also phrak, the lorentz force shouldn't be a problem as for half cycle its opposing force, and for the rest of half cycle its aiding force.

thanks phrak for information, actually i was looking for designing a prime mover of a generator at particular set of values. thats why i was looking at alternator drag force with load. thanks

hi phrak, thanks for the information, the factor of ~100; is it multiplication factor ? also isn't lorentz force applicable in motors only?

what parameters are needed to calculate the electromagnetic force causing slowing down of the shaft ?

thanks russ... but i am looking at only the losses and the forces that are causing the slowing down of shaft. thanks

Voltage, current, distance from the rotor and number of turns is known

thanks russ, if you could tell me how to calculate the value of the force, i'll be really grateful to you. thanks

thanks for the reply... but once again... i want to know what kind of force is causing the stall as the shaft and alternator are not physically attached... so what kind of force stalls the shaft.

see i want to know as the amperes out of alternator are increased... the shaft slows down... what force is responsible for the slowing of the shaft i'm looking for the kind of FORCE and not the relationships thanks

hi, thanks for your reply... the scene is torque is supplied by the turbine to the alternator, now please tell me how is amperage related?

hi, everyone know that when electrical load is applied to a generator, the generator slows down. Now my question is what actually slows the generator, what kind of force and how much is that force this question my sound weired to many but i need a very definite answer. thanks in advance
