Three-phase synchronous alternator
50 - 60 Hz
Meccalte
The generators of this series are three-phase, with brushes and they are characterised by a compound-type regulation on the 3 phases; besides a high pickup capacity (motors startup: 1 HP X KVA) they also provide good performances under a single phase connection. With the delta connection it is possible to obtain 70 % of the three phase rated load and 45 % star connection with neutral.
They are manufactured according to the standards CEI 2-3, EN 60034-1, IEC 34-1, VDE 0530, BS 4999-5000, NF C 51-111, CAN/CSA - C 22.2 N°100-95. They are available with 2 poles in the series TR1 and TR2, and by 2 or 4 poles in the series BTO3; they can operate either at 50 or 60 Hz. These series have the stator or the rotor inclined in order to improve the wave form. The 2 pole rotors have a damping cage and all the windings of the stator have a shortened pitch to reduce the harmonic content.
General characteristics
Accessories
Ecologizer ECO1
In case of power drop, the ecologizer is a device which, by controlling an actuator, operates on the engine governor reducing its speed and allowing a reduction in fuel consumption, acoustic and atmospheric pollution.
ASR
The ASR allows a fine regulation of the brush machine voltage output, and assure a prompt motor starting capability to the generator. It has got an under frequency protection that can avoid troubles to the electrical machine during start transients of the engines or during an engine fault when the generator is under load.
