<p>A rotor is disclosed for a galvanometer system. A rotor includes a permanent magnet core (20a), a sleeve (22a) and at least one shaft unit (28a). The sleeve encloses and attaches to at least a portion of the permanent magnet core. The sleeve is formed of a material having a density of less than about 0.2831b/in<3>. The shaft unit is attached to both the permanent magnet core and to the sleeve. An output device may be coupled to the shaft unit, and the shaft unit is formed of a material having a dynamic stiffness of at least about 1.00 x 10<9> Ib in<7>/slug.</p> |
