18. A four-pole shunt motor haS an armature with a total of 282 conductors. If each pole face has an area of 25 8q in. and the flux density is 50,000 lines per square inch, calculate the torque in pound-feet for an armature current of 85 amp. The armature winding is wave. 14. What horsepower will be developed by the motor of Prob. 13 for a speed of 1,420 rpm? 15. A 220-volt shunt motor has au armature resistance of 0.32 ohm and a field resist- ance of 110 ohms. 1,800 rpm. Assume that the flux does not vary with load and calculate: (a) the speed of the motor when the rated line current is 62 amp (assume a 2-volt brush drop); (6) the speed regulation of the motor. At no load the armature current is 6 amp and the speed

18. A four-pole shunt motor haS an armature with a total of 282 conductors. If each pole face has an area of 25 Bq in. and the flux density is 50,000 lines per square inch, calculate the torque in pound-feet for an armature current of 85 amp. The armature winding is wave. 14. What horsepower will be developed by the motor of Prob. 13 for a speed of 1,420 rpm? 515. A 220-volt shunt motor has au armature resistance of 0.32 ohm and a field resist- ance of 110 ohms. At no load the armature current is 6 amp and the speed 1,800 rpm. Assume that the flux does not vary with load and calculate: (a) the speed of the motor when the rated line current is 62 amp (assume a 2-volt brush drop); (6) the speed regulation of the motor.
