The AC7 alternator is available either fan ventilated or totally enclosed. It is of a well proven design, giving high output at low speed, with a long life and minimum servicing.
It is suitable for shaft or belt drive up to 8000 RPM. Heavy duty roller bearings are fitted at the drive end and a large diameter sealed ball bearing at the slip ring end.
In addition to double impregnation of the windings with high temperature insulating material, all internal connections to the diode rectifier bridge and the diode heat sinks themselves, are fully protected with plastic coatings for corrosion resistance. The brushes and slip rings are also sealed.
