Answer / rajesh
starting current of an induction motor z high...
bcos of the air gap present in an induction motor...
the power drawn in an induction motor is much highr than dat of an transformer due to the airgap present...

Answer / sayan
For the same rating starting current of Induction machine is
high.
| Is This Answer Correct ? | 13 Yes | 2 No |
Answer / t.sravan kumar
Due to the air gap between the stator and rotor it draws
more starting current compared to the transformer.
| Is This Answer Correct ? | 7 Yes | 0 No |
Answer / vivek singh
starting current requred to start induction motor is high
compared to transformer bcoz of the presence of air gap in
induction motor.
| Is This Answer Correct ? | 3 Yes | 0 No |
Answer / edfwe
Sayan is right.
IM is equivalent of transformer with short circuited
secondary.
| Is This Answer Correct ? | 4 Yes | 3 No |
Answer / saravana
induction machine is a rotating device, it needs high
current than transformer, at time of starting and its rotor
is closed circuit it consist of less impedance obviously it
take more current from the stator that's why it takes more
current
| Is This Answer Correct ? | 1 Yes | 0 No |
Indction motor ,as the starting current is initial
magnetising current plus the current required to overcome
the inertia of the rotor
| Is This Answer Correct ? | 1 Yes | 0 No |
Answer / ankush miglani 09718151073
AS SOME AIR GAP IS PRESENT IN INDUCTION MOTOR THE POWER
NEEDED IS HHIGH SO IT RAISES THE STARTING CURRENT IN THE
INDUCTION MOTOR

Answer / surendra pratap
Rating im is given in kw while tr. in kva for big rating of
m/c tr. have higher starting current. because at starting
inrush current is also there which is 5-10times of full
load current.
| Is This Answer Correct ? | 0 Yes | 0 No |
Answer / subbarao
induction motor takes 5 to 7 times of current at starting because its rotor short circuited and offers low impedance,obviously transformer offers high impedance compared to induction motor.
| Is This Answer Correct ? | 0 Yes | 0 No |
sir, 3phase induction motor takes different pf and different KW in three phase while running,explain reason
Motor also having losses, we call KW rating. In transformer and generator having losses but we call KVA Rating why?
