8. A separately excited motor runs at 1045rpm, with a constant field current, while taking an armature current of 50A at 120V. The armature resistance is 0.12 if the load on the motor changes such that it now takes 95A at 120V, determine the motor speed at this load. Hint: E = Καφω = KφN E101N1 Ε2 Φ2N2 :: the field current is constant and the core is assumed unsaturated = :: 01 = 02 Ε, Ν, E2 N₂
