ATO-28 alternators are brushed, self regulating and incorporate a rotating inductor with damper cage and a fixed stator with skewed slots. The stator windings have a shortened pitch to reduce the harmonic content of the output waveform. The alternators are made in compliance with the 2006/42, 2006/95, 2004/108 directives and their amendments, and the EN ISO 12100-1, 60204-1, EN 61000-6-2, EN 61000-6-3, EN 60034-1 regulations.

Tests to verify the electromagnetic compability have been carried out in the foreseen conditions by the standards with the neutral connected to the earth.

The robust mechanical construction gives good access to the generator output connections, and allows the user to inspect the various components with ease. The casing is made of steel, the shields of cast iron, and the shaft of C45 steel and it has a keyed fan.

The mechanical protection level meets standard IP23 (upon request higher levels of protection can be supplied).

Insulation materials meet class H requirements, and all rotating components are epossy resins impregnated, higher voltage parts, such as the stators, are vacuum-treated (special treatments are available on request). Radio interference suppression meets the requirements of EN61000-6-3, EN61000-6-1 regulations.

The ATO-28 alternators comply with the EEC directives 2006/42, 2009/95, 2004/108 and their amendments; therefore they pose no danger to the operator if they are installed, used and maintained according to the instructions given by Zanardi alternatori and provided the safety devices are kept in perfect working conditions.
