Trust, resilience, and reliability
“At trade shows, online, or in conversations with our clients—ENRX was the name that kept coming up”, shared representatives for WEG in Portugal. As they were looking for solutions for induction brazing of short-circuit rings used in large electric motors, ENRX's reputation for excellence consistently stood out.
As WEG, a global leader in electric motor manufacturing, began their search for a reliable supplier, it quickly became clear that ENRX could meet their high standards.
“I’m very glad to hear they are happy with us”, smiles Gunnar Kiste, the application specialist at ENRX Norway who supported the design process. “I also have to say that from start to finish the collaboration between us and WEG has been outstanding. These people are really good at communicating exactly what we needed to know to be able to deliver a final product that works optimally for their purpose.”
When WEG first reached out to ENRX regarding this project, it was Adrian Assie at ENRX Spain who initiated contact. Recognizing the importance of a face-to-face meeting, he brought Gunnar Kiste to WEG’s new production facility in Portugal to thoroughly discuss their needs.
“We have been involved right from the design of their parts and have been able to provide advice and guidance along the way”, Gunnar says. “I believe it was a huge advantage that we have people who speak the language. Our ability to communicate in Portuguese has contributed in no small way to our seamless collaboration.”
Another key factor in WEG’s decision was the confidence that came from their parent company in Brazil, which had already used similar ENRX equipment with great success. This experience further reinforced their trust in ENRX's capabilities.
This particular equipment provided by ENRX is specifically designed for brazing copper short-circuit rings used in large electric motors, which power everything from industrial compressors, fans to pumps. WEG’s needs changed as they moved into larger facilities, which meant they needed equipment capable of handling bigger and more complex motors.
“While we could have delivered a solution for segment brazing of larger rings, that would have required a more complex and costly setup,” Gunnar noted. “WEG wisely decided to scale down to a one-shot brazing system”
While the converter that provides the heat is standard ENRX equipment, both the table and the coils are custom-designed. And the number of engineering hours invested in creating this bespoke solution were significant, according to Gunnar Kiste.
“This state-of-the-art equipment includes complete temperature regulation, allowing for precise control of the brazing process using either pyrometers or thermocouples” he says. “This is one of the many advantages induction brazing offers over traditional welding processes. Because the temperature required is lower and only melts the filler material rather than the base metals, the process is cleaner and faster, resulting in a more consistent and homogenous product. Plus, it’s faster and more environmentally friendly.”
