/** Models an electric motor.
|
|
FGElectric models an electric motor based on the configuration file
|
|
\<power> parameter. The throttle controls motor output linearly from
|
|
zero to \<power>. This power value (converted internally to horsepower)
|
|
is then used by FGPropeller to apply torque to the propeller. At present
|
|
there is no battery model available, so this motor does not consume any
|
|
energy. There is no internal friction.
