WEG Germany GmbH has supplied a 45-tonne, 14,000kW, 10,000V high voltage slipring motor for the testing of huge radial, axial, and geared compressors at MAN Turbo AG’s Oberhausen plant. Designed and manufactured by WEG to exacting customer specifications, the ‘M’-Line slip ring motor is special due to its highly robust design, which enables it to withstand the rigours of movement around the test area, by cranes and lifting tools, and yet still provide reliable operation under severe test conditions. In addition, the motor has two conical shafts, allowing the connection of steam turbines or expanders to the second shaft end, raising its mechanical transfer rating to 20,000 KW.
