Wind energy
axial alternator
Energy; Wind energy
An alternator design where a flat disc carrying magnets on the face (the Armature) rotates near a flat disc carrying coils (the Stator).
bearing
Energy; Wind energy
A device that transfers a force to structural supports. In a wind generator, bearings allow the shaft to rotate freely, and allow the machine to yaw into and out of the wind.
belt
Energy; Wind energy
A device for transferring power from a rotating shaft to a generator. Allows the use of pulleys to change the ratio of shaft speed to and from the generator.
braking system
Energy; Wind energy
A device to slow a wind turbine's shaft speed down to safe levels electrically or mechanically.
coercivity
Energy; Wind energy
The amount of power needed to magnetize or demagnetize a permanent magnet. Measured in MegaGauss Oersted (mGO)
