A 4 pole DC motor has a wave connected armature with 90 slots, each slot containing 4 conductors. The flux per pole is 25 mWb and the armature has a resistance of 0.15 Ω.
When the rotor is connected to a 240 V supply and taking an armature current of 60 A, the torque developed by the armature is __________ (N-m)Enter numerical value using the virtual keypad. Round off where necessary.
