Abstract
An engine driven generator set includes a vertical shaft engine which rotates a generator rotor and a centrifugal fan mounted above the engine. A plenum collects cooling air blown over generator stator windings by the fan and directs the cooling air through an air duct over the engine cylinder head. Electronic circuitry is cooled by this same cooling air.
Claims8
An engine driven generator set which comprises:
- an air-cooled engine which rotates a vertically disposed shaft that extends upward from the engine and which has a cylinder head that extends laterally outward to one side of the engine;
- a generator mounted above the engine and having a rotor coupled for rotation by the shaft and a stator disposed around the rotor and supporting stator windings;
- a fan mounted above the generator and coupled for rotation by the shaft to blow cooling air over the stator windings;
- a plenum formed around the fan to confine the air blown over the stator windings;
- and
- an air duct coupled to the plenum to direct cooling air from the plenum to cool the engine cylinder head;
- wherein the fan is a centrifugal fan which draws cooling air in from above and blows it radially outward over the stator winding and into the surrounding plenum.
