ABB has launched a new 4‑pole generator for turbines, claiming higher power levels mean that end users require fewer genset units.

The new 1400 frame size synchronous generator (pictured) expands ABB’s AMS platform. Covering a power range from 60 to 85 MVA at voltages from 3 to 15 kV, the new 4-pole generators enable higher unit powers and more economical genset designs, ABB says, noting that the 4-pole generators offer compact size, lower weight, better efficiency, higher inertia, shorter delivery time, lower running costs and simplified maintenance.

They are also more reliable in demanding start-stop mode as they operate below the critical vibration speed area, Switzerland-headquartered ABB adds.
