S08 ALTERNATOR
MACHINE DESCRIPTION
The NPE series alternators are self-regulating, without
rings or brushes, with 2 and 4 poles. They have rotating
inductors with a damping cage and inclined notched
stators.
The windings have shortened pitches to reduce the
harmonic content. The alternators are built in compliance
with the EEC directives 2006/42, 2006/95, 2004/108
and their modifications, with the standards IEC 2- 3, EN
60034-1, IEC 34-1, VDE 0530, BS4999-5000.
The tests for the verification of the electromagnetic
compatibility have been carried out under the conditions
prescribed by the standards with the neutral connected to
the ground.
The mechanical structure, always very robust, allows an
easy access to the connections and allows the checks of
the other parts very easily.
The frame is made of steel, the flanges are made of
aluminum, the shaft is made of C45 steel with keyed fan.
The protection grade is IP21 (on request, it is possible to
realize a higher protection grade).
Insulation is class H, the impregnations in epoxy varnish
for the rotating parts and the parts with higher tension
such as the stators are impregnated under vacuum and
pressure.
In the field of interference suppression, the series
production complies with EN61000-6-3, EN61000-6-1.
DSR digital controller
The standard power supply is supplied with the DSR on
the 28-32-34 series.
The regulator is normally installed in the terminal box of
the alternator.
GENERAL DESCRIPTION AND OPERATING
PRINCIPLE
The drive motor is connected to the flange and the discs
(1) of the alternator.
The rotor of the alternator, driven by the drive motor,
generates electricity.
The cables for the user’s power supply are connected to
the terminal block inside the “terminal box” (2).
DSR digital controllers are equipped with an LED indicator.
In normal operation, the LED flashes with a period of 2
seconds and a duty cycle of 50% (1 second on, 1 second
off), in case of faults it flashes differently.
