1. GENERAL INFORMATIONS

GH 225-630 type machines are designed to meet and exceed the rigorous performance requirements of industrial applications.
Their exemplary electrical and mechanical designs ensure flawless operation in the most severe, heavy duty service.
All stator cores contain high performance electrical steel laminations, with compensating windings provided in the main poles.
The standard winding insulation system employs Class H materials, but standard performance is limited to Class F temperatures to extend machine life. Where required, size GH 225 can be supplied without compensation.

SYNCHRONOUS MOTORS

As a standard, ANSALDO synchronous machines are built with either salient pole or cylindrical rotors, depending on the speed and size of the machine.

Designed to meet specific application needs on a job-by-job basis, our synchronous motors provide outstanding performance and reliability.

ANSALDO also has consolidated experience in generators coupled to diesel engines and turbines of all types.

GENERALITY

Designed to meet the most demanding requirements, the ANSALDO range of electric motors is made with structural steel frames, to offer greater strength and resistance.

The induction machines are built with an aluminium squirrel cage rotor.

The rotor pack consists of a single sheet up to size 1000, the stator is constructed as a separate unit mounted on the frame after the coils have been inserted and the whole has been subjected to the MICASYSTEM ® VPI process.

MICASYSTEM ® VPI
The Micasystem® VPI insulation system is one of the best on the market as it offers a high degree of reliability. This system is composed of a special mica tape and a mixture of solvent-free resins. Thanks to its exceptional dielectric and mechanical properties, this class F insulation system is particularly suitable for use in nuclear power plants and in highly aggressive environments.
