Exercise 2: A d.c. shunt motor, operating from a single-phase half-controlled bridge at speed of 1450 rpm, has an input voltage vs 300 sinct and a back emf of 80 V.The thyristors are fired symmetrically at a n/3 in every halfcycle, and the armature resistance is 3 02. Neglecting the armature inductance, calculate (a)The average armature current (b) The load torque. (e) The firing angle is a = n/12 calculates the speed of the motor.
