Permanent Magnet

Our proprietary permanent magnet generator is central to the Northern Power 100’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 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 100 generator is cooled directly by the wind, with no auxiliary fans or air transfer through the generator needed.

"Northern Power's in-house design teams have created an advanced permanent magnet generator arrangement and 40% smaller full power converter topology – optimizing the two in combination yields a smaller, more reliable, and more efficient power plant."
