EMZ supplied a 33 ton engine for a raw mill fan operated in a cement plant in Cyprus. Before the manufacturing started, EMZ technicians carried out the detailed technical clarification on-site. The top priority was to ensure the electrical as well as the mechanical interchangeability to the existing ABB motor in frame size 900. The winding of the speed-controlled motor had also been optimized for the operation with an ABB ACS6000 frequency converter. The commissioning, as well as the optimization of the existing oil supply system for the flushing oil lubricated plain bearings, was carried out by the EMZ service team in September 2019.
