A direct current motor delivers 10 CV at full load at 1500 RP,with a power supply of 220 V and a current of 40 A. If theresistance of the inductor and that of the commutation coil add upto 0.1 ohm and the excitation coil has 0.2 ohm With a voltage dropof 1 V in each brush, Calculate the value of the fcm and theefficiency of the motor.
