CONSTRUCTION DETAILS
Housing in aluminium extruded section into which a stator pack is inserted.
Such stator pack is obtained from low loss magnetic sheet.

Front and rear shields are in die-casting aluminium alloy with ventilation opening protected by heat resistant mesh.
Rotor in magnetic sheet slotted to protect the rotor winding from overspeed .
Shaft in C40 steel, self-lubricated bearing with double seal protection (2RS).
Axial ventilation with polyamide fan - radial blades.

Accurate machining of coupling elements guarantees an easy and sure assembly.
Generators are manufactured with shapes B5 / B9 and B3/B14 with dimensions and coupling flanges as stated in the overall dimensions table.
Stator winding insulated according to F class, H class rotor impregnated with epoxy varnish.
The normal degree of protection is IP121 according to UNEL 05515-71 and IEC 34-5 international standards.
On request is possible to supply IP23.

TECHNICAL CHARACTERISTICS
The data stated in the tables are applicable to following conditions: environmental temperature not exceeding 40°C - height not exceeding 1000m a.s.l. - continuous duty.
Self-excitation is by residual magnetism, whereas self-adjustment is obtained by the compound system.
With generator running, voltage accuracy is kept within ±5%. With full load on at cosø=1 to 0.8, the voltage drop is kept within ±8%.
three-phase asynchronous motor starting: With a 20% drop at terminals the generator delivers current equal to ~ 3ln (three times the rated current).
With a symmetrical short-circuit the current remains more than 31n (three times the rated current).
With full load on the voltage returns to its rated value in about 0.1"
