Q5) The terminal voltage (V), generated voltage (E), current (I), and synchronous reactance (jX) equation of the synchronous motor is as V = É + jÏX when the armature resistance (R) is neglected. Also, the angle between the terminal voltage (V) and the generated voltage (Ě) of a synchronous motor is called power angle (8). a) Illustrate phasor diagram of the above synchronous motor for lagging power factor and label all the vectors based on the parameters in the equation. b) Determine at what condition(s) the power angle of the above synchronous motor would be positive? c) If the above synchronous motor is operating at lagging power factor, state how to change its power factor to leading power factor.

A 3-phase, 48 kW, start-connected permanent magnet (PM) motor has a rated speed of 6600 rpm when supplied from a 110 Hz supply. The d-axis and q-axis inductances are La= 3.5mH and Lg= 4.7mH, respectively. The armature resistance and rotational losses are negligible. The motor operates without field weakening up to 6600 rpm, and a negative direct-axis current is imposed if the motor operates at speeds above 6600 rpm. The no-load terminal line-to-line voltage at 5000 rpm is 420 V (RMS). a. Determine the permanent magnet flux linkage. b. Calculate the rated phase current. c. Calculate the rated line to line voltage of the PM motor. с. d. At a speed of 7300 rpm, the PM motor operates in field weakening mode with a direct axis current of -30A and produces a torque of 30 Nm. Determine the per-phase current at this operating condition.
