Am a stuent doing engineering ,i want derivation of emf equation of a alternator
I donno anything about it that's why am searching for it i need derivation for torque equation of a alternator

Power and Torque
Using the simplified generator power flow diagram it can be seen that the difference between mechanical input power and electrical ouput power is the combined rotational loss plus I2RI2R losses. If the field currend is provided by a pilot exciter and synchronous exciter, the power for the rotor I2RI2R losses is supplied from the mechanical system and may be grouped with rotational losses. Power converted, Pconv is the product of electromagnetic torque and speed Pconv=τωs Pconv=τωs and will equal the power delivered to the armature circuit. Power and torque equations for balanced synchronous generators can then be obtained from analysis of the per-phase equivalent circuit and phasor diagram. to get full about it please visit; http://people.ucalgary.ca/~aknigh/electr...orque.html |
