Domestic Wind Generator
What is the most common setup for an AC electric generator? Two choices, 10 points?
I have made these two choices up myself, as I know it should be either one of these but I don’t know which one…
A. Stator windings, coils of wires as rotor. Current fed to rotor, become electromagnet and produces magnetic field, rotates (through heat, wind etc) and induces current in stator windings which AC.
B. Permanent magnets as stator, coils of wires as rotor. Rotor rotates through heat, wind etc. and has current induced in it. Does not have commutator (ie. same setup as DC electric generator but no commutator).
I am writing a report on it, and I want to do the most common one. I assume it would be the one used in power stations to ‘generate’ domestic electricity. If possible, could you please tell me what that type of AC generator is called also after choosing A or B?
Thanks in advance. 10 points for best answer promised.
Anyone? Please help?
I’m not sure if you’d understand EPK’s somewhat comprehensive response, so to give you straight answers to your clear questions:
Your version A is appropriate. It corresponds to the basic configuration of generators used in power plants. It’s called either an alternator or a synchronous generator.
For the sake of clarity note that current to the rotor winding is DC and the stator winding is 3 phase AC
