Question

As in the figure, a 230 Volt-free excitation DC motor is fed to a switched mode. The time the T key is in transmission is 10 milliseconds and the time it is in the cut is 15 milliseconds. The resistance of the armature winding of the motor is 3 ohms, its speed is 1850 rev / min rpm and the field constant kg Ø = 0.04 Volt / (rev / min) rpm. Accordingly, which of the following is the armature power of the motor?

bor
U=230 V
DC
O a. 444 Watt
O b. 222 Watt
O c. 370 Watt
O d. 296 Watt
O e. 148 Watt
