Theta Rotation Axis parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Servo Motor 4 parts 1× Brushless motor with an integrated encoder or resolver, driven in closed loop to hold commanded position, speed, or torque precisely.
2 Helical Gear Pair 1× Two meshing helical gears forming one reduction stage that steps torque up and speed down between parallel shafts with quiet, continuous tooth contact.
3 Theta Slewing Bearing 2 parts 1× Large-diameter bearing carrying the rotating knife assembly.
4 Slip Ring 1× Rotary contact passing power and signal to the continuously rotating head.
