phy SPACE
Stepper Motor Series for SPACE applications,
Standard and Customised solutions
In Focus
With 25 years of space heritage and over 300
motors in space we know how to optimise
weight, power consumption, thermal dissipation and stray magnetic flux without sacrificing precision or reliability.

phy SPACE represents a standard stepper
motor series for SPACE applications. This
series comes with features essential to usage in extreme environments. Beyond that it
is also the basis for customised projects - to
optimise motor-load coupling.

Our phy SPACE stepper motors are costefficient, clean and reliable even within
extreme environments. The phy SPACE series
is developed and built to resist vacuum, vibrations, low/high temperature and radiation
while maintaining high performance, precise
positioning, long life.

Highlights
Performance & Lifetime
phytron phy SPACE motors are based on a technology that can also be
found in the most challenging projects of our time. From a variety of satellites up to the Mars rover Curiosity: phytron motors drive applications
in distant worlds - highly accurate, reliable and durable. Driven within
their specification range, high-quality components and a proven design
make sure: These motors won’t let you down!

Cleanliness
phytron motors for use in space contain only materials that also meet the
requirements of the ECCS (European Cooperation for Space Standardisation). Thus, each material has a maximum TML (Total Mass Loss) value
of 1% and a maximum CVCM (Collected Volatile Condensable Materials)
value of 0.1 %. You will receive your space motor, double-wrapped and
vacuum-sealed.
