Rotating field
Hi Ufo,
In most text books and courses on the subject of AC dynamos develop and teach the concept of the rotating magnetic field developed from polyphase excitation of the stator. Without the rotor motion (stalled), this is traveling magnetic field around the air gap thru the machine's steel structure.
Note that the rotor can be removed and replaced with a metal egg. Likely what Tesla did. I believe Tesla is credited with discovery of this rotating field.
But yes, the moving field in this case does swing +/-. Each half cycle is unidirectional. Does' t that count?
Could you not just bias the AC applied with a DC level sufficient to keep the magnetic field from changing direction? I was about to suggest this to you on the other thread where you were using a stator before getting engrossed with Figuera.
Oh well. Carry on.
Regards,
bi
