when the 3 phase supply is given
to the stator of the 3 phase
induction motor the rotatory mag
feild is producd and feild is
cut by the conductor placed at
rotor and emf is induced due to
this curent is flow in cnductor
and it rotates and motor action
take place

Answer / rsr

3 phase supply fed to 3 phase stator winding produces rotating magnetic field rotating at synchronous speed. This field cuts the rotor conductors(bars) and according to faraday's law of electromagnetic induction, an emf is induced in the conductors. since the conductors are short circuited by end rings(squirrel cage), thus current stsrts flowing & it produces its own field. now, we have two fields - one produced by stator and other by rotor , the interaction of these two field led to the development of torque in the direction of rotating magnetic field as per the lenz law

Answer / deabjit dey

first current is flow,then conductor rotted atlast motor
action .

75kw drive operated motor current fluctuation from(85-130)ampere.current setting in drive is 130amp.sometimes motor trip when current limit cross 130amps.I change the drive. still current fluctuate between 80-130amps but in this time motor not trip,current setting in drive is 130amps.where is the problem?

My switchgear busbar is rated at 2000A and just imagine the actual load on busbar is 1000A. From that busbar there are 10 outgoing feeders. Now the question is will the load be 1000A on each outgoing feeder or 100A per outgoing feeder. 2nd thing how do i calculate the load on individual feeder. Thanks for your time. Please provide some clarification on this issue.
