~X-ray Exposure Device~ |
A
direct drive motor that carries
an Iron-55 sample on the armature. Instead of conventional windings a
PCB serves as both the stator and the mechanical baseplate making it
intrinsically vacuum compatible. The rotor/ source carrier needs to be
quite well balanced as the motor's torque is only about ~5N-Cm.
