2.2
Coupling
The coupling (flange coupling) connects the gas spark-
ignition engine with the three-phase synchronous
alternator.
Components
The flange coupling is made from silicone rubber, is
highly elastic and can be attached axially. It allows a
connection between the gas spark-ignition engine and
the three-phase synchronous alternator that is elastic to
torsion. The disc-shaped rubber body stressed for the
torque-to-bore volume ratio dampens the torsional
oscillation which makes it possible to compensate for
defects in axial alignment.
The rubber disc elements are directly start vulcanised
onto a hub body on the inner diameter. There is cam
meshing for the coupling flange on the scope of the
element which creates a positive locking plug-and-
socket connection in operation that is almost free of
play.
2.3
The three-phase synchronous
alternator
The three-phase synchronous alternator generates
electrical power with the aid of its rotational movement.
The three-phase synchronous alternator is driven by
the gas spark-ignition engine through a coupling. It is
flanged onto the gas spark-ignition engine via an
intermediate casing.
Components
The three-phase synchronous alternator is equipped with
automatic cos-
φ
regulation for operating between
φ
=0.8
inductive –1.0, with an adjustable static unit, electronic
voltage regulation with a low speed guard and an
additional permanent magnet exciting machine.
The standard 2/3 chorded stator winding allows low-
harmonic wave network parallel operation. A damper
winding is installed for parallel operation with other
alternators. A winding temperature guard is also installed.
Special characteristics
This brushless self-exciting three-phase internal pole
synchronous alternator satisfies the requirements in
accordance with VDE 0530, DIN 6280 Part 3 and the
quality standard ISO 9002.

Basic frame
The basic frame carries the cogeneration module (the
gas spark-ignition engine, the three-phase
synchronous alternator, the exhaust gas heat transfer
unit, the lubricating oil system and the optional noise
protection elements The cogeneration switching
cabinet and ventilator group can be disassembled for
installation. Beams can be loosened in the upper zone
and on the side in the lower zone so that larger
building components with hoisting equipment or
ceiling cranes can be lifted without any obstacles in
inspection work.
Components
The basic frame consists of a hollow-profile
construction of solid normal steel that is rigid to
twisting. The hydraulic interfaces for the gas, exhaust
gas, condensate, hot water and aggregate ventilation
are brought out on what are known as the “connecting
side” ready to be connected for the extensions
provided by the customer. The other three sides are
freely accessible to operation and maintenance.
Rubber elements are mounted on the basic frame that
takes the ventilating engine/alternator unit. The basic
frame is installed on Sylomer strips on the floor
without any fixed anchoring.
