Our proprietary permanent magnet generator is central to the Northern Power’s innovative drivetrain design. Permanent magnet generators offer high efficiency energy conversion, particularly at partial load, and require no separate field excitation system. Our permanent magnet generators are lighter, more efficient, and require less assembly labor than competing designs.
The Northern Power Systems’ permanent magnet generator was designed at a systems level in conjunction with our power converter to create an optimized solution tailored for high energy capture and low operating costs. The NPS generator is cooled directly by the wind, with no auxiliary fans or air transfer through the generator needed.
Direct drive gearless technology delivers real energy solutions directly to your distributed, utility, or specific application through our technologically advanced wind turbine. The gearless, direct drive train is at the heart of Northern Power’s leading edge “less is more” wind turbine design focus.
Our turbine’s generator and rotor are directly coupled and move together at the same speed. By eliminating the gearbox feature, we have simplified the drivetrain design by radically reducing the number of moving parts and wear items. This gearless design advancement creates direct benefits for our customers in the form of a higher-reliability turbine with lower operating costs.
