engineering recuitment UPMRC JE 2024 Mock Test Electrical Machines Three Phase Induction Motor Induction Motor Field
Directions: The question consists of two statements, one labeled as ‘Statement (I)’ and the other labeled as ‘Statement (II)’. You are to examine these two statements carefully and select the answers to these items using the codes given below:
Statement (I): For producing torque in a three-phase induction machine there should be two rotating fields in the air gap and the relative speed between them should be zero.
Statement (II): There should be some relative speed between the rotating magnetic field and the rotor of the induction motor.
1
Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I).
2
Both Statement (I) and Statement (II) are individually true, but Statement (II) is not the correct explanation of Statement (I).
3
Statement (I) is true, but Statement (II) is false.
4
