4-3 A separately excited dc motor has the following constants: Armature resistance, R -0.5 Armature inductance negligible Torque constant, 2 N-m/A Total moment of inertia of load and armaturc, 1 = 8 kgm The load is pure inertia The motor armature is connected to a source of 110 V at i = 0 (a) Derive an expression, with numerical values, for the speed in radians per second as a function of time. Sketch the curve. (b) Calculate the steady-state speed and the time required to reach 90 percent of this value.
