2.5 TECHNICAL INFORMATION
2.5.1 AC alternator
The single phase alternator is directly coupled, one
bearing, brushless, rotating field design, two poles (3000
RPM) and self regulating.
Residual magnetism causes a small voltage over the
stator windings and allows a current to flow in the
windings, which is magnified because of the feed back
effect between rotor and stator. The field windings in the
rotor are short-circuited over a diode to rectify the current.
A capacitor over an additional winding in the stator which
is at an angle with the power-winding keeps the voltage
stable within 5 % at the specified rpm and provides voltage
fall off with speed, preventing over-excitation at low engine
speeds and softening the effect of load switching to relieve
the burden on the engine.
Further technical data on the design of the alternator can
be found in drawings and diagrams in this manual.
2.5.2 Engine
The Whisper 3,5 generating set is based on the Kubota
OC60 1 cylinder diesel engine. The engine is indirectly
injected. The engine is oil cooled and the oil is cooled by a
heat exchanger and raw water. The heat exchanger and
all other parts which are in direct contact with the raw
(sea) water are made of seawater resistant material like
naval brass and gunmetal.
The engine has been specially adapted for the Mastervolt
application and is very different from the standard engine
supplied for industrial applications!
2.5.3 Digital Diesel Control system
The standard electrical engine control system is 12 Volt
negative earth, non earth return (ungrounded) is available
as optional. Check your identification data to determine
which system is applied. The system is designed
according to the "energise to run" system. The Digital
Diesel Control is a very advanced microprocessor based
full automatic system. Besides automatic start the system
offers many monitoring options. Refer to the separate
Digital Diesel Control users manual.
The microprocessor unit is located on top of the alternator.
