W orld-wide references ABB has installed more than 150 MEGADRIVE-LCI units with total power of 1140 for applications power plants, the oil, gas and chemical industries, water pumping stations and test bays. Over the units supplied for driving boiler feed pumps electricity power plants and operate the high-speed range to 6000 rpm.100 % Motor frequency: Hz The maximum speed function the number poles, e.80 MW Speed control range: (0).Power and speed range Power MW Motor speed 1000 rpm The permissible relationships between power and maximum speed for MEGADRIVE-LCI..g.e... These together with approximately 360 LCI. 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. They have ratings between MW and MW. 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.. Another noteworthy project was for converter-fed high-speed synchronous motor (14 at 6,400 rpm) replace steam turbine driving a five-stage compressor ethylene production plant Italy.). Technical data Typical power range: 2. two-pole machines have maximum speed 7500 rpm. The maximum speed primarily determined by the design the motor, i.. 4 .. the physical forces which the rotor subjected.10.ST units supplied for soft start synchronous machines, make ABB leading supplier of this kind drive technology
