| Blades | Wind blowing over these causing them to lift and rotate. |
| Brake | Stops the rotor in case of emergency |
| Controller | Starts up or shuts down the machine depending upon wind speed. |
| 65 mph | Maximum operating speed |
| 8-16 mph | Start up wind speed. |
| Gear box | Connects low speed shaft to the high speed shaft. |
| Generator | Uses mechanical energy to produce 60 cycle AC electricity |
| High-speed shaft | Drives the generator |
| Low-speed shaft | Turned by the rotor between 30 and 60 rotations per minute |
| Nacelle | Connects to the rotor and contains all the internal parts of the turbine |
| Pitch | The angle the blades are tilted at to produce desired wind effects |
| Rotor | Blades and hub together. |
| Tower | Supports the nacelle and rotor; made of tubular steel. |
| Wind vane | Measures wind direction and sends data to controller. |
| Yaw drive | Used to keep the rotor facing in the proper wind direction. |
| Yaw moter | Powers the yaw drive to turn the nacelle. |
| Foundation | Anchors the windmill to the ground. |
