A separately excited DC motor is rated at 10 kW, 300 V, 1,000 rpm, and is supplied by a three-phase controlled bridge rectifier. The power supply is sinusoidal and rated at 220 V, 60 Hz. The motor armature resistance is 0.2 ?, and the motor constant is Ka = 1.38 V-s/rad. The motor delivers rated power at ? = 0°. Calculate the speed, power factor, and efficiency for a firing angle ? = 30° if the load torque is constant. Assume that additional inductance is present to ensure continuous conduction.
Find: Speed, power factor, and efficiency for a firing angle of 30°. Assumptions: Load torque is constant, and the DC motor deliver the power P at 0° of firing angle. Additional inductance is present to ensure continuous conduction.
