VSS - VSH stepper motors

VSS / VSH

Dominant: solutions that perform in extreme conditions

Phytron's VSS / VSH stepper motors are the result of more than 30 years of experience in space technology. The specially designed two phase, hybrid stepper motors can be used in vacuum environments up to 10 ^-11 hPa. They are optimal for extraordinary environments such as deep and high temperatures or extreme radiation intensity.
