Vacuum-Resistant Stepper Motor

Product Overview

The WHEATSTONE Vacuum-Resistant Stepper Motor is specifically engineered for operation in high-vacuum and ultra-high-vacuum (UHV) environments, where conventional motors would fail due to outgassing, thermal stress, or material degradation. Utilizing vacuum-compatible materials, specialized lubricants, and precision winding technology, this motor ensures stable torque, accurate positioning, and long-term reliability in demanding vacuum applications.

Key Features

• Vacuum Compatibility – Manufactured using low-outgassing materials compliant with vacuum industry standards.

• Thermal Stability – Optimized design for efficient heat dissipation and stable operation under vacuum-induced thermal stress.

• Precision Control – High step accuracy with minimal backlash for precise motion control.

• Lubrication System – Uses vacuum-rated dry film or solid lubricants to ensure long service life without contamination.

• Customizable Options – Configurable step angle, torque, and winding specifications to fit specialized equipment.

• Sealed Construction – Optional hermetic sealing to further enhance vacuum performance.
