waleed2010 Posted March 26, 2010 Report Share Posted March 26, 2010 Hello there,I have done some research on this topic. I know alternator got 2 main parts rotar and stator, my question is about the rotar and stator. I would like to know whether the rotating part is got the rotating magenetic field (if that is the case, is it the magnet permant magnet or its just iron core with got winding and its magnetise) and stator got windings. So is that when roataing magnetic field rotates (rotar) and induce the current in stator winding? correct me If I am wrong. Plesae educate me (I am talking about alterntors used in Disel or Gas generators).Advance Thanksmad(e)_in_electronics Quote Link to comment Share on other sites More sharing options...

indulis Posted March 30, 2010 Report Share Posted March 30, 2010 An alternator does not have any magnets in it. Google PM motors, altenators and generators (a DC motor run "backwards")... plenty of info on how they work.The field isn't really "rotating", the commutator changes the flux direction on the rotor pole windings to repel against the field windings flux.

Kevin Weddle Posted March 30, 2010 Report Share Posted March 30, 2010 Inductors produce a magnetic field, just like a magnet. I imagine magnetic based generators are still being used because of their advantages. Quote Link to comment Share on other sites More sharing options...

And after you explain that, explain to everyone what role the strength of the flux field has to do with how much power you can get out of a "genarator".
