The reaction sphere is a magnetic bearing electromagnetic spherical actuator for satellite attitude control. The reaction sphere consists in a 3D motor composed of a 20-coil stator and an 8-pole permanent magnet rotor. The rotor is synthesized wit a mosaic of 728 cylindrical magnets glued on the rotor back-iron so as to approximate the selected magnetization pattern. These cylindrical magnets ...
