(Problem 7.8 of Mohan's text). The motor in question l is to be started from rest. This motor is driving a load of inertia J = 0.04 kg·m^2, and a load torque T = 2 Nm. The motor current must not exceed 15 A. Calculate and plot both the voltage v, which must be applied to bring this motor to a steady-state speed of 300 rad/s as quickly as possible, and the speed as functions of time. Neglect the effect of La.
