Situation:
A global supplier of electromechanical systems and services for hydropower plants is one of the leaders in the world market for hydraulic power generation (generators). A problem has arisen in a 10MW generator. A magnetic module has broken loose, causing the generator to jam. A loss of over 100,000 euros is incurred for every day that the generator is not functioning.
Complication:
The rotor is no less than 3.1 metres in diameter with 20 poles. It contains 1600 magnets that are bonded in a specific way.
Question:
The customer asks Bakker Magnetics to build a new rotor because of its knowledge and experience in bonding magnets to rotors. This will help to avoid the kind of problems the customer is now facing.
Solution:
Bakker Magnetics develops tooling to handle these types of large rotors in the factory. Bakker Magnetics also develops tooling to be able to bond the magnets to the rotor in a safe, smart and efficient way. The customer wants a proven adhesive, suitable for this application. This is why Bakker Magnetics specifies an adhesive test that reflects the real-world conditions. This involves issues such as temperature cycles and specific adhesive thicknesses.
Result:
Bakker Magnetics has ensured, in a relatively inexpensive way, that the continuity of the hydropower plant is better safeguarded. As a result, major financial losses due to breakdowns are avoided. In addition, the solution provided by Bakker Magnetics has ensured that the business process runs considerably more safely.
