There are so many quantities which are responsible for the speed of motors, So let's start with few of them: We know Synchronous speed Ns =120f/P & S = (Ns-N)/Ns From where N = Ns - SNs i.e. N = Ns(1-S) & Hence Speed of rotor is N = (1-S)120f/P Where, N = speed of rotor f = frequency of supply voltage S = slip of motor & P = no. of poles on stator From this formula we can see that speed is depends upon frequency of supply voltage, slip of motor, poles on stator, etc. Other then these Speed also depends upon supply voltage & also on loads. .. .. .. While, In DC motors We know E = ZNP phi/60A Now N = 60AE/ZP phi Where N= speed & it depends upon the following quantities: A = no.of parallel ways Z = no.of conductors P = no. Of poles Phi = flux cutting the conductors etc. .. Please feel free to give suggestions if there is any error. .. Please support if you like this: SOCIAL HANDLES Website: curi...
