A permanent magnet DC motor is connected to a 250Volt(DC) source. Running 'light' (no mechanical load), it draws negligible current and turns at a speed of 200 Radians/second. (about 1910 RPM). The armature circuit of the machine has a resistance of one Q. Now the machine is loaded so that it is driving a load torque of 100 N-m, still connected to the 250 VDC source. How much current is it drawing? How fast is it turning?
