Renewable Energy Exam Study Guide.
Rotor - answer✔Bolted to the main shaft and consists of three blades that catch the wind and turn
Gearbox - answer✔Converts 22 rpm from the rotor to 1500 rpm needed for the generator
Generator - answer✔Makes electricity when it turns, sending the current down the tower in the cables
Yaw Motor - answer✔Turns the nacelle so the rotor faces the wind
Anemometer - answer✔Measures wind spend and sends that information to the control tower
Mechanical Brake - answer✔Makes sure the rotor will not start turning while it is being repaired or
serviced
Main Shaft - answer✔Connects the rotor to the gearbox
Yaw Bearing - answer✔Track which turns the nacelle and rotor into the wind
Radiator - answer✔Cools the water in order to cool the generator
Controller - answer✔Computer which controls the parts of the wind turbine
Wind Vane - answer✔Measure the wind direction so that the nacelle and rotor can be turned properly
Small Shaft - answer✔Connects the gearbox to the generator; turns very fast
Renewable Resource - answer✔Resource that can be replenished by a natural process in a human's
lifetime
Nonrenewable Resource - answer✔A resource that cannot be replenished at a scale comparable to its
consumption
Top of a hill - answer✔The best place to place a wind turbine
Tower - answer✔Made from tubular steel and supports the structure of the wind turbine
Nacelle - answer✔Houses all of the parts of the wind turbine and turns so that the rotor is facing the
wind.
Transformer - answer✔Takes energy from the generator and distributes it to homes, businesses, etc.
