Technical Definition
Geared vacuum rated motors are vacuum-compatible servo/stepper motors integrated with gear reduction mechanisms, developed based on vacuum-specific materials and lubrication technologies. They enable precise position and torque control in extreme vacuum environments, serving as core components for high-tech manufacturing, aerospace, and scientific research applications.
Main Categories
1. High-Precision Standard Series: Designed for semiconductor wafer processing, featuring low particle emission (<1×105 particles/m², particle size >0.1μm) and high torque density.
2. Wide-Temperature Radiation-Resistant Series: Optimized for aerospace exploration, operating in temperatures ranging from -196°C to 200°C and withstanding total ionizing radiation over 100 krad.
Design Philosophy
Our products are designed with core principles of high reliability, low contamination, and maintenance-free operation. We fully consider harsh industrial conditions and strictly follow full-life-cycle reliability design standards to provide stable, cost-effective technical solutions for clients.
Technical Principles
The core working principle of geared vacuum rated motors is based on vacuum-specific lubrication and hermetic sealing technologies. The complete implementation logic is as follows:
1. Low-outgassing lubricants and metal sealing structures are adopted to prevent vacuum outgassing, meeting the standard of outgassing rate <1.3×10−5 Pa⋅m3/s.
2. Efficient heat dissipation designs are integrated to solve heat dissipation challenges in vacuum environments.
3. Gear reduction mechanisms are optimized to enhance torque output while minimizing vibration (vibration amplitude <0.01 g).
Core Architecture and Innovative Design
- Vacuum Sealing Module: Uses metal hermetic structures to ensure ultra-low outgassing, avoiding cavity contamination.
- Gear Reduction Module: Adopts precision-ground gears to reduce vibration and improve torque transmission efficiency.
Comparison with Traditional Solutions
- Traditional motors cause cavity contamination due to outgassing; our products meet NASA vacuum standards, eliminating this issue.
- Traditional motors have short MTBF (around 5,000 hours); our motors achieve MTBF of 15,000-30,000 hours, reducing maintenance costs by 40%-60%.
