Question

A 220V, 1500 rpm, 10A separately excited DC motor is fed from a single-phase fully controlled rectifier with an AC source voltage of 230V. If Ra = 2Ω and the armature inductance of the drive is 50mH, calculate the no-load speeds and speeds and developed torques on the boundary between the continuous and discontinuous for (a) α = 60° (b) α = 120°.
