so , what should i call a constant load on alternator , when it is supplying constant current or when the power output is constant. i think it should be the power? thanks

load i have this very stupid doubt but i need to ask this. what does we actualy call load. In some texts that i have referred , the current supplied by,say, alternator is called load while in others the active power supplied by the alternator is called load. so what...

well, actually i was talking about the flux in induction motor . but the information on dc motor by you is quite helpful. actually i have been spending time reading books on ac and dc machines but its always so confusing and this forum really helps. thanks jim

okay. so the stator current increses when ever the rotor current increases on the demand of load. thanks for making it clear .

does the air gap flux in induction motor remain constant while it s speed changes depending on load? because over all flux is resultant of stator mmf which remain constant as long as voltage is not changed and the rotor mmf which depends on rotor current . now a s...

because G(s)H(s) is easily available in factor form as it is obtained by simply modelling the transfer functions of individual components and multiplying them . this helps in obtaining the poles and zeroes easily as opposed to closed loop transfer function whose roots are...

hey , i have the same problem too, i don't know how to start at this. please help. just tell how to proceed.

what happens if commutator is not placed on magnetic neutral plane?

i think so , the load which causes the armature to draw full rated current

yes, it means that there is no load attached to the motor shaft

does no load means that the armature draws no current from the supply.as current drawn by armature is dependent on load torque

hey, can someone please explain what exactly is d c motor running on no-load?
