What will be an ideal response?
A separately excited DC motor is rated at 10 kW, 240 V, 1,000 rpm, and is supplied by a single-phase controlled bridge rectifier. The power supply is sinusoidal and rated at 240 V, 60 Hz. The motor armature resistance is 0.42 ?, and the motor constant is Ka = 2 V-s/rad. Calculate the speed, power factor, and efficiency for SCR firing angles ? of 0° and 20° if the load torque is constant. Assume that additional inductance is present to ensure continuous conduction.
