2. The armature resistance of a separately excited dc motor is 0.5 0. It runs at 1,500 rpm and draws an armature current of 20 A from a 250 V dc supply. 2.1 Determine the power developed by the motor. [4] IN 2.2 Determine the torque it develops for an armature current of 10 A, stating any assumptions required. [7] 2.3 What limits the torque below the rated speed of the motor? [3]
