Product Specifications

Technical details and manufacturing context for Drive System (Servo Motor & Gearbox)

Definition
The drive system, comprising a servo motor and gearbox, is a critical component of the Linear Accelerator (LINAC) Gantry. It enables precise rotational positioning of the gantry around the patient, ensuring accurate beam delivery in radiation therapy. The servo motor provides controlled motion, while the gearbox reduces speed and increases torque for smooth, stable operation under varying loads.
Working Principle
The servo motor receives position commands from the control system and adjusts its rotation accordingly. The gearbox mechanically reduces the motor's high-speed, low-torque output to a lower-speed, high-torque output suitable for moving the massive gantry structure. Feedback sensors monitor position and velocity, creating a closed-loop control system for high precision.
