Rotor, stator, diode rectifier, slip rings, and bearings exposed on a Bergey XL.1 1 KW generator.

A cross-section of an extruded carbon-fiber blade shows the airfoil shape.

The stator from a 10 KW Bergey Excel showing multiple windings. A bearing in the center supports the rotor.

Slip rings and brushes, and yaw bearing assembly from an ARE wind turbine.

One feature of Southwest Windpower’s controller is to rectify the turbine’s AC output to DC for battery charging.

As the wind approaches this turbine’s rated speed for maximum power, the rotor begins to swivel out of the wind to prevent overspeed. (Before)
