The first, dedicated to servo drives for magnet synchronous motors, was presented by Andoni Larrañaga (engineer in the Electric Motor R&D Department) and Asier Salsamendi (Production Engineering Technician).
The aim of this conference was to apply what students have studied throughout the course of their academic careers. Among other aspects, this included the application of control loops in permanent magnet synchronous motors (position, speed and current).
The application and operation of different elements available at Fagor Automation was demonstrated, as was the functioning of different models of encoders, including their inner mechanics, signal types, precisions, the information they provide, etc.
Finally, they discussed the details of parameter settings for permanent magnet synchronous motors. On the one hand are the essential fixed parameters, and on the other, those referring to mechanics and work cycles. Students conducted practical tests with the latter parameters for real drives.
The second session, this time led by Andoni Larrañaga, dealt with vibration analysis in rotary machines.
The goal was to add to the students’ knowledge in a new subject area: vibration analysis.
First of all, basic vibrations were analyzed and once the basic notions were understood, they began to examine the foundations for comprehending a more complex vibration analysis.
The vibrations of different frequencies were analyzed that can be generated by a motor: bearings, cogging, natural frequencies of the materials themselves, etc. Finally, once the importance of the vibrations was established in machines today, the session examined the methods, elements and tools that are used to measure and analyze them.
After 5 years of conferences, there is still interest by both professors and students alike, as demonstrated by the surveys administered at the end.
“It is something that breaks away a bit from our everyday routine, and which we are very excited to do. We try to contribute our grain of salt to the training of future engineers, showing them part of the systems that Fagor Automation offers the market,” Andoni himself says.
On behalf of the Fagor Automation team, thank you very much for attending.
