The thesis addresses the field of electric linear motors, with an emphasis on their
operating principles, technical design, and practical implementation in industrial
transport systems. The introductory part presents the fundamental properties of
the magnetic field and its role in generating and directing force, which is crucial for
the operation of linear drives. Phenomena such as static and dynamic magnetic
fields, longitudinal traveling magnetic fields, and the influence of ferromagnetic
materials on system performance are analyzed in greater detail.
The central part of the thesis explains the operating principles of linear asyn
chronous motors (LAM) and linear synchronous motors (LSM), with a detailed
description of the key system components, including the inverter, motion con
troller, position encoder, and relevant control algorithms, such as field-oriented
control (FOC) and direct torque control (DTC).
In the practical part of the thesis, the XTS (extended transport system) deve
loped by Beckhoff is presented in detail. XTS combines the advantages of linear
motors with advanced motion control and enables exceptional flexibility in desi
gning transport paths. The thesis describes the motor modules, movers, and guide
rails, along with their mutual interaction, which allows for contactless movement
of loads with high precision. Additional attention is given to the integration of
the system into the TwinCAT 3 software environment and the functionality of
NCT (no cable technology), which enables wireless power and data transmission
directly to individual movers, transforming them from passive transport units
into active mobile processing stations.
The results obtained from testing the XTS system on a practical model confirm that advanced linear motor solutions enable significant improvements in efficiency, precision, and flexibility in modern industrial processes. The thesis therefore connects the theoretical foundations of electromagnetism with real-world applications and provides insight into technologies that represent the future of industrial automation.
