You have already answered this in a dedicated video Sir . Anyways , my comments over thick copper bars in squirrel cage rotor : SKIN EFFECT may please be reviewed & acknowledged Sir as required .

I understand your point of view. For you, this concept is easy to understand but think about those who are new to this topic. For them this may be helpful.

Changing from star to delta by triple pole double throw switch . After achieving 80% speed .

Option B is correct

In star connection line current is equal to phase current , and motor is first connnected in star hence i think option I1=I2. ( if winding of dol motor is in star) And I2=I1/√3 ( if winding of dol motor is in delta). Kindly clear me sir

In 04:59 how that vector has come to cos60 It should be cos 120 know?

If I always operate motor in star connection than what happened??

@mahender608 Жыл бұрын

Answer is "C"... √3 times decrease

Brother at the time of starting rotor is at stand still then how the induced voltage or back emf is zero during starting?

@ElectricalTalks Жыл бұрын

Its the induced emf at stator winding due to rotor mmf. Just think about the rotor current & mmf at the time of starting.
