units supplied for soft start synchronous
machines, make ABB leading supplier of
this kind drive technology. the physical
forces which the rotor subjected.
The maximum speed primarily determined
by the design the motor, i. They have ratings between MW
and MW.
These together with approximately 360 LCI.. The
largest drives supplied the present
were for hydroelectric power plant the
PR China (pump rated MW) and for
the Troll project Norway, where five com
pressor drives each with rating MW
and maximum speed 3750 rpm are
installed transport natural gas.80 MW
Speed control range: (0)..e.. For the
most part, they are driving compressors,
blowers, pumps and extruders efficiently and
reliably under extremely adverse ambient
conditions (corrosive atmospheres) in
hazardous areas (oil platforms etc.).Power and speed range

The permissible relationships between power

have maximum speed 7500 rpm.10.
Over the units supplied for driving
boiler feed pumps electricity power plants
