MARELLIMOTORI ALTERNATOR 1650KVA MJB 450 LA4

MARELLIMOTORI MJB 450LA4 ALTERNATOR 1650KVA THREE-PHASE

MARELLIMOTORI MJB 450LA4 is a three-phase alternator capable of delivering a power of 1650KVA 1320KW, comes complete with AVR.

The frame of the alternator designed by MarelliMotori is equipped with side ribs to increase the resistance in addition the construction is made of strong welded steel
The alternators MarelliMotori 1650KVA for continuous operation are designed to meet the vibration levels according to the standards, so they have a shielding in spheroidal cast iron or gray cast iron.

The shaft of the MJB 450LA4 is made of carbon steel and obtained by rolling. The shaft is obtained by forging from 290 mm diameter and is tested at the manufacturer in order to verify the absence of defects.

The stator/motor core of MarelliMotori is laminated and enamelled on both sides to minimize losses due to eddy currents
The rotor of MJB 450LA4 is of salient pole type, made with class H flat copper wire insulated with enamel coating.
The winding is held by high quality steel through rods.

All MarelliMotori are equipped with a large damping cage and are suitable for parallel operation with other generators, if equipped with the parallelization unit.
All MarelliMotori alternators can be designed to meet specific reactance values (x'd and x''d).

The MarelliMotori alternators are all equipped with voltage regulators. For the correct voltage supply MARELLIMOTORI MJB 450LA4 1650KVA needs an electronic control system, known as "voltage regulator" or "AVR" (acronym of Automatic Voltage Regulator). It guarantees the proper functioning of the machine and above all of the electrical network behind it.

The AVR is an electronic device that converts alternating current with frequency and voltage variable over time into direct current and thus avoids current surges.

The AVR designed by MarelliMotori is internally equipped with a radio noise filter, which allows to contain radio noise emitted by MarelliMotori generators within the limits set by the European regulations for industrial environments

Each engine has a type of connection to be connected to the alternator, so it is necessary to pay attention to this aspect; a model can also have from 15 to 20 different forms of construction!
It is always advisable to check with the help of the technical data sheets the construction form of the desired alternator.
