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

How it come? |

e = (PNZ(flux))/60A). |

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. |
