Our 255-AZZ, the 2kW 300 RPM Wind Turbine Alternator has been used in small wind turbines for over 5 years. This unit can be configured for use with a vertical or horizontal axis wind turbine turning at 300 RPM. The most popular configuration on our low RPM Permanent Magnet Alternator is an aluminium body with flange mounting on either the front or the back end covers which makes it a versatile choice for wind applications.
