A six pole 40 kw 400 v dc motor draws 110 a from the supply


A six pole, 40 kW, 400 V d.c. motor draws 110 A from the supply. The shunt field resistance is 200 Ohm and the armature resistance is 0.5 Ohm. The armature is wave wound with 600 conductors operates at a speed of 1200 rev/min when supplying full load.

Calculate the friction and windage (rotational) losses.
