Notes:
The next design feature I’d like to consider is rotation drive mechanism
Belt drive mechanism: The rotational driving force is transferred to the rotation section of the gantry, via a belt from a motor mounted on the fixed section.
Induction motor: A magnetic field, generated by coils in the fixed section of the gantry, induces motion in the rotation section of the gantry. A system using this type of drive mechanism is less likely to suffer from gantry vibration during high-speed rotation.
GE uses the belt drive mechanism. The other manufacturers use the induction motor.
