In an electric‐motor drive, similar to that shown in Fig. 2-7a, the combined inertia is J_eq = 5 × 10⁻³ kg ⋅ m². The load torque opposing rotation is mainly due to friction and can be described as T_L = 0.5 × 10⁻³ ω_L. Draw the electrical equivalent circuit and plot the electromagnetic torque required from the motor to bring the system linearly from rest to a speed of 100 rad/s in 4 s, and then to maintain that speed.
