why is it called a wound rotor? can you draw other types or explian the differences between them? eeeee 3-Phase Induction motor(wound rotor) 00000 R Staror Rotor R R

In a three-phase induction motor the maximum torque occurs at 20% slip and the equivalent resistance of the secondary is 0.04Ω per phase. Find the equivalent load resistance and the load voltage and the load current. Output power is 20 kW.

What is the difference between wound rotor induction machines and squirrel cage machines

Armature reaction in an alternator primarily affects       rotor speed     terminal voltage per phase     frequency of armature current       generated voltage per phase
