- High efficiency and reduced downtime
- Enables system decarbonization
- Requires less maintenance than a gas-turbine-driven compressor, saving 5–8 days per year for a typical 7 MTPA LNG liquefaction facility
- Customizable to best meet the specific requirements of the process technology, site topography and operating environment
- Can be configured with a variety of variable-speed drive options
- LNG liquefaction, pipelines
- Desalination, water irrigation
- Heavy industry and steel mills
Based on our extremely reliable Brush Power Generation DAX generators, our MAX synchronous motors can be fully customized to meet all customer specifications—while reducing costs and maintenance requirements, ensuring high reliability, and over 30 years’ design life.
Our typical synchronous motor system includes:
- Two-pole synchronous motor
- Variable-frequency drive
- Centrifugal compressor
- Condition monitoring
Our synchronous motors support climate change targets by enabling higher efficiency and zero emissions. They offer significant total operating cost savings by reducing the need for regular maintenance interventions, and avoiding excessive process downtime. With a global installed base of over 6,000 synchronous machines, and proven reliability in large-scale projects, they are essential tools for the decarbonization of industrial processes requiring the movement of large volumes of gases and liquids.
A synchronous 2-pole motor is one of the most efficient means of converting electrical energy into mechanical energy. A dedicated input transformer is used to adapt the network supply voltage to the adjustable speed drive input voltage. Either voltage source inverters (VSI) or load-commutated inverters (LCI) are used to drive the motors. The drives rectify the grid supply into DC and then, using thyristor-based invertors, electronically switch the DC current to produce a three-phase AC system of variable frequency and voltage for supplying the motor and controlling the speed. The drive smoothly accelerates the motor and the load from zero to nominal speed, after which the motor is automatically synchronized to the power system.
