A simplex, wave-wound, 8-pole DC machine has an armature radius of \( 0.2 \mathrm{~m} \) and an effective axial length of \( 0.3 \mathrm{~m} \). The winding in the armature of the machine has 60 coils, each one with 5 turns. The average flux density at the air-gap under each pole is \( 0.6 \mathrm{~T} \). Find the following: (i) The total number of conductors in the armature winding (ii) The flux per pole generated in the machine (preferably to 5 decimals) \( \mathrm{Wb} / \mathrm{m}^{2} \) (iii) The machine constant (considering speed in \( \mathrm{rad} / \mathrm{sec} \) ) \( \mathrm{k}_{\mathrm{e}} \) or \( \mathrm{k}_{\mathrm{t}} \) (iv) The Induced armature voltage if the speed of the armature is \( 875 \mathrm{rpm} \) \( \mathrm{V} \)
