1. A 220-V dc series motor is running at a full-load speed of 800 rpm and draws 100 A. Calculate at what speed the motor will run when developing half the torque. The total resistance of the armature and field is 0.1 ohm. 2. A 250-V shunt motor runs at 1000 rpm at no-load and takes BA. The total armature and shunt field resistances are respectively 0.2 ohm and 250 ohms. Calculate the speed when loaded and taking 50 A.

1. A 220-V dc series motor is running at a full-load speed of 800 rpm and draws 100 A. Calculate at what speed the motor will run when developing half the torque. The total resistance of the armature and field is 0.1 ohm. 2. A 250-V shunt motor runs at 1000 rpm at no-load and takes 8A. The total armature and shunt field resistances are respectively 0.2 ohm and 250 ohms. Calculate the speed when loaded and taking 50 A.
