VSS UHVC (Cryo): 19 - 125 mm Stepper Motors
UHVC (Cryo) Stepper Motors
Motors for use in vacuum should not only withstand the vacuum (no bursting of air inclusions), they must not contaminate the vacuum either. By selecting suitable materials and optimised conditioning processes phytron VSS stepper motors are ideally suited for use in a vacuum.
Through many years of experience with special materials for use in Space, we have put a focus on materials with minimal molecular outgassing and high heat resistance. This is the prerequisite for a high vacuum quality and genuine measurement results in scientific and medical applications.
For exact positioning in vacuum, stepper motors are therefore particularly suitable because they can precisely position even without sensitive feedback providers. Therefore phytron VSS stepper motors can be used in particularly challenging environmental conditions (radiation, cryo temperatures and in a modified design even in Space).
Since stepper motors do not generate jitter effects while holding a position, this technology is ideal for precisely aligning optical instruments, mirrors, antennas or samples e.g. in high-resolution microscopes, particle accelerators or molecular analysis devices. As a medium-sized company, we manufacture the VSS series in Germany and modify the standard motor to perfectly fit to your application.
