Radiation Hardened Servo Motors with Wire Cover are, simply put, “special forces” capable of operating reliably in environments with high levels of nuclear radiation. Their core applications are concentrated in the following cutting-edge and highly challenging fields:

1.The Nuclear Industry: The Most Critical Area of Application

Nuclear Power Plant Operations and Maintenance: Powering key equipment such as control rods, cooling pumps, and valves to perform precise movements, ensuring the safe operation of the reactor.

Spent Fuel Reprocessing: In highly radioactive hot cells, providing power to robotic arms, cranes, and other machinery responsible for handling the fuel, enabling them to perform hazardous operations such as cutting and dissolving the fuel.

Nuclear Facility Decommissioning and Waste Management: These systems power remotely operated robots used to cut and recover highly radioactive components, maximizing operator safety. For example, the robotic arms in the hot cells at China’s Spallation Neutron Source and nuclear fuel reprocessing plants are typical applications.

Special Platform Applications: They are also used in equipment such as accident residual heat removal pumps on offshore nuclear-powered platforms, where reliable operation is required even under accident conditions.

2.Aerospace: Conquering Extreme Space Environments

In space exploration, motors must remain reliable even in the face of cosmic rays and the vacuum of space.

Spacecraft and Satellites: Used for adjusting satellite attitude, controlling antenna pointing, and deploying solar panels, these motors must withstand the effects of high-energy particles and cosmic rays.

Space Observation Equipment: These motors provide high-precision, highly reliable actuation for adjusting the optical systems of space telescopes, switching filters, and other functions.

3.Nuclear Medicine and Research: Balancing Precision and Safety

This field places extremely high demands on equipment precision and stability in radiation environments.

Cutting-Edge Cancer Treatment: In neutron-targeted therapy (NCT) equipment, frameless motors are commonly used in conjunction with radiation-shielded enclosures to precisely position patients and adjust the beam, ensuring treatment accuracy. Redundant systems are also employed to guarantee safety.

Medical Imaging and Radiology Equipment: Used in X-ray machines, CT scanners, linear accelerators, and other devices to drive the rotation of scanning gantries and the movement of collimators, ensuring the safety of patients and operators.

High-Energy Physics Research: In large-scale scientific facilities such as particle accelerators (e.g., spallation neutron sources), these systems are used to control equipment such as target station shielding and detectors, enabling them to operate stably in intense mixed radiation fields to acquire experimental data.
