteries

Electro-Mechanical Batteries have important advantages compared with chemical batteries, especially in Low Earth Orbit satellites applications. High speed, slotless, external rotor, halbach array permanent magnet machines are used in these systems as Motor/Generator. In this paper proper material and structure for space applications are introduced and a simplified analytic design method is given for this type of machines. The finite element-based simulations are used to confirm the design process and show less than 4.3% error in parametric design.
