S08 ALTERNATOR
ALTERNATOR OVERVIEW
ECP Series alternators are self-regulated, 2 or 4-pole
brushless alternators.
They are equipped with a rotating inductor (1) fitted with
a damper cage and stationary armature with inclined
grooves.
The winding is short pitched so as to reduce the
harmonics.
The electromagnetic compatibility tests were carried out
in compliance with the standard specifications, with the
neutral wire connected to ground.
Testing in accordance with other specifications may be
carried out on request of the customer.
The mechanical structure, always very robust, allows
easy access to the connections and inspections of the
various components.
The case is made of steel, the shields are made of
aluminum/cast iron, the shaft is made of C45 steel with a
fan splined onto the shaft.
The protection rating is IP23 (higher protection ratings
can be achieved on request).
Insulation is of class H standard.
The impregnations are realized with polyester resin for the
rotating parts and with vacuum treatment for the parts
that have higher voltage such as for instance the stators.
Special treatments may also be carried out on request
