Question

Please answer the following questions in detail ( two paragraph at least ):

What is the basic difference between synchronous machine and induction machine? Why induction motor is more common as compared to induction generator?

Answer 1

@What is the difference between Induction machine? sunchronais machine and 1. Induction machine works on the principle a incaple of magnetic aks on the principle of Induction synchronas machine operates on the principle of magn Locking between rotor poles and rotating magnetic field poles 2. Induction motor is single excited machine ier, pover is only supplied at stator. Whereas Synchronous motor is double excited machine, it has ac supply at started and dc is supplied to the field poles of machine (synchronous machine has stationary armature and sotating pole machine). 3. Three phase Induction motor is selt starting whereas synchronous moto is not self starting. 4. Synchronous nota can be operated for all power face Induction motor operates only an lagging power factor 5. As the name say synchronous motor will always rotate In Synchronous speed, whereas Induction motor has a concept of ship will never attain les synchronous speed CamScanner

Induction motor is not much used as generator because it requires reactive power for its operation. That is reactive power should be supplied from outside and If it rung below the synchronous speed by any means, it consumes electrical energy rather than giving it at the output. so, as far as possible, Induction generators are generally avoided. That's why Induction motor is more common as compared to Induction generator, Scanned with CamScanner
