Generators

Wound poles

From 50 to 500 rpm and from 200 kVA to 20 MVA

LOW SPEED GENERATORS, CLASSIC, DIRECT DRIVE, WOUND POLES

From a mechanical energy, the generator creates an electrical energy. The rotor is composed by a magnetic circuit which supplied a constant magnetic field. This rotor turns inside a stator consisted of 3 coils. When the fixed magnetic field passes in front of a coil, it leads currents inside this one. For every coil, this induction current creates a difference of potential, which is one of tensions delivered by the generator.

Possibility of static or brushless excitation with rotating diodes.
