Our 215-HZ, the 1kW 350 RPM Alternator has been used in small wind turbines for over 5 years. This unit can be configured for use with a turbine mounted on the body of the alternator turning at 350 RPM. Our Outrunner Alternator operates by spinning the rotor on the outside of the fixed stator, efficiently producing electrical energy making it a versatile choice for wind applications.
