why induction motors are of lagging type and not leading type ..

Answer / jagadeesh

because induction machines are single exited machines.
but synchronous machines are double exited, in case of
double exited machines pf can be controlled by using field
excitations(pf it may be a lagging or it may be a leading)

why induction motors are of lagging type and not leading type ..

Answer / iamdon

Induction motor is a singly excited machine.It means there
is no scope of power variation by varying the excitation.So
the nature of power factor is solely decided by the nature
of winding,which is moslty inductive.Thats why Induction
motor has always lagging power factor.

why induction motors are of lagging type and not leading type ..

Answer / ankit

this is because induction motors draw a magnetising current taht lags the supply voltage..

why induction motors are of lagging type and not leading type ..

Answer / hema chandra.m

as per electrical rools current leads the voltage in pure
capacitive loads
current and voltages are in phase in pure resistive loads
current is lagging the voltage in pure inductive loads
induction motor is pure inductive load thats why induction
motors are lagging type only not leading type.

why induction motors are of lagging type and not leading type ..

Answer / vinay kumar

induction motors draws only lagging power factor because induction takes place between stator and rotor and it draws only magnetising current

why induction motors are of lagging type and not leading type ..

Answer / pardon siabala

becouse in induction motors current lags the voltage.

Is This Answer Correct ?    1 Yes 3 No

why induction motors are of lagging type and not leading type ..

Answer / s.krishnan

induction motor just like inductive load because its have
more copper windings.so induction motor has lagging type
load not leading type load.

Is This Answer Correct ?    4 Yes 7 No

why induction motors are of lagging type and not leading type ..

Answer / k.karthik

because all motors are considered to be inductive loads.so
induction motors are lagging type and not of leading type

Is This Answer Correct ?    7 Yes 16 No
