a report by
Mav i l o r Mo to r s , S . A .
If there is a sector in which stringent professional
standards, perfection in execution, risk-minimisation
and hygiene dominate, it is in the medical sector.
The medical sector depends on the skill and
knowledge of excellent medical professionals, and
those professionals depend on the quality of their equipment. In the last few years, the evolution of this
equipment has been extraordinary and the
incorporation of new technologies has produced levels
of precision difficult to imagine even 10 years ago.
In order to provide these new medical tools, engineers
and other professional technicians are working within
their companies to bring their initiative, skills and
ingenuity to the creation of products to meet the
constantly evolving needs of the medical sector. These
products must be designed specifically to meet the
particular needs of this sector, which include stricthygiene standards, high speed, precision and reliability.

One of the essential components of medical
technology is the electric servomotor. Motion
control is the driving force behind many medical
applications, including centrifuges, magnetic
resonance imaging (MRI), dialysis machines,
scanners, exploratory devices and all types of robots.
Motion control technology delivers the high-
precision and high-speed movement and positioncontrol required by these medical applications.

Mavilor Motors, S.A., an Infranor Inter AG Swiss
Group company, has been operating in the
automation technology field since 1973. Infranor
corporate headquarters are located in Zurich and
the group comprises 20 companies, some involved
in application and sales and others in the
manufacture of components for automation.
Mavilor forms the branch specialising in themanufacture and sale of servomotors.
At the core of the company objectives is a
commitment to creating positive partnerships with
their clients. Their 30 years of accumulated experience
– incorporating all stages of design, production and
implantation – make them much more than just
excellent motor manufacturers, allowing them to act
as technological partners with the capacity to provide
the optimum solution for any automation need. Their
highly specialised and competent team is ready torespond to the constant innovation challenges and
changing needs that characterise the medical sector.
Throughout their history, Mavilor Motors has
introduced innovative products to the motion
control industry. Their investment in research and
development (R&D) and technical experience allow
them to lead the market in offering new state-of-the-
art products every year. Modern and seamlessly
integrated production systems allow Mavilor to offer
extremely short lead times. The expert engineering
team and quality team work together to constantlyimprove both the product and the production system
in order to offer a competitively priced, innovative
and durable product to the medical industry.
Mavilor products include a wide range of direct
current (DC) continuous current and alternating
current (AC) and DC alternate current electric
servomotors. These products are unique in their
adaptability, offering both flat and elongated
geometry for the maximum flexibility to meet the
diverse needs of the market.
These electric servomotors are characterised by an
excellent capacity for acceleration, due to a design
that permits high torque with low inertia. In
addition, these servomotors offer highly desirable
weight and volume ratios – with low weight and
compact size they are capable of delivering high
torque and reaching high speeds.
Mavilor sells its products around the world through
a series of professional distributors who attend to the
needs of their clients. In this way Mavilor and its
distributors have maintained a worldwide clientele,offering technical support and post-sales service
when necessary for the applications and equipment
that incorporate Mavilor servomotors in each
market. Currently, Mavilor Motors operates

Mav i l o r Wa shdown S e r i e s f o r t h e
Med i c a l S e c to r
The Washdown series has been developed to meet
the exacting needs of the medical sector outlined by
the following elements.
H i g h S p e e d a n d P r e c i s i o n
Powerful acceleration and high speed are achieved
using Mavilor-patented technology, a slotless design
that eliminates induced currents and the magnet
temperature elevation that results. This unique non-
cogging motor has been developed to deliver sensitive
and precise position control without vibrations or
modulations, due to its singular magnet distribution.
The need for precise speed control and sensitive
positioning control in medical sector applications is
paramount. These applications demand perfection inpositioning and an absolute control of speed,
combined with extreme reliability, since any error
could result in serious consequences. That is why
instruments such as scanners, centrifuges and other
radiological and surgical equipment find their ideal
partner in Mavilor motion control systems.
High speed is necessary in many hospital applications,
for example centrifuges that require high speeds of
between 20,000 and 30,000rpm without vibrations,
with the added demand of sudden and complete
stops. High speed is also a crucial element inodontology equipment and many other hospital
instrument applications.
R e l i a b i l i t y
Each Mavilor product is the result of an all-
encompassing quality control system: Mavilor Total
Quality. This meticulous quality control produces
extremely reliable motors capable of delivering the
consistent and unfailing performance that is necessary
in a busy medical care application.

These motors were developed to withstand the
rigorous cleaning necessary for sterilisation. In
