Consider the equations of motion of an armature controlled DC motor given by dt where vin(t) is the input voltage and Tload(t) is the input load torque. The outputs are the armature current i(t) and the motor speed w(t). The steady-state response of motors is specified by nominal voltage, stall torque, stall current, no load speed, and no load current. At steady-state operation, the motor equations satisfy bwss - K * iss = -Tfric - Tload R * iss + K * wss = vin The stall torque is the load torque required when the stead-state speed of the motor is zero. The stall current is the armature current when the motor speed is zero. The no load speed is the speed of the motor when the load torque is zero. The no load current is the current when the load torque is zero. What is the stall torque for this motor in N-m? Keep 3 significant figures, and do not include units. Use scientific notation. The constants are given below: Nominal voltage, vin(t) = 8 V Moment of inertia of the rotor, J = 0.06 kg-m² Motor viscous friction constant, b = 0.025 N-m-s Friction torque, Tfric = 0.003 N-m Armature inductance, L = 0.1 H Armature resistance, R = 0.06 Back emf constant and motor torque constant, K = 0.13 N-m/A
