Reciprocating Engine Driven
(Delta) Diesel and Gas
Reciprocating Engine
Applications
This design has the stator mounted
into a base-frame with pedestal
bearings to support the rotor. These
are used in many applications from
Prime and Emergency Power to
Marine Power.
The speed range for these machines
is very wide. The number of poles
ranges from 6 to 22 in general.
More poles can be added to these
machines if required.
Output Range 2,500 to 45,000 kVA
Voltage 400 to 15,000 V
Frequency 50 Hz or 60 Hz
Cooling Air or Water-Cooled
The inside of a 14-pole Delta generator
Wind Turbine
Applications
Although these machines employ
the same insulation systems as
other generators, they tend to be
more specifically designed for the
application or project. The speed can
range from 17 to 1800 RPM depending
on the generator type required.
Permanent magnet generators with
no gearbox are slow speed (as in the
photo at bottom left.) This machine
is a 6 MW machine weighing in at
100 tonnes.
A similarly rated machine working at
1800 RPM in a doubly-fed induction
(DFIG) configuration would weigh
between 10 and 12 tonnes.
