Type of option
The construction types can be both SINGLE-BEARING (STANDARD) and DOUBLE BEARING.
The double bearing is less required, more expensive and it involves the use of an additional component, the flexible coupling.
KEEP IN MIND
The alternator shaft is supported by two bearings making the machine more robust.
In the front part there is the alternator shaft that will be coupled to the engine…
There are different types of AVRs available, which can be used depending on the application.
WHAT IS AVR ?
IT IS AN ELECTRONIC DEVICE;
IT ADJUSTS THE ALTERNATOR OUTPUT VOLTAGE;
IT PARTLY PROTECTS THE ALTERNATOR;
IT STABILIZES THE OUTPUT VOLTAGE;
NORMALLY IT IS MOUNTED ON BOARD OF THE ALTERNATOR.
KEEP IN MIND
Each Alternator manufacturer has their own types of AVRs with their own technical…
The PMG (Permanent Magnet) directly powers the AVR; in this way, the load and the AVR are isolated, the AVR continues to be powered and it is less affected by the voltage fluctuations that may be present in the load. By isolating the AVR , it allows to get better load acceptances.
SOME EXAMPLES OF APPLICATIONS THAT REQUIRE PMG:
UPSs (static uninterruptible power supplies)
INVERTER and SOFT…
A protection systems capable of withstanding the harm caused by the various different types of attack encountered. In severe environmental conditions, the traditional polyester varnish applied to the windings can be subject to ageing or premature corrosion. In such cases, the machine protection should be reinforced.
Typically these are special resins that act as a physical barrier to humidity,…
On the alternators, each of the openings associated with the cooling-air path must be fitted with a screen and, on occasion, an additional louver to comply with the relevant EU Directives for ac generators (alternators); primarily to protect against the ingress of solid objects, plus the harmful ingress of liquids.
Canopy Additional protection
Special inlet AIR filters with different IP…
It is an electric resistance, inserted in the alternator structure.
It keeps the alternator heated in the period in which it is not in use.
The anti-condensation heating works when the alternator is not in service.
It is highly recommended for applications close to aggressive environments (humidity, high salinity, high thermal excursion).
Different types are available, depending on the…
APPLICATION TYPICALLY USED IN RENT SECTOR OR WHEN TESTING EQUIPMENT WITH DIFFERENT FREQUENCIES AND VOLTAGES.
If our customer requires a machine that switches from 50Hz to 60Hz, the voltage must be adjusted according to the request:
Installation of the AVR in the control panel.
Fine voltage adjustament:
By acting on the AVR
By acting through a potentiometer mounted on the genset control panel…
