Electrical Engineering Internship: Preventive maintenance with frequency converter data

Introduction

Are you a Bachelor or Master student in Electrical Engineering? Do you have an interest in frequency converters for power applications and do you like data analysis? Would you like to improve diagnostics and even predict upcoming failures? Then this internship might be interesting for you.

Background Information

You will be working in D&E sector within the department of EL DUV Electronics Development (EDEV) in the group Imaging & Machine Conditioning. Our team of EDEV Machine Conditioning provides electronic solutions together with the development groups from the Machine Conditioning (MC) DUV scanner department. Machine Conditioning is responsible for thermal and fluid machine conditioning solutions. It enables thermal stability in critical modules of our scanner to secure nanometer accuracy and performance.

Your assignment

Conditioning solutions often involve the use of motorized fan connected to a frequency converter (FC) for speed control. Such a design needs to be reliable, as recovery from thermal drift can take long. If the design does happen to fail, we need proper diagnostics that exactly pinpoints the failing part, such it can be swapped and recovery starts quickly. But what if we could predict failure upfront? Then our customer can avoid unscheduled downs, plan ahead for maintenance and combine it with other periodic maintenance.

As an intern your assignment will be:

• An investigation on possibilities to use frequency converter signals to predict upcoming  fan failure

For this assignment you will:

• Investigate the problem statement and context and define its scope
• Make an inventory of diagnostic possibilities with frequency converters as to distinct different internal or external failures
• Create a comparison overview of existing preventive maintenance methods
• Measure and/or analyze frequency converter power signals in search for detection and prediction of failures, and if possible create proof of concept setup
• Write a report with the results found, conclusions and proposed way forward.

Your profile

To be the perfect match for this internship, you:

• Are a bachelor or master student in Electrical Engineering, Mechatronics or similar fields
• Are bachelor or master student looking for a graduation project
• Have knowledge about electrical measurements and data processing
• Are motivated and eager to learn and look for ways to obtain information and data to perform the analysis: reach out to experts, read specifications, analyze datasheets, etc.
• Are proactive and a team-player
• Have good communication skills in English, both written and spoken

Other requirements you need to meet:

• You are available for 4-5days/week for a duration of 6-9 months
• You need to be located in the Netherlands to perform your internship. If you are currently living/studying outside the Netherlands, please express in your CV/motivation letter your willingness to relocate.
