How to solve a Synchronous Motor or Generator Equivalent Circuit (Electrical Power PE Exam)

Using the synchronous motor equivalent circuit, I'll teach you how to calculate the voltage drop (Ex) across the synchronous reactance (X), the stator current (I), power factor (PF), and real power (P). Practice Problem in Video: A three-phase synchronous motor is rated for 2500 HP and 1800 RPM with an operating voltage of 4,160 V three-phase AC. If the induced stator voltage (Eo) line to neutral is 2100 Volts when the DC excitation current in the rotor (Ix) is 20 Amps, find the voltage drop (Ex) in the generator due to the synchronous reactance, find the stator current I, Power Factor of the machine, and total active power consumed if the synchronous reactance (Xs) is 22 Ohms and the torque angle between Eo and E is 30 Degrees. Hint: Start by drawing out the equivalent single-phase equivalent circuit and filling in known values, then solve for the unknowns. Answers: Ex = 1,201V at 61 Degrees I = 54.60A at -29 Degrees PF = 0.97 Lagging P = 342kW Can you solve it? __________________________________ **** PE EXAM *** 🔥 SUBSCRIBE for more videos on how to pass the NCEES® Electrical Power PE Exam!    / @electricalpereview   . 🚀 Ready to PASS the NCEES® Electrical Power PE Exam?
