Doble Engineering has introduced an innovative approach to test generators, motors, exciters, isophase bus, switchgear, transformers, and power cables – Electromagnetic Interference (EMI) Diagnostics.

Gas turbine engines of tanks, which are land-based derivatives of aero-turboshaft engines, share core gas generator rotor structures but face significantly higher external impact loads due to combat ...

Wind turbines are growing bigger and bigger – the diameter of their rotor blades could soon reach 180 meters. But that creates a need for larger test rigs capable of accommodating the blades for load ...

May 6, 2002 — Retaining rings restrain coils, insulation and blocking near the end turns of a generator rotor. They must have high strength and fracture toughness to withstand the tangential and axial ...
