write a MATLAB code to calculate and plot the motor's V curve for the given load condition.
1.) A 480-V, 60Hz, 500-hp 0.85-PF-leading eight pole delta-connected synchronous motor has a synchronous reactance of 0.6ohms and negligible armature resistance. Ignore its friction, windage, and core losses for the purposes of this problem. If the internal generated voltage, Ea, equals 480 V when the field current, If = 4A. (Assume that |Ea| is directly proportional to the field current).
a.) What is the speed of this motor?
b.) If this motor is initially supplying 500 hp at 0.85 PF lagging, what are the internal generated voltage, Ea and the armature current, Ia?
c,) How much torque is this motor producing? What is the torque angle? How near is this value to the maximum possible induced torque of the motor for this field current setting?
d.) If field current |If| is increased by 20 percent, what is the new magnitude of the armature current? What is the motor's new power factor?
