A WEG turnkey system including transformers, MV motors and MV frequency inverters is used to automate a crane that carries molten metal at a plant in Brazil. Usiminas, a producer of iron and steel, employs the crane, which is one of the very few in the world to be controlled by a PLC and digital frequency inverters connected over the Profibus-DP communication network.

 

According to the company’s press release, WEG’s motors are designed for use in difficult operating environments, notably offshore oil and gas installations where safety and reliability is necessary. The MV motors achieve high-voltage efficiency while minimizing components levels. They also employ high-voltage IBGT’s to reduce harmonic currents to low levels.
