The Polar Wind Generator (PWG) series is unlike conventional PMG’s or PMA’s (Permanent Magnet Alternators), which are built to produce useable power at speeds lower than 70RPM(Revolutions per Minute) and full rated power at 400 RPM, the company said.

The Polar Wind series of generators are scalable from 500W to 10kW and higher.

Using NdFeB (Neodymium Iron Boron) magnets, VAWT Systems’ PWG-1 is a 1.2kW axial flux permanent magnet generator capable of producing usable power to the electrical grid (with optional grid-tie inverter) at low RPM’s and will allow operation at wind speeds below 15mph.

PWG-1 is available in two configurations. A low voltage model, PWG-1-LV, for battery charging and a high voltage model, PWG-1-HV, for connecting directly to a grid-tied AC inverter system.

The company added that these generators are suited to Vertical Axis Wind Turbines (VAWT’s) as they operate at lower RPM’s than traditional Horizontal Axis Wind Turbines (HAWT’s) and allows HAWT’s to operate at lower wind speeds.

The PWG-1 is also well suited for other renewable rotational energy sources such as water (hydro) or wave power or people powered (bicycles and exercise equipment).
