Answer / masoom raza

synchronous motor and generator are same i.e
constant speed type machine but only difference
is that motor consume power and generator produce
power .it is doubly excited.
where induction motor is asynchronous machine.
its singly excited.

Answer / hussain

synchronous motor and generaor are constant sped machines
where as induction motor is variable speed machine.

Answer / lakshmiprasad

synchronous motor and generaor are constant sped machines
where as induction motor is variable speed machine.

Answer / pradyumna chandra panda

Induction motor is easily self started and it's speed is variable which is less than synchronous speed and motor leg the current behind the voltage ie poor power factor. In simple Synchronous motors are not self started (they are self started by Drive) it's speed is equal to synchronous speed and the motor maintain approximately unity power factor ie not legging.

Answer / chaitanya

induction motor is generally treated as rotating transformer becoz its working principle is same as transformer(mutual induction) and the I.M is of rotating...where as in synchronous machines the magnetic field is rotating and the speed will be constant which is not constant in the case of induction motor!!

Answer / b.arun prashanth

A synchronous motor and generator are constant speed machines and they are doubly excited machines where dc supply has to be given to the rotor ! and an induction motor always runs in a speed less than the synchronous speed ! if it reaches the synchronous speed torque = 0 hence current = 0 and the motor wont run !

Sir,In our company there are 3 caterpillar make(capacity:(1) 3.3KV,2.5MW(2)3.3KV,2.5MW & (3)3.3KV,1.9MW) & 1 deutz make (capacity:11KV,3.8MW)gas engines utilised,all are running in paralell. There are three transformer utilised,(1) 6.25MVA,3.3KV/22KV,Impedence voltage:6.7% used for two generator,both are 2.5MW(2)5.5MVA,3.3KV/22KV,Impedence voltage:7.2% used for one generator of 2.5MW & (3) 5.5MVA,11KV/22KV,Impedence voltage:7.8% used for one generator of 2.5MW.all generator breakers capacity of 1250Amps. Sir,I want the details of fault level calculation of generator,transformer individually & for whole system. If you require any information from me.feel free for contact me sir.pl.send the answer of my question as the earliest as possible.
