1MW Clones for Turbine Start-Up
Reverse-Engineered Double-Shaft Motors for Power Plant Application

When reverse engineering meets high-stakes performance, Valiadis delivers. We recently completed the first of two 1MW / 2-pole electric motors, fully reverse-engineered to serve as starter motors for a power plant turbine.

The project involved:

• Recreating an old Alsthom motor

• Achieving a matching or improved torque-speed curve

• Integrating a double shaft configuration:

  • One side coupled to a pony motor

  • The other to the turbine shaft

The customer provided a damaged original motor, which we used as a reference to carefully study the stator and rotor construction. From there, we engineered an optimized solution, maintaining full dimensional compatibility while ensuring reliable and efficient turbine startup.

The first motor has already initiated turbine operation, and the second unit is en route to complete the system.

Reverse-engineered. High-performance. Mission critical.
