Question
SOLVE AND SHOW YOUR COMPLETE SOLUTION. ANSWERS SHOULD BE IN TWO DECIMAL PLACES. The armature of a two-pole dc machine has 30 slots, each slot has 4 conductors each. during its operation, only 75% of the conductors are directly under the pole. each pole measures 2 inches by 3 inches and produces ten million maxwells of flux. the armature core is 12 inches in length and 3.5 inches in diameter. the total resistance of the winding is 2 ohms.
e) Determine the total torque exerted by the armature core in ft - lb if the winding is simplex lap winding.
