Generating electricity by moving a permanent magnet past a coil of wire is both the oldest power generation technology and today's best hope for improved efficiency in converting fossil and renewable fuels to electricity. This dichotomy is based in the simultaneous simplicity and complexity of the physics involved. New magnetic materials have greater power and heat resistance than previously thought possible. Improved computer modeling (FEA) has given a better understanding of how to optimize electrical output while the superior performance of new power electronics makes it easier than ever to put that energy to work efficiently.

Why permanent magnet generators? Because conventional induction and brush technology can't come close in terms of size, weight and efficiency. In the endless hunt for better efficiency and higher power density, permanent magnet generators are king with 50% lower losses and 2x greater output for a given weight and volume.

However, as all the continuing research indicates, capturing that potential isn't as easy as it first appears. Glacier Bay is one of very few companies with complete in-house design and manufacturing capability for the mechanical generator as well as the power electronics hardware and software. Our experience ensures that our permanent magnet generators give the same outstanding performance in the field as they do in the lab.

Glacier Bay permanent magnet generators are suitable for use with internal combustion engines, wind turbines, wave-power generation, hydro-electric installations and geothermal/steam turbines and available in:
