Component Specifications

Definition
A precision-engineered copper rotor component within medical X-ray tube anode assemblies, designed to rotate the anode target at high speeds (typically 3,000-10,000 RPM) while efficiently conducting heat away from the focal spot. This component ensures uniform thermal distribution, prevents localized overheating, and maintains imaging quality during radiographic procedures.
Working Principle
Operates through electromagnetic induction when integrated with stator windings, creating rotational torque to spin the anode target. The high thermal conductivity of copper (385 W/m·K) transfers heat from the tungsten target to cooling systems, while balanced mechanical design minimizes vibration for stable high-speed operation.
Materials
Oxygen-free high-conductivity (OFHC) copper (C10100/C10200) with 99.95%+ purity, sometimes alloyed with 0.1-0.3% silver for enhanced thermal stability. Surface may have nickel plating for oxidation resistance.
Technical Parameters
  • Diameter 40-120 mm
  • Balance Grade G2.5 per ISO 1940
  • Rotational Speed 3,000-10,000 RPM

Frequently Asked Questions

Why is copper used instead of other metals for X-ray tube rotors?

Copper offers exceptional thermal conductivity (385 W/m·K), second only to silver among practical metals, efficiently dissipating heat from the tungsten target to prevent melting and maintain imaging quality.

What maintenance does a copper rotor require?

Regular inspection for bearing wear, balance verification, and cleaning of oxidation. Replacement typically occurs every 2-5 years depending on usage intensity and operating conditions.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
