Somtimes, I feel at night that my cyling fan is running faster (little bu noticable) than what i set it. When asked, sombody told me that it is related with this article subject.

I think that the problem is not so much the instantaneous frequency, which will be 60hz +/- a very small error, but the average frequency which must be 60hz exactly (in the USA) over a long period.
What is the constructional difference between the same two electrical equipment, one with 50 Hz and the other is 60 Hz.
Yes, but be aware of a few traps, a 60 hz transformer running on 50hz will run a bit hotter due to the higher magnetising current in the windings (less iron, lower inductance).and can I use the 50Hz device on a 60Hz mains and vice versa ?
Sorry Reloadron if I diverted your thread, but I think here is the place for a question that I've long time in my mined, since your thread directed the attention of most ETO experts.

The speed of the AC motor is determined primarily by the frequency of the AC supply and the number of poles in the stator winding, according to the relation: RPM = 2 * F * 60/p where RPM = (Synchronous) Revolutions per minute F = AC power frequency p = Number of poles, usually an even number but always a multiple of the number of phases.
