Earth's iron core passing through it at the distance that's predicted will become a gigantic induction generator of huge circulating electrical currents.
An induction generator must be excited with a leading voltage.
In an induction generator, these distinctions are blurred, since the generated power is drawn from the stator, which would normally be considered the field.
Now what about that little problem I set you on magnetosphere induction generators, hey, have you solved that yet?
A fully rated converter can either be an induction generator or a permanent magnet generator.
Each 1.5-megawatt induction generator weighs 65 tons.
Already in the mid-nineties, the D4 was produced with active pitch regulation as well as a doubly fed induction generator.
Older style wind generators rotate at a constant speed, to match power line frequency, which allowed the use of less costly induction generators.
However, the most common method in large modern turbines is to instead use a doubly fed induction generator directly connected to the electricity grid.
Following that are discussions of microturbines and induction generators, as well as a special chapter dedicated to energy storage systems.
