The generated emf depends on the speed also because e=flux (no of conductors) (speed) (poles) /60a.

How it come?

Tanjeet said:   10 years ago
e = (PNZ(flux))/60A).

David said:   8 years ago
Where did the 60 A come from? Please explain it @Tanjeet.

Eg=Φ Z N P/ 60A..

Generated vg directly proportional to speed. So Eg increase N is also increase.

E= π*Z*N*P/60A.

In which way, Explain, please.
