The synchronous motor of Problem 11.13 is operating under field-oriented torque control such that iD = 0. With the field current set equal to 14.5 A and with the torque reference set equal to 0.75 of the motor rated torque, the motor speed is observed to be 1475 r/min.

a. Calculate the motor output power.

b. Find the quadrature-axis current i Q and the corresponding rms magnitude of the armature current ia.

c. Calculate the stator electrical frequency

d. Find the motor line-to-line terminal voltage.
