To control the magnetic field in the rotor a slip ring ... we come at last to the doubly-fed induction generator, also known as a DFIG (pronounced “dee-fig”). It gets this name because ...
Generators and alternators differ by operation and electrical output, but function via the same principle—electromagnetic induction ... coils to create the magnetic field. An automotive alternator is ...
As with all currents, the induced current creates a magnetic field around itself. Note that this magnetic field opposes the original change. For example, if a magnet is moved into a coil of wire ...
