@maajdl, thanks mate. so 4) and 5) are consequences of AR. also it seems INDUCTION MACHINE, doesn't experience this AR, as they're homopolar, thus i guess only DC and synchrounous machines experience AR. But IMs, exhibit lenz's law, that's why they get torque developed in same direction as...

@willem2, I too find it contradicting, i just neglected the question, as per me, it should be i = 2i1 = -5

isn't i = 2i1 = -5

is the rotor rotating magnetic field(R-RMF) present in squirrel cage induction motor (SCIM). Is it same as in 3 phase ROTOR winding of slip ring induction motor (SRIM), generating rotor RMF. * THE 3 phase, supply given to stator 3 phase winding of SRIM, generates (RMF), which cuts the rotor 3...

1) Is armature reaction seen in all machines ie DC, INDUCTION & SYNCHRONOUS machines ? (just answer briefly, which all machines exhibit it) 2) Is back emf in DC motor nothing but LENZ'S law, or is the generating action in DC motor called the LENZ's law, or are both same, and I'm confused ...

hello, forum members. I'm new so pardon if any error. IS the question in this pic solved correctly.
