A 600 V, dc shunt motor has armature and field resistance of 15 ohms and 600 ohms respectively. When the motor runs unloaded, the ine current is 3 A, and the speed is 1000rpm. Calculate the developed torque at a full load armature current of 50 A.
A dc series motor has a armature current of 10A at full load. The motor terminal voltage is 300V. The armature and field resistances are 2 ohm and 3 ohm respecitively. The motor speed at full load is 250 rpm. Calculate the starting torque of the m
A 1000V, 50 hp compound motor runs at a speed of 750 rpm at full load. The armature, series and shunt field resistances are 0.5 ohm, 1 ohm, and 200 ohm, respectively. The motor efficiency at this condition is 80%. Calculate the motors starting cur
An AB latch operates as follows: If A = 0 and B = 0, the latch state is Q = 0; if either A = 1 or B = 1 (but not both), the latch output does not change; and when both A = 1 and B = 1, the latch state is Q = 1.
