in parallel and can be used together or individually. This ensures
that they will run smoothly for the entire five years planned for the
mission. The key factors when selecting the drives were their low
weight, energy efficiency, and resistance to vibration.

Testing at IABG facility in forest near Munich
could potentially cause interference, such as extra currents generated by the cameras on board to take images of the Sun.

From the Sun to Mars for Maxon's
micromotors

Solar Orbiter will fly within 45 million
kilometers of the Sun bringing it closer
than Mercury, its nearest planet. At this
distance, the side of the probe facing
the Sun will be exposed to intense heat,
more than 500 degrees C. A heat shield
will protect the valuable instruments on
board the probe, the shutters provide
a view of the Sun only when measurements are being taken.

Equipped with their powerful permanent magnets in the core,
the centerpiece of the brushed DC motor is its patented ironless
rotor. This means cutting-edge technology for compact, powerful
drives with low inertia, says Maxon. Due to the low mass moment
of inertia, the motors have a very high acceleration. They can be
configured in many options.

The drives with Neodymium motorsmade by Maxon are among the components used in the X-ray
telescope. Two specially modified DC motors with diameters of
13 mm move an aluminum attenuator, which slides in front of the
telescope's 30 detectors as required. The micro drives are wired

The design is based on micromotors that will soon be headed
to Mars. Preparations are underway for the next two major Mars
projects which are scheduled to start in the summer of 2020,
NASA's Mars2020 Rover and ESA's ExoMars Rover. The aim of
both missions is to provide new information about the Red Planet
including detecting whether life has ever existed there. Mars2020
will also carry a small helicopter to deliver a proof of concept that
flights are possible on Mars despite the very thin atmosphere.
Maxon drives are used for mission-critical tasks in both projects,
including wheel drives, handling of soil samples, and steering the
Mars helicopter.

Solar Orbiter is an ESA-led mission with strong NASA participation. The prime contractor is Airbus Defence & Space in Stevenage, UK. The probe will journey for almost two years before it
can start taking measurements. The mission is scheduled to end
in 2025.
