Calculate the efficiency of a 500V shunt motor when taking 700A from the following data taken when the motor was hot: motor stationary, voltage drop in the armature winding 15V.when the armature current was 510Afield current is 9 A at a normal voltage. Motor running at normal speed unloaded the armature current was 22.5Awhen the applied voltage was 550V; allow 2 V for brush contact drop and 1%of the rated output of 400kw for stray-load losses
