SYNCHRONOUS MOTOR MCQ | SSC-JE | DMRC | COAL INDIA 2020 | Class 15 | हिंदी 🔴

[@vaibhavsingh6204]

I think in question 6 ans should be cos 45° because alpha is the angle by which coil is short pitched which is 30° in this case

[@montiyadav5643]

Ha

[@ElectricalEngineeringMCQs]

Indeed, Kindly consider alpha as 150degree here. Yet I will clarify this in the next session as well Vaibhav. Thank you for your kind feedback.

[@ameykhedekar6205]

Answer of 15th question should be 45°... because of salieny we get sin2d term in salient power in addition to electromagnetic Power

[@ElectricalEngineeringMCQs]

The power developed in salient pole synchronous machine P = EV/Xd * sinδ + V²/2 * (Xd-Xq)/(Xd*Xq) *sin2δ Excitation power varies as sinδ and power due to reluctance varies as sin2δ. Maximum excitation power occurs at 90° and maximum power due to reluctance occurs at 45°.

[@ameykhedekar6205]

@@ElectricalEngineeringMCQs for 90 degrees we only get maximum excitation power and reluctance power=0 (only excitation) but For 45 degree Excitation power will be 0.707 times and reluctance power will be maximum (excitation + reluctance) hencefor 45 degree we are getting maximum overall power...

[@lazyengineer4401]

Phase spread is always 60° for 3phase winding

Ans of last question .b and d

[@shubhamshende9995]

Good job sir

[@lazyengineer4401]

Phase spread= 180°/no.of phases

Thanks sir

[@pathannazir2386]

In question no 15.. we have two powers in salient pole generator ..ie excitation power and reluctance power ..but in question there is no information about which type of power..options have maximum values of both powers.how can we proceeded with knowing which power it is?

[@pathannazir2386]

Sryy with out knowing

[@ElectricalEngineeringMCQs]

I appreciate your kind observation Kindly Stay tuned I will clarify the same in next session. DO share with your friends.
