An armature controlled DC motor has the following parameters: Tf = 0.03 Nm KT = 0.15 Nm/A Imax = 2.4 A KĘ = 0.15 Vs/rad Wmax = 5000 rpm R = 0.8 Ohms 1. Determine the following: (i) The maximum output torque. (ii) The maximum power output. (iii) The maximum armature voltage. (iv) The no load motor speed when e = Emax 2. Plot the following relationships: (i) Torque versus current (ii) Induced voltage versus speed 3. If the above motor is operated at 3000 rpm with a load torque of 0.15 N.m, determine the armature voltage
