The 2-pole motor in a PMAC drive has the following parameters: R = 512, 1s = 0.1 H, and Ke=Kp = 0.5. Assume the motor is controlled such that the following space vector and phasor diagram for phase - a are accurate. With the motor in steady state, the applied Phase-A voltage is Va= 150.3139220.386[deg.). Use the equivalent circuit to answer the following questions.
