A 2-pole, 3 phase (PMAC) brushless-dc motor drive with a torque constant Kt and the voltage constant Ke being 0.5 in MKS units and the synchronous inductance is 15 mH.

The PMAC motor is driving a purely inertial load. A constant torque of 5 Nm is developed to bring the system from rest to a speed of 5,000 rpm in 5 s. Neglect the stator resistance and the leakage inductance. Determine and plot the voltage Va(t) and the current Ia(t) as functions of time during this 5-sec intervals.
