A 0,9 kW DC shunt motor is loaded by a constant torque of 12 Nm. The armature resistance of the motor is 5 Ω, and the field constant KØ = 3 Vs/rad. The motor is driven by a half wave thyristor converter. The power source is a 140 V, 50 Hz. The triggering angle of the converter is 450 and the conduction period is 1650 . Calculate the motor speed and the developed power.
