Maxon
Ironless Armature
A
Swiss company based in Sachseln near Lucerne, making high-precision drive
systems. These
motors can be used for a wide range of applications from high-tech
medicine to robotics. Maxon is now launching EC-max motors, a modular
program of up to 120 Watt power, to offer its customers even more
benefits for their projects.
Maxon EC-max motors are electronically commutated DC motors. Designed as
internal motors, their shafts turn with no detent thanks to an ironless
winding. The worldwide patented winding, System maxon, offers even more
benefits, such as high dynamism, low inductance, high efficiency and
extreme reliability.
This robust product family features five motor sizes with diameters of
16, 22, 30, 35 and 40 mm. Each motor type is available in two lengths,
a short or a long one which is almost twice as powerful. The motor can
be combined with a gearhead, encoder and/or brakes depending on the
application. Given that motors have several types of winding,
gearheads have several reduction ratios and encoders have a wide range
of pulses, the variety of combinations is an astonishing 10,000 or
more.
Maxon
Motor AG specializes in the development, manufacturing and sales of high
quality drive components and systems under the trade mark maxon motor.
The company's newly established manufacturing facility in the heart of
Switzerland features the most modern equipment. All key components are
manufactured in-house with custom design machinery. Their key technologies are three winding processes, motor
manufacture and gearhead production as well as the application of
high-tech ceramics and magnetic encoder components.

UNITED
KINGDOM
It is a measure of Maxon Motor UK's success that much larger premises
have become necessary within just three years of being established as
UK subsidiary of the Swiss-based company. This is well ahead of the anticipated growth schedule.
The new address, Maxon House, is still on Hogwood Lane in
Finchampstead, Berkshire, but has 1137m2 of workspace - almost three
times the size of the original premises.
Acknowledged as a leading manufacturer of precision electric
motors and drives, Maxon Motor products are to be found in just about
every application imaginable. From the new premises Maxon Motor UK will be better placed to deliver
the expanding and seemingly endless range for which the company enjoys
an unrivalled reputation. Keith Ellenden, CEO of Maxon Motor UK, says: "This success is
especially satisfying because it has been achieved in a tough economic
climate.
Key factors have been the depth of range that offers a good choice for
each application, reliability. Maxon's engineers are
recognised as some of the most knowledgeable in the industry.
Working closely with customers' design teams, they ensure the optimum
solution to any problem whether by pinpointing the perfect
'off-the-shelf' motor or by designing a tailor-made product exclusive
to the application.
NASA
MARS ROVER MOTORS
Maxon
motor provided 39 miniature
motors for two new Mars rovers, sent to the Red planet
in 2003. The motors, which are just 20 millimetres in
diameter, have a long life expectancy and are designed to withstand
the extreme temperatures they will encounter on Mars.
“We build motors which are very light, can withstand extremes and
are very efficient,” Chief Executive Jürgen Meyer told swissinfo.
“They are twice as efficient as a normal motor. They will be able
to cope with the temperatures which can be as low as minus 100
degrees Celsius.” Maxon has been collaborating with the Mars
missions since 1992 when Nasa asked the company to supply motors for
the Sojourner mission. Eleven Maxon motors were used in the 1997
Sojourner rover. The new rovers are larger and will have 39 motors,
each costing about SFr200 ($118).
NASA Mars Rover
The
new rovers will have far greater mobility than their 1997
predecessor and will be able to travel about 100 metres each Martian
day (which is 41 minutes longer than an Earth day). Each robot
will carry a sophisticated set of instruments, which will analyse
rocks and soil to explore Mars’ climate history and search for
signs of water and life. Surface operations will continue for at
least 90 Martian days.
The machines will be identical to each other but will land on
different regions of Mars. To make a safe landing, a supersonic
parachute will slow their descent. Then airbags will inflate around
the craft at about 300 metres above the Martian surface. The
first Mars Exploration Rover spacecraft was scheduled to be launched
from Cape Canaveral, Florida in June 2003. It will enter the Martian
atmosphere in January 2004. The second craft will soon follow.
Over the years, Maxon has supplied about 3,000 motors for a variety
of Nasa projects. Maxon builds micro-motors between six and 90
millimetres in diameter for a wide range of high tech and high
precision products. The company, founded in 1961, has 1,200
employees in Switzerland and abroad.
