PROJECT DESCRIPTION
Our work includes
research, development, design and programming of a magnetic application
demonstrators for Infineon Technologies Austria AG in cooperation with Carinthian Tech Research AG. Due to the large scope of the
project the FH - Master Student BSc Michael Huber works together with us to
realize this project for Infineon Technologies Austria AG. The benefit of this
project for the company is the capacity to be able to better illustrate the
sensor to customers in the automotive industry. The demonstrator will then be
shown at events and trade shows to interested parties to explain the operation
of this sensor.
In our case a linear
displacement measurement is carried out with a magnetic field sensor (angle and
distance sensor). With the application demonstrator you can show the use of a
magnetic angle sensor in a possible application, for example for detecting the
position of the shift lever (gear-application), or of the clutch, accelerator
or brake pedal. With this method it would be possible to save mechanical
components as well as weight in order to construct more environmentally
friendly systems.
The goal of the
project is to develop a demonstrator, which drives a linear motion of 5 cm.
This is performed by a stepping motor, which moves the magnet back and forward
to produce a changing magnetic field. The sensor, which operates with the GMR
effect, describes the variation of the magnetic field by reducing or increasing
the electrical resistance. The measured data is sent to a microcontroller to
process it further. These measurement results as well as the position of the
magnet are shown on a display. Using this touch display the operator can
control the movement of the magnet itself.
The demonstrator is
constructed as followed:
The benefit of this project
is for the research in the field of magnetic sensors as well as for the
companies involved of great importance. The usage of such a sensor could
produce more efficient and innovative systems and the parties could thus play a
pioneering role in this field of technology. It allows them to attract new
customers and increase their market area. Also the benefit to the HTL Mössingerstraße is big, because of this project further
contacts with companies such as Infineon Technologies Austria AG and CTR as well
as with educational institutions such as the FH Kärnten can be built up.
