4.5 Drive types
4.5.1 Single-bearing generators (only BG 132)
Single-bearing generators are designed exclusively for direct attachment to
the drive unit. The shafts of generator and drive unit are directly connected
to each other and the bearing of the drive unit serves as a second bearing for
the generator.
The generator runs at the same speed as the drive unit. The drive unit must
be running at the correct speed to avoid operating the generator at an under
or overspeed. Under or overspeed operation can impair the function of the
generator or may even damage it.

4.5.3 Direct connection via a coupling
The shaft on the generator is joined to the drive shaft of the drive unit via
a coupling. The generator runs at the same speed as the drive unit. The drive
unit must have a suitable and constantly regulated speed in order to avoid
operating the generator at an under or overspeed. Under or overspeed
operation can impair the function of the generator or may even damage it.
4.5.4 Drive via hydraulic motor
The generator is driven by a hydraulic motor. The hydraulic motor is fed from
a hydraulic system. Do not operate the generator at an under or overspeed.
Under or overspeed operation can impair the function of the generator or
may even damage it.
