Cooling System
Enclosure and
Ventilation
The generator is designed for open
enclosure (WPI, IP23/24) or totally
enclosed air-to-water (TEWAC/CACW)
cooling system (top or bottom cooling).
Air is circulated inside the machine
by two internal fans and the rotor.
The radial ducts in the stator core,
the design of the end windings and a
careful review of the air path, ensure
temperature uniformity in all parts of
the machine.
