Question
How does the current appears in rotor of squirrel cage induction motor?Question 6Select one:a.From external power supplyb.By inductionc.Through slip rings
Solution
The current appears in the rotor of a squirrel cage induction motor by induction. This is because in a squirrel cage induction motor, the rotor is short-circuited and does not have any external connection. The current is induced in the rotor due to the changing magnetic field produced by the stator. This is based on Faraday's law of electromagnetic induction which states that a change in magnetic field within a closed loop of wire induces an electromotive force (EMF) in the wire. So, the correct answer is b. By induction.
