Q2. A 200V, 4-pole, wave connected shunt motor with 600 conductors in it is armature slots. The armature and shunt field resistance are 0.5Q and 2009 respectively. If the input power drawn from the mains is 8000 w and the iron and friction loss power is 960.5 w.(use flux per-pole 0.0 25Wb and brushes drop may be neglected) A- Calculate the gross torque developed by the armature, the shaft torque (useful), and the lost torque. B- Calculate the gross power developed by the armature, mechanical efficiency, electrical efficiency, and the overall efficiency. Calcultae also the maximum efficinct. Armature reaction may be neglected. (comment on your result)
