Solve the following problems completely, write down the given and unknown. And draw the circuit diagram. 1 . A 440 V shunt motor has armature resistance of 0.8 ohm and field resistance of 200 ohms. Determine the back emf when giving a output 7.46 Kw at 85% efficiency. A 25 Kw, 250 V DC shunt generator has armature and field resistances of 0.6 ohm and 100 ohms respectively. Determine the total armature power developed when working... a) as a generator delivering 25Kw output and b) as a motor taking 25Kw input. A 4 poles 440 V shunt motor has a wave wound armature with 762 conductors. The full load armature current is 40 amperes and the effective armature resistance is 0.24 ohms. The flux per pole is 25 me. Allowing a brush contact drop of 2 volts. Calculate the full load speed. A dc shunt motor takes a line current of 60 A from the supply. The shunt field current is 10 percent of the line current. The armature resistance of the motor is 0.5 0. Determine the shunt field resistance if the back emf of the motor is 213 V. The field resistance of the shunt motor is 140 Q and the field current is 2 A. The motor takes a line current of 32 A from the supply. Determine the armature resistance if the back emf of a shunt motor is 260 V. The armature current of a 4 pole wave connected dc motor is 40 A. The resistance of the armature circuit is 0.23 0 and the motor is connected across the 415 V supply. The number of conductors of the armature circuit is 360 and the flux per pole is 0.05 Wb. Determine the speed of the motor. A 6 pole 230 V lap wound dc motor has an armature resistance of 0.4 Q. The armature is wound by 600 conductors and runs at a speed of 700 rpm. Determine the useful flux per pole if the armature current is 25 A. A 4 pole , 250 V dc series motor has a wave connected armature with 200 conductors. The flux per pole is 25 rnWb when motor is drawing 60 A from the supply. Armature resistance is 0.15 0 while series field winding resistance is 0.2 0. Calculate the speed under this condition. The back emf of a 230 V dc motor is 210 V. The armature of the motor draws a current of 115 A from the supply. Find the armature resistance is A 4 pole dc motor has lap connected armature winding. The flux per pole is 30 me. The number of armature conductors is 250. When connected to 230 V dc supply it draws an armature current of 40 A. Calculate the back emf and the speed with which the motor is running. Assume armature resistance is 0.6 ohm.
